What is the main difference between pointer and delegate with examples?
Fareed
- Nov 30th, 2006
Delegate to function--- is same as---- pointer to object.Delegates are function pointers.They are used when the function which needs to be called is not know at compile time.Pointers, on the other hand, are used to point to variables or object references in unsafe code. Thanx

Good answer! but u cant spend your time in giving all that information. Simply say Delegate is a strongly typed function pointer and pointer holds reference to a variable or pointer is a variable which holds the address of another variable.
