C# How do i define methods for the same class in mutliple files?

Question

I have a class that is getting to be large. How do i define it so methods can span across different .cs files?

Answer 1

You can declare your class as partial. This allows you to split it over multiple files.

// File 1:
partial class Test {
    public void Method1() { … }
}

// File 2
partial class Test {
    public void Method2() { … }
}

Answer 2

You can use a partial class for this.

Employee_1.cs

public partial class Employee
{
    public void DoWork()
    {
    }
}

Employee_2.cs

public partial class Employee
{
    public void GoToLunch()
    {
    }
}
