Can you assign a function to a variable in C#? [closed]

Answer 1

You can create delegate type declaration:

delegate int del(int number);

and then assign and use it:

   del square = delegate(int x)
    {
        return x * x;
    };

    int result= square (5);

Or as said, you can use a "shortcut" to delegates (it made from delegates) and use:

Func<[inputType], [outputType]> [methodName]= [inputValue]=>[returnValue]

for example:

Func square = x=>x*x;
int result=square(5);

You also have two other shortcuts:
Func with no parameter: Func p=()=>8;
Func with two parameters: Func p=(a,b)=>a+b;
