Question

When Should i Use Method overloading in real time development,please suggest some links.

Answer 1

Overloading is used (recommended) when multiple methods have the same purpose but there is more than one way to start it.

So we rather have

int Add(int a, int b) { ...}
int Add(int a, int b, int c) { ... }

than

int Add2(int a, int b) { ...}
int Add3(int a, int b, int c) { ... }

or

int Add(int a, int b, int? c) { ...}

The last example could also be done using (C#4) optional parameters.

Another good candidate for overloading:

void ReadXml(string fileName) { ... }
void ReadXml(Stream strm) { .... }
