Learn C# programming language with this comprehensive C# tutorial series. From beginner to advanced topics, It covers everything you need to know to become proficient in C# programming.
In C#, the keywords static, const, readonly, and static readonly are frequently used, but they can be confusing. Today, we will discuss these keywords and use some examples to better understand them.
Here is the difference between Ref and Out keywords in C#:
The main difference between ref and out is that ref requires the argument to be initialized before it is passed to the called method, while out does not. ref keyword is generally used when the called method needs to both read and write the value of the argument, while out keyword is typically used when the called method only needs to write to the argument and the calling method is responsible for initializing it.
The string is an immutable type in C#, which means it can’t be changed once it’s been created. StringBuilder, on the other hand, is mutable, which means that if an operation is performed on the string object, it won’t construct a new instance in memory every time, unlike string.
In this article, we will look at the difference between a value type and a reference type in the C# programming language.
C# is a strongly-typed language, meaning every variable has a specific type that determines the values it can store and the operations it can perform. There are two main categories of Types in C#: Value and Reference type.
The diagram below illustrates the different data types in C#.
