The problem is that the compiler seems to dislike
"this" in the argument list as well as "goes to"
in the lambda expression.
What's up with that and how do i kill it?
What errors are you getting _exactly_. Writing "the compiler seems to dislike" doesn't explain your problem at all.
As far as the "this", I expect that either you're not using C# 3.0 or you're trying to declare the method in a non-static class. But without knowing the error, it's hard to say for sure which or whether either is correct.
I don't see anything obviously wrong with the lambda expression, but again...if you're not using C# 3.0, then it wouldn't work.
Knowing the actual error message would help a _lot_. Frankly, that's always going to be true if you are asking about help with errors that occur, either during compilation or execution.
