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 −
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
