This may seem like a silly question but I can't remember what the difference is (if there is any) between calling a method this way: this.MethodName();

and this way MethodName();

In each case, the method is local.

As far as I know, these are equivalent.

No difference -- except that this.MethodName() must be public.  MethodName() can be private.

this.MethodName() can be used to access private methods as well...

Only difference is this.MethodName() cannot be used to access static methods.

So, basically "this" refers to the particular -instance- of the class that the method is in. (so in case of a static method there would nto be an instance hence there would be no "this" .. )

>>Only difference is this.MethodName() cannot be used to access static methods.

Or is it that "this" cannot be used WITHIN a static method?
