anonymous delegates

[bri189a]

Okay, I've read several articles about this. I don't see what the big deal is. Maybe it's the examples - don't seem to be accomplishing anything magic that you couldn't do with delegates as they are in 1.1 - can anyone expand on what's the big deal is in a real world example?

It's all about ease of use. If your delegate is only one or two statements then it's the way to go. Plus the ability to incorporate local variables makes it handy. One instance where I've used them is in a tranformation matrix control. You can translate, scale, and rotate the matrix in any order, so I just create an anonymous delegate for each step.

They can also make unit tests involving callbacks / events far cleaner to write as well.

Basically there's no "magic", just a convenience. Before someone had a one line if, all if's looked like:

if (expression == true)
{
   return true;
}

 

Someone said "hey, let's make it more convenient in certain circumstances":

if (expression == true) return true;
