What are Value types and Reference types in C#?

In C#, data types can be of two types, value types, and reference types. Value type variables contain their object (or data) directly. If we copy one value type variable to another then we are actually making a copy of the object for the second variable. Both of them will independently operate on their values, Value type data types are stored on a stack and reference data types are stored on a heap.
 
In C#, basic data types include int, char, bool, and long, which are value types. Classes and collections are reference types.
