you need to create an instance of PersonalInfo in your EmplInfoc you do that by using the new keyword. E.g.

C#

PersonalInfo personalInfo = new PersonalInfo();
personalInfo.APublicMethod();

This is very basic however, so I don't feel you will get satisfying answers here as explaining the basics takes a bit more then a few lines of explanation. I suggest you go to a bookstore and find yourself a book.

I suppose both the classes defined in the same project.
You may freely call public static members of PersonalInfo.
You may call public members of it if you have an object of type PersonalInfo (i.e. an instance of the PersonalInfo class).

The class name is PersonalInfo. It resides in a file with the name PersonalInfo.cs, at least I hope so.

As an addition to what is already said: If one of your classes is derived from the other (as person and employee suggest, but I could be totally wrong on that), you could use protected variables and methods of the parent class from within the child class.

Solution 4

You can create an instance of PersonalInfo inside EmplInfoc.

class EmplInfoC
{
   PersonalInfo o = new PersonalInfo();
}
