You don’t specify the environment, here a code snippet for WinForms:

static class Example
{
    public static XmlTextWriter GetWriterForFolder(string fileName, Encoding encoding)
    {
        FolderBrowserDialog dlg = new FolderBrowserDialog();
        if (dlg.ShowDialog() != DialogResult.OK)
            return null;

        XmlTextWriter writer = new XmlTextWriter(Path.Combine(dlg.SelectedPath, fileName), encoding);
        writer.Formatting = Formatting.Indented;

        return writer;
    }

    public static XmlTextWriter GetWriterForFile(Encoding encoding)
    {
        SaveFileDialog dlg = new SaveFileDialog();
        dlg.Filter = "XML Files (*.xml)|*.xml";

        if (dlg.ShowDialog() != DialogResult.OK)
            return null;

        XmlTextWriter writer = new XmlTextWriter(dlg.FileName, encoding);
        writer.Formatting = Formatting.Indented;

        return writer;
    }
}

The GetWriterForFolder function lets the user to select a folder where file will be saved, you have to provide a file name as parameter. Like this:

string fileName = "EFIX.036003.CMF.FIX." + sDate + ".CMF003.xml";
XmlTextWriter writer = Example.GetWriterForFolder(fileName, Encoding.UTF8);

The GetWriterForFile function let the user select a folder and the file name to use. Like this:

XmlTextWriter writer = Example.GetGetWriterForFile(Encoding.UTF8);
