Various variants of C # delegates

public void Sort (comparison<t> Comparison)      
public delegate int comparison<t> (t x, t y);

This is the call to the List<maskdata>. Sort sorts the notation, where the definition of sort and the definition of the comparison delegate are as above

 
  Lstmaskdat.sort (new  comparison<             Maskdata> (delegate   (maskdata M1, maskdata m2) {  return  1  ;        })); Lstmaskdat.sort ( delegate   (Maskdata M1, Maskdata m2) { return  1  ;        }); Lstmaskdat.sort ((m1, M2)  => {         return  1  ; });

The most important thing to understand is that a delegate is a function pointer and a function should be assigned to it. This function can be a function name, or a temporary definition of an anonymous function, as above.
