I found this great article about events, delegates and anonymous methods.
I always get lost in these matters and now-a-days you can have some really funky syntax with lambdas and everything (I mean who can honestly say that: “() => { }” is read- and understandable. Honestly).
OK – this guy (can’t find his name) has done an excellent write-up, with lots of links to other places if you want to go deep (but that’s really deep, bottomless if you want).
