Question

With C++, I can have one class definition in a header file, and have a multiple implementation files by including the header file.

With C#, it seems that there is no such header file, as one class should contain both definition/implementation.

I wonder if the number of lines can be very big, because one can’t separate the class into multiple files. Am I correct? I mean, in some cases, one can’t change the class design to have smaller classes. In this case, is there a way to solve this problem?

Answer 1

You can separate a class into multiple files using the partial keyword

public partial class ClassNameHere
{
}
