Setting the initial directory of an SaveFileDialog?

Question

I\'d like a SaveFileDialog with the following behavior:

• The first time you open it, it goes to \"My Documents\".

• Afterwards, it goes to the

This is what I ended up with, that goes along with where the OP wanted to point their dialog:

Microsoft.Win32.SaveFileDialog dlg = new Microsoft.Win32.SaveFileDialog();
dlg.InitialDirectory = null;

// May or may not want "saves", but this shows how to append subdirectories
string path = (Path.Combine(Environment.ExpandEnvironmentVariables("%USERPROFILE%"), "My Documents") + "\\saves\\");  

if (!Directory.Exists(path))
    Directory.CreateDirectory(path);

dlg.InitialDirectory = path;
dlg.RestoreDirectory = true;

if (dlg.ShowDialog().Value == true)
{
    // This is so you can have JUST the directory they selected
    path = dlg.FileName.Remove(dlg.FileName.LastIndexOf('\\'), dlg.FileName.Length - dlg.FileName.LastIndexOf('\\'));

    string filePath = Path.Combine(path, fileName);

    // This is "just-in-case" - say they created a new directory in the dialog,
    // but the dialog doesn't seem to think it exists because it didn't see it on-launch?
    if (!Directory.Exists(path))
        Directory.CreateDirectory(path);

    // Remove a file if it has the same name
    if (File.Exist(filePath))
        File.Delete(filePath);

    // Write the file, assuming you have and pass in the bytes
    using (FileStream fs = new FileStream(filePath, FileMode.CreateNew, FileAccess.Write)
    {
        fs.Write(bytes, 0, (int)bytes.Length);
        fs.Close();
    }
}
