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
