C# Method Overloading - c# - c# tutorial - c# net
What is member overloading in C# ?
- If we create two or more members having same name but different in number or type of parameter, it is known as member overloading. In C#, we can overload:
- methods,
- constructors, and
- indexed properties
- Because these members have parameters only.
C# Method Overloading
- Having two or more methods with same name but different in parameters, is known as method overloading in C#.
- The advantage of method overloading is that it increases the readability of the program because you don't need to use different names for same action.
- You can perform method overloading in C# by two ways:
Method Overloading
C# Method Overloading Example: By changing no. of arguments
- Let's see the simple example of method overloading where we are changing number of arguments of add() method.
using System;
public class Cal{
public static int add(int a,int b){
return a + b;
}
public static int add(int a, int b, int c)
{
return a + b + c;
}
}
public class TestMemberOverloading
{
public static void Main()
{
Console.WriteLine(Cal.add(12, 23));
Console.WriteLine(Cal.add(12, 23, 25));
}
}

C# Member Overloading Example: By changing data type of arguments
- Let's see the another example of method overloading where we are changing data type of arguments.
Method Overloading and Overriding
using System;
public class Cal{
public static int add(int a, int b){
return a + b;
}
public static float add(float a, float b)
{
return a + b;
}
}
public class TestMemberOverloading
{
public static void Main()
{
Console.WriteLine(Cal.add(12, 23));
Console.WriteLine(Cal.add(12.4f,21.3f));
}
}
