Question

I have this code:

public partial class Form1 : Form
{
    public Form1() { InitializeComponent(); }

    private void button1_Click(object sender, EventArgs e)
    {
        FolderSelect("Please select:");
    }

    public static string FolderSelect(string txtPrompt)
    {
        // Now, we want to use the path information to population
        // our folder selection initial location
        string initialCheckoutPathDir = ("C:\\"); 
        System.IO.DirectoryInfo info =
            new System.IO.DirectoryInfo(initialCheckoutPathDir);

        FolderBrowserDialog FolderSelect = new FolderBrowserDialog();
        FolderSelect.SelectedPath = info.FullName;
        FolderSelect.Description = txtPrompt;
        FolderSelect.ShowNewFolderButton = true;

        if (FolderSelect.ShowDialog() == DialogResult.OK)
        {
            string retPath = FolderSelect.SelectedPath;

            if (retPath == null)
                retPath = "";

            DriveRecursion(retPath);
        }
        else
            return "";
    }
}

So i have a WindowsForm with a button. The user presses the button, and the FolderBrowserDialog appears. Once the user selects a drive, i want the form (with the button) to close as well.

I haven’t been having any luck. Any ideas? Syntax would greatly be appreciated.

After the FolderSelect returns DialogResult.OK, you need to call this.close. So like this:

 public string FolderSelect(string txtPrompt)
    {
        //Value to be returned
        string result = string.empty;

        //Now, we want to use the path information to population our folder selection initial location
        string initialCheckoutPathDir = (@"C:\"); 
        System.IO.DirectoryInfo info = new System.IO.DirectoryInfo(initialCheckoutPathDir);
        FolderBrowserDialog FolderSelect = new FolderBrowserDialog();
        FolderSelect.SelectedPath = info.FullName;
        FolderSelect.Description = txtPrompt;
        FolderSelect.ShowNewFolderButton = true;
        if (FolderSelect.ShowDialog() == DialogResult.OK)
        {
            string retPath = FolderSelect.SelectedPath;
            if (retPath == null)
            {
                retPath = "";
            }
            DriveRecursion(retPath);

            result = retPath;
            //Close this form.
            this.Close();
        }
        return result;
    }

Edit:
For some reason your FolderSelect method is static. You should remove the static so it has a reference to the form.
