Overload functions in C #

I read a book a few days ago and saw that in C #, I checked whether two functions in a class are heavy-duty functions. The type of Return Value of the function is not a required condition, this is not the same as C and C ++.

According to the current summary, the following conditions are met for function overloading in C:

1. The function name is the same

2. The number of function parameters is different, or the parameter type is different.

In C #, if public string show (string S) and Public void show (string s) are defined in the same class, the compiler reports an error, they are not considered as overload functions!
