I am having trouble sending a `List<>` to a textbox and i am not sure what the trouble is. I have checked so the List actually has values in it and that it gets properly transfered from the class into this block. 

The code:

```
  public void Listtest(List<string> m_customers)
    {
        lstRegistry.Items.Clear();

        for (int index = 0; index == m_customers.Count; index++)
        {
            lstRegistry.Items.Add(m_customers[index]);
        }
    }

```

The other class that is sending the `List<>`

```
     class CustomManager
{
    //private List<Customer> m_customers;
    List<string> m_customers = new List<string>();        

    public void CreateNewString(string adresslist, string emaillist, string phonelist, string namelist)
    {
        MainForm strIn = new MainForm();
        string newlist = string.Format("{0,-3} {1, -10} {2, -20} {3, -30}", namelist, phonelist, emaillist, adresslist);           
        m_customers.Add(newlist);  //líst is created.
        strIn.Listtest(m_customers);           
    }
}  

```

I just cant get it to work and I am really stuck. :/ 

Thanks for any and all help and ideas!!!
