C# Programming Insights

C# has a fast and easy-to-implement object serialization into JSON with the help of JsonSerializer.

In C#, IEnumerable was not designed to be modified so it is best to use List when trying to modify a collection

This is a step-by-step guild to install Visual Studio. It is a great IDE to work with and has rich features and debugging tools.

In C#, JsonSerializer Deserialize is the best JSON Deserializer method as it is the fastest based on my testing. It has native C# support.

In C#, Array Copy is best to use when copying part of an array to another array. It fits on one line and it is fast. Also, it has no limitation on types.

The best method for combining two arrays into one in C# is Enumerable Concat. It is fast, easy to read, and fits on one line.

In C#, the static array empty method is the best initializer for an empty array. It does what it says and quick to use by using one step.

There are 4 main ways to initialize a C# array. One initializes to null or default, array initializers, shorthand and new operator.

A C# string can be converted to a byte array and visa versa. C# provides encoders classes that can do this operation by GetString and GetBytes.

The Array Indexer is the best way in C# to assign values for the entire array. It's fast, less code and no need to convert between types.

Arrays are a fundamental data structure in programming. C# provides a fast, simple and generic array implementation

There are a couple of ways to have a one-to-many collection type. You can use a dictionary in C# with a List or List of KeyValuePairs. Each with pros and cons.

TryGetValue is the best .NET method for getting values from a dictionary. It performs better and takes up less code than using ContainsKey with Indexer.

A Fix For Collection Was Modified And Enumeration Not Executed comes by copying parts or the whole dictionary in the reader thread.

To get a list from the dictionary's keys, C# has LINQ's ToList is concise and easy to read, and just as fast as the list constructor.

There are small differences in creating a C# dictionary in a function, but the Index Initializer has the best performance and easiest-to-read syntax.

In .NET, to make a dictionary case insensitive it must be done in the declaration. There are three options and OrdinalIgnoreCase is the fastest.

Changing the C# dictionary key is only possible by removing the existing key and adding the new key and existing value. This has the best performance.

Mapping two lists into a dictionary is best done manually. It has the best performance and also can handle duplicate keys without throwing exceptions.

The best way in C# to convert a list to a dictionary is to use the dictionary indexer. It is fast enough, has simple syntax, and works with duplicates.

The best dictionary merge method is the merge loop method. You can write yourself and it is faster than the C# LINQ methods.

ElemenatAt lets a dictionary be accessed by numeric values, but this is far not the best way in C#

C# provides Collection Initializers syntax to initialize dictionaries to simple, quick, and readable code.

In .NET, Dictionary performs much better than Hashtable. It is a clear example why it is better to use a generic collection type.

In C#, TryGetValue is best suited for the check if the key exists in the dictionary because it checks then returns the value too.

Using a LINQ Extension method is the best way to sort a dictionary by value. It is quick and easy to implement.

TryGetValue is the best method in C# for updating a value because it checks if the key exists and retrieves and returns the value to use right away.

The best way in .NET to get keys by their value from a dictionary is to use the dictionary and list combo. This gives speed and flexibility.

Dictionary fastest C# methods are iterating over just the Keys and Values but looping through both Key and Value a list with a class container performs better

In C#, When comparing List to IEnumerable, List has more functionality but using LINQ with IEnumerable it has better performance than List.

The fastest C# method for converting a system array to a list is to use an array cast and then use ToList. It is short and compact and easy to read.

The best methods for intersect, union, and except are with the HashSet collection type. The HashSet functions are faster than LINQs.

The best C# method for getting unique items from a list is to use a combination of HashSet and List. It has good performance and the order of the items is preserved.

Cloning a C# list is a matter of understanding the differences in shallow, and deep copies and the difference between value and reference types.

C# list are the backbone of collections and often the most used. They are versatile and flexible, they increase and decrease the underline array automatically.

Strings are some of the first data types to learn in the csharp so it becomes important to manipulate strings, and to parsing strings

Code snippet is is sections of brief code and explanation that could be useful to you for simple yet fundamental issues that could arise.

The best C# method for finding an item in a list is the List Find method, however, the best collection type for finding an item in the dictionary.

The best .NET method to convert a list to a string with a delimiter is the string join method. It is by far the fastest, it is compact, and also easy to set up.

Initializing the C# list using the in-line method is best used when there are only a few items and also where the list won't change much very often.

The best sorting method in C# is LINQ's order by function. It is the fastest method and it is compact.

The best way in C# to access an item on a list is to use the Indexer property. It is extremely fast and once used to the syntax, it becomes a go-to property.

The most effective function for getting a substring between two C# strings is the span slice. Speed is an important factor because that has an impact on the end user.

The best .NET method for getting the first n characters is span slice. Performance is the best metric to determine which is best because it affects the end users.

The best way in C# to get the last n characters is to use a string substring. It has one of the fastest methods and is readable so you don't have to guess what it does.

The overall best way in C# to solve getting a substring after finding a keyword is with Span Slice because of the huge performance gain.

In C#, Span Slice came at the fastest first character removal method at about half a second while substring, range operator, remove, and trim start were pretty fast.

Data can have duplicated and errors can be in the inputs and fields it is important to efficiently remove the first keyword occurrence from a C# string.

Getting a substring before or after a certain character is common in parsing C# strings, user data, database data, and automatic data generated by scripts.

In C#, String Equals comparing two strings to find out if they are exactly the same. The comparison is case-sensitive and usually used in conditional statements.

In C#, the method string replace is a string and character substitute with another string. It finds the characters and then replaces them it a new set of characters.

In C#, string trim removes space, tabs, and various lengths of whitespace at the beginning or end of a string. This is good for user inputs.

String insert puts a single string between a section of the string. The first parameter is an index of insert and the second parameter is the string to insert.

In C#, String remove takes an existing string and based on the start index and length for removal then will return a string with that section removed.

The substring method in C# copies a chunks of an existing string. It returns a sub-section of the original string and depends on the selected index range.

In .NET, Array vs Lists vs Linked Lists is a common collection type, each has pros and cons so it is important to understand these as we make our collection choices.

In C#, the exception CS1736:Default parameter value must be a compile-time constant comes when assigning an optional parameter value is not a constant or default value.

C# Dictionary using best practices with the right key scales well over large datasets. There are several pitfalls that should be avoided.

One way to copy files to the output folder is to edit the .csproj file and add a command to copy files from a certain directory into the output folder.

In .NET, list and dictionary are useful collection types. They are accessible and convenient to use. There are advantages over an array or hash tables.

Want to find out if a DLL or assembly is targeting 32bit or 64bit then Visual Studio comes with a handy tool called Corflags accessed by the command prompt.

Hex is a base 16 number system and C# has a built-in function that can convert a string hex value into an int value.

String vs StringBuilder are similar and in most cases in .NET, we will use string but we need a more efficient option in StringBuilder.

When testing or writing programs that generate files you may want automate opening the file in code than manually opening those files.

The new line in .NET is a special sequence that can be inserted into a string. Represented as a backslash n this works as if you pressed return on the keyboard.

Getting a substring before or after a certain character is common in parsing C# strings, user data, database data, and automatic data generated by scripts.
