How to create a Textbox to save a path

I've seen a lot of times, programas that have something like textbox that is used to get/save the path of something... There's a button on it and when you click on it opens a prompt for you to select the directory, you know ? How Could I do that? I have to read a file.txt, and I need my application to open this file.txt, how I open this "prompt" ? Then I need to save a destination path the same way... Is it actually a textboxor something else?

Thanks

You can use the OpenFileDialog

string path;
OpenFileDialog file = new OpenFileDialog();
if (file.ShowDialog() == DialogResult.OK)
{
    path = file.FileName;
}

Now the file path is saved to the string, and you can then manipulate the file.

You need to add an OpenFileDialog to your form (MSDN has more info)

This sample should explain it better than I could!

private void button1_Click(object sender, System.EventArgs e)
{
Stream myStream = null;
OpenFileDialog openFileDialog1 = new OpenFileDialog();

openFileDialog1.InitialDirectory = "c:\\" ;
openFileDialog1.Filter = "txt files (*.txt)|*.txt|All files (*.*)|*.*" ;
openFileDialog1.FilterIndex = 2 ;
openFileDialog1.RestoreDirectory = true ;

if(openFileDialog1.ShowDialog() == DialogResult.OK)
{
    try
    {
        if ((myStream = openFileDialog1.OpenFile()) != null)
        {
            using (myStream)
            {
                // Insert code to read the stream here.
            }
        }
    }
    catch (Exception ex)
    {
        MessageBox.Show("Error: Could not read file from disk. Original error: " + ex.Message);
    }
}
}

You need to create a button next to the textbox.

In the button's Click event handler, create and show a SaveFileDialog, then assign its result to the textbox's text.
