Difference between value types and reference types.

Following are the differences between value types and reference types in C#:

• Value types are stored on the stack where as reference types are stored on the managed heap
• Value type variables directly contain their values where as reference variables holds only a reference to the location of the object that is created on the managed heap
• There is no heap allocation or garbage collection overhead for value-type variables. As reference types are stored on the managed heap, they have the over head of object allocation and garbage collection
• Value types cannot inherit from another class or struct. Value types can only inherit from interfaces. Reference types can inherit from another class or interface
