public void Speak()

{

MessageBox.Show("Hello...");

}

}

Now, update your initial TestApp class to make use of this new class type, and comment out the

previous Windows Forms logic:

using System;

// Don't need this anymore.

// using System.Windows.Forms;

class TestApp

{

static void Main()

{

Console.WriteLine("Testing! 1, 2, 3");

// Don't need this anymore either.

// MessageBox.Show("Hello...");

// Use the HelloMessage class!

HelloMessage h = new HelloMessage();

h.Speak();

}

}

You can compile your C# files by listing each input file explicitly:

csc /r:System.Windows.Forms.dll TestApp.cs HelloMsg.cs

As an alternative, the C# compiler allows you to make use of the wildcard character (*) to

inform csc.exe to include all *.cs files contained in the project directory as part of the current

build:

csc /r:System.Windows.Forms.dll *.cs

When you run the program again, the output is identical. The only difference between the two

applications is the fact that the current logic has been split among multiple files.
