How to pass parameters to a method in C#?
To pass parameters to a method in C#, let us see how to pass parameters by value. In this mechanism, when a method is called, a new storage location is created for each value parameter.
The values of the actual parameters are copied into them. Hence, the changes made to the parameter inside the method have no effect on the argument.
Here is the example showing how to pass parameters to a method −
Example
using System;
namespace Demo {
class NumberManipulator {
public void swap(int x, int y) {
int temp;
temp = x;
x = y;
y = temp;
}
static void Main(string[] args) {
NumberManipulator n = new NumberManipulator();
int a = 50;
int b = 150;
Console.WriteLine("Before swap, value of a : {0}", a);
Console.WriteLine("Before swap, value of b : {0}", b);
/* calling a function to swap the values */
n.swap(a, b);
Console.WriteLine("After swap, value of a : {0}", a);
Console.WriteLine("After swap, value of b : {0}", b);
Console.ReadLine();
}
}
}Output
Before swap, value of a : 50 Before swap, value of b : 150 After swap, value of a : 50 After swap, value of b : 150
