[c#] Static extension methods

Is there any way I can add a static extension method to a class.

specifically I want to overload Boolean.Parse to allow an int argument.

Would an extension for int work?

public static bool ToBoolean(this int source){
    // do it
    // return it
}

Then you can call it like this:

int x = 1;

bool y = x.ToBoolean();

No, but you could have something like:

bool b;
b = b.YourExtensionMethod();
