When a variable needs to be passed into a subroutine, this is done through the use of parameters. The subroutine can then use these parameters to execute its code. Parameters should be written inside the subroutine brackets, along with their variable type. In addition, multiple parameters should be separated by commas (",").
Example
1 namespace Project
2 {
3 class Program
4 {
5 static void Main(string[] args)
6 {
7 greeting("Geoff");
8 greeting("Bob");
9 }
10
11 static void greeting(string name)
12 {
13 Console.WriteLine("Hello, " + name);
14 }
15 }
16 }
17 //Output:
18 //Hello, Geoff
19 //Hello, Bob
