Function

1, Concept: is a code block with input parameters, output parameters, return values.

2, the wording:

Modifier return value type function name (input parameter, input parameter)

{

Method segment

return value;

}

3. Comments:

(1) input parameter format: parameter type + variable name. Can not write

(2) return value type---Void is no return value, function body cannot write return

(3) "///" can bring up the comment of the function, which is convenient to view when referencing

(4) need to be under the same namespace as the main function

4. Example:

 Public int Jiafa (int A,int  b) {    return a +b;}

5. Call Method:

Enter a parameter call in the main function

Static void Main (string[] args) {    int a ,    b; 3 ;     5 ;     New Class (); // Initialize the class where the function resides first    C.jiafa (A, b); // call a function, or you can output }
