DOTNET 2.0

Ref & out:

Ref and Out are worked as same process in method of arguments sending reference of object .

Difference between ref and out:

Ref –it should be initialize before it use

Out – here is not need to initialize before to use it

So ref is mention input and out Is output. Using ref & out we cannot do overloading

Ex:

Void testing(ref int no)

Void testing (out int no)

---- this Is not possible .

But we can overload like this possible..

Void testing(int i);

Void testing(ref int i);
