Answer:
Reference
Explanation:
The Reference type variable is such type of variable in C# that holds the reference of memory address instead of value. Examples for reference type are classes, interfaces, delegates and arrays.
We can pass parameters to the method by reference using <em>ref </em>keyword
It’s mandatory to initialize the variable value before we pass it as an argument to the method in c#
For example,
int x = 10; // Variable need to be initialized
Add(ref x); // method call
If you pass parameters by reference in method definition, any changes made to it affect the other variable in method call.
Here's a sample program:
using System;
namespace ConsoleApplication
{
public class Test
{
public static void Main()
{
int i = 10;
Console.WriteLine("i=" + i);
Add(ref i);
Console.WriteLine("i=" + i);
Console.ReadLine();
}
public static void Add( ref int j)
{
j = j + 10;
Console.WriteLine("j="+j);
}
}
}
Output:
i=10
j=20
i=20
