These parts are coming from the Language Specification document:
x => x + 1 // Implicitly typed, expression body
x => { return x + 1; } // Implicitly typed, statement body
(int x) => x + 1 // Explicitly typed, expression body
(int x) => { return x + 1; } // Explicitly typed, statement body
(x, y) => x * y // Multiple parameters
() => Console.WriteLine() // No parameters
delegate (int x) { return x + 1; } // Anonymous method expression
delegate { return 1 + 1; } // Parameter list omitted
// Example:
delegate bool Filter(int i);
void F() {
Filter f = (int n) => n < 0;
list.FindAll(f);
}
delegate void D();
void F() {
int n;
D d = () => { n = 1; };
d();
// Error, n is not definitely assigned
Console.WriteLine(n);
}
