C#_ Basic _ Methods and method overloads (10)

Method: A mechanism that puts a piece of code together and makes repeated calls.

Grammar:

* [Private] static return value type function name (parameter list)
* {
* Function code;
*
* return value;
* }
*
* Public: Is the access modifier, which can be accessed publicly
* Static: Static
* Return value type: Void if no return value
* Method Name: First letter uppercase, remaining lowercase
* parameter list: The condition that this method must be provided to complete this method
* Return Effect: 1. End method; 2. Returns the value to return in the method

1 Exercise 1: Calculate the maximum value between two integers2         /// <summary>3         ///compares the size of two integers and returns a maximum value4         /// </summary>5         /// <param name= "NUM1" >integer</param>6         /// <param name= "num2" >integer</param>7         /// <returns></returns>8          Public Static intGetmax (intNUM1,intnum2)9         {Ten             returnNum1 > num2?num1:num2; One         } A  - Exercise 2: Read the input integer, if the user entered a number is returned, otherwise prompt the user to re-enter -          Public Static voidGetInt () the         { -              while(true) -             { -                strings =console.readline (); +                 Try -                 { +                     intnum =Convert.ToInt32 (s); A Console.WriteLine (num); at                      Break; -                 } -                 Catch  -                 { -Console.WriteLine ("input error, re-enter"); -                     in                 } -             } to Exercise 3: Judging whether it is a leap year +      Public Static BOOLIsrun (intYear ) -         { the             BOOLB = (Year/ -==0) || (Year/4==0&& Year% -==0); *             returnb; $}

Method overloads:

Concept: Method name is the same, parameter list is different (parameter type, number of parameters)

1         ///compare two-digit maximum values2          Public Static intGetmax (intNUM1,intnum2)3         {4             returnNum1 > num2?num1:num2;5         }6         //three number of maximum values7          Public intGetmax (intNUM1,intNUM2,intnum3)8         {9             inttemp = NUM1 > num2?num1:num2;Ten             returnTemp > num3?temp:num3; One}
