# What is function signature in oops.

Hi...\
I would like to know that what is [function](https://www.mindstick.com/articles/13001/multi-statement-table-valued-user-defined-function-in-sql-server) [signature](https://www.mindstick.com/interview/516/explain-about-xml-signature) in [oops](https://www.mindstick.com/articles/1558/introduction-to-oops-object-oriented-programming-system) and how to [implement it in c#](https://www.mindstick.com/forum/159868/what-is-dependency-injection-and-how-can-i-implement-it-in-c-sharp).

Function signature basically contains types of parameters, number of parameters and sequence of parameters.

Return type is not part of function signature.

We use concept of function signature when we use method overloading.
