Overloading in C#

Anil Kumar Murmu

Hi All,

I have gone through several interviews last month, and one of the question on which i need clarification is overloading.

Can anyone please let me know, while we move ahead with the concept of Method Overloading is it mandatory to look after the return type of methods.

Say i have 2 methods in a class:

public int Addtion(int a, int b)

{

return a+b;

}

public void Addition(int a, int b)

{

}

Are these two methods will be considered as overloading as well?

i appreciate any inputs.

Thank You

Hi,..

the example u gave is not correct for overloading.
Overloading always work on no. of parameters as well as types of parameters like
This is example of overloading
public int Sum(int a, int b)
{
return a + b;
}
public int Sum(int a, int b,int c)
{
return a + b;
}

And this is not , which give u error

public int Sum(int a, int b)
{
return a + b;
}
public string Sum(int a, int b)
{
return "Hi";
}

Hence on the basis of return type one cant have a overloading..
Hope now the concept is clear :)

Cheers!!!!!!!!!

Your method is not considered as "overloaded". You will get the error. Methods cannot be overloaded based on their return type. A more clear discussion is available here:

Thank you for the quick response, what would be taken into consideration if we have following code: will be a concept of method overloading? public int Addition(int a, int b) { return a + b; } public void Addition(string a, string b) { Console.WriteLine("Sum is :: {0}",a+b); }
