Method Parameters in C#

The parameters are used to pass and receive data from a method. Let us first see the syntax −

• Access Specifier − This determines the visibility of a variable or a method from another class.
• Return type − A method may return a value. The return type is the data type of the value the method returns. If the method is not returning any values, then the return type is void.
• Method name − Method name is a unique identifier and it is case sensitive. It cannot be same as any other identifier declared in the class.
• Parameter list − Enclosed between parentheses, the parameters are used to pass and receive data from a method. The parameter list refers to the type, order, and number of the parameters of a method. Parameters are optional; that is, a method may contain no parameters.
• Method body − This contains the set of instructions needed to complete the required activity.

Example

Let us see an example −

 Live Demo

using System; public class NumberManipulator {    public int FindMax(int num1, int num2) {       int result;       if (num1 > num2)          result = num1;       else          result = num2;          return result;    }    public static void Main(string[] args) {       int a = 500;       int b = 750;       int ret;       NumberManipulator n = new NumberManipulator();       ret = n.FindMax(a, b);       Console.WriteLine("Max value = "+ret );    } }

Output

This will produce the following output −

Max value = 750
