difference bwn stack and heap?????

The Types in .NET Framework are either treated by Value Type or by Reference Type. A Value Type holds the data within its own memory allocation and a Reference Type contains a pointer to another memory location that holds the real data. .....more about.....http://net-informations.com/faq/general/valuetype-referencetype.htm

Just one point on Abhay's post.

Value types are not always stored on the stack.

For example, if they are:

1. Static or instance fields of reference types; or

2. Static fields of value types,

then they are stored on the heap.

 

The stack is a data structure in memory used for storing items in a last-in, first-out manner (LIFO). The stack contains both local variables and the call stack. In C#, value types are stored on the stack.

The heap or managed heap is a data structure in memory where all objects—reference types—are stored. When an object is instantiated, the object is stored on the heap as a block of data containing its data members. Then, the memory address of the block is stored in a reference variable. Future references to the object are through the reference variable.
