Form Class, Keep getting a "System.StackOverflowException" on a simple code test

Question

I have been trying to implement and adapt my coding style moving form more of a procedural programming style but have been running into problems, when trying to run another class working with the systems registry. Furthermore the code works fine in the main class. P.S I come form a scripting background.

Code Error: An unhandled exception of type 'System.StackOverflowException' occurred in System.Windows.Forms.dll

I have cut down the code from the main application to make it easier to find the problem.

Main Form Class:

public partial class Form1test : Form
{
    // An unhandled exception of type 'System.StackOverflowException' 
    // occurred in System.Windows.Forms.dll
    public Form1test() 
    {
        TestClass lsr = new TestClass();
        lsr.chkRegAct();
        InitializeComponent();
    }  
}

TestClass:

class TestClass : Form1test
{
   //rest of code
}

Answer 1

TestClass is derived from Form1Test.

You create a new TestClass which results to calling the constructor of base class (Form1Test) which generates a new TestClass which results to calling the constructor of base class (Form1Test) which generates a new TestClass which results to calling the constructor of base class (Form1Test) which generates a new TestClass which results to calling the constructor of base class (Form1Test) which generates a new TestClass which results to calling the constructor of base class (Form1Test) which generates a new TestClass which results to calling the constructor of base class (Form1Test) which generates a new TestClass which results to calling the constructor of base class (Form1Test) which generates a new TestClass which results to calling the constructor of base class (Form1Test) which generates a new TestClass which results to calling the constructor of base class (Form1Test) which generates a new TestClass which results to calling the constructor of base class (Form1Test) which generates .....

StackOverflowException due to lot of function calls caused by infinite recursion.
