Find method with specific argument using regular expression in VS2012

Question

I want to find an (overloaded) method X where the argument in position Y has the value Z.

Example:

AddMailToQueue("a", "b", "c", 2);
AddMailToQueue("a", "b", "c", 2, "d");

X: AddMailToQueue
Y: 4
Z: 2

The method name X may or may not be prefixed (eg this.AddMailToQueue).

I came up with the following: .*AddMailToQueue\(.+2.*\); but this regex does not take into account the position of the argument and will also return matches where Z = 20, 21, etc.

My reasoning is that the comma separating the arguments can probably be used to pinpoint argument Y.

Probably you want a .NET solution, but here is a regex that works in Java, then maybe you can convert it.

AddMailToQueue\s*\(([^,]+,){3}\s*2\s*[,)]

Things get easier if you start counting your parameters from zero. You would put the parameter's index Y where you see 3 and the paramater's value Z where you see 2.

See it working

It works perfectly, no changes required! Also, removing the initial .* (just before the method name) made the search much faster!
