Use the editor.

editor..?? i m in VS2012

Yes, and how do you edit the code in VS2012?

do you need to? you can overload the function so both versions are valid.

I need to.

Then, yes - use the editor. In your case use VS2012.

Personally, I would visit each usage and change it to ensure that I didn't do anything to change effected code.

PS: Ctrl+H to bring up the replace menu. You can choose to replace all in Selection, Block, Project or Solution from there

If you don't have R# then delete/comment out the original overload, compile, fix all errors, done.

You can't really do that - because nobody knows what value or variable should be added in!
If the existing code is

C#

myClass.add(index, count);

Should it become:

C#

myClass.add(index, count, numberOfBananas);

Or

C#

myClass.add(index, count, 0);

It all depends on the context of why your code is calling the method.
But...the easiest way may be to change the definition of your "new" method:

C#

public int add(int a, int b, int c = 0)
   {
   return a + b + c;
   }

In which case your external code will need no changes at all as the final value will be defaulted to zero unless it is specified.
