What does the syntax in C mean

Question

I only recently discovered this syntax in some of the discussions on this site, but Google and other search engines tend to ignore anything other than letters and numbers in searches, making it impossible to find "=>."

So, could someone please explain what it is and how it is used?

Answer 1

Here's a simple MSDN example.

delegate int del(int i);
del myDelegate = x => x * x;
int j = myDelegate(5); //j = 25

The input parameters are anything before the =>, and the expression is everything after the =>. Multiple input parameters are possible. Linq makes extensive use of lambdas.
