C class without main method

Question

I'm learning C# and am somewhat new to it, so please excuse my seemingly inane inquiry. I've worked with Java before, and I've noticed that C# projects likewise require a main() method in the main class.

What if I want to make a class that isn't a main class, but that I can import into one?

When I compile (through cmd using csc File.cs), the compiler complains that the.exe it would generate lacks a main() method. Is this to say that I was mistaken and that every class need a main() method, or that I'm compiling it incorrectly?

Perhaps the issue is in the code (as I'm relying on my Java syntactic expertise), which looks like this:

public class Class
{
    int stuff;
    public Class(int stuff)
    {
        this.stuff = stuff;
        stuff();
    }
    public void method()
    {
        stuff();
    }
}

Not every single class need the main method. This is also confirmed in the MSDN documentation. Read this: https://docs.microsoft.com/en-us/previous-versions/visualstudio/visual-studio-2010/acy3edy3(v=vs.100)?redirectedfrom=MSDN

The Main method, which serves as the application's entry point, can be kept in just one class and these are the ways you can make that happen: static void Main(string[] args) or static void Main() or static int Main(string[] args) or static int Main()
