What is the difference between a value type and a reference type?

Main difference between value type and reference type is value type copy a data while reference types share a single copy of their data. Value Type immutable its mean when we create a instance with a value type its create a unique copy of data and it can’t change but reference type is mutable its value can be change ..

What are reference types and value types in C#?

Value types and reference types are the two main categories of C# types. A variable of a value type contains an instance of the type. This differs from a variable of a reference type, which contains a reference to an instance of the type.

The process of Converting a Value Type (char, int etc.) to a Reference Type(object) is called Boxing. Boxing is implicit conversion process in which object type (super type) is used. The Value type is always stored in Stack. The Referenced Type is stored in Heap.

Is String a value type or a reference type?

reference type
String is a reference type, but it is immutable. It means once we assigned a value, it cannot be changed. If we change a string value, then the compiler creates a new string object in the memory and point a variable to the new memory location.
