You could make a helper-class and call a method that opens the folderBrowserDialog and returns the selected path:

using XY;
...
private HelperClass helper = new HelperClass();

private void btn_SelectFolder_Click(object sender, EventArgs e)
{
    lbl_SelectFolderPath.Text = helper.GetFolderPath();
}

And this would be your other class:

namespace XY
{
    public class HelperClass
    {
        public string GetFolderPath()
        {
            var openFolderDialog = new OpenFolderDialog();
            if(openFolderDialog.ShowDialog() == DialogResult.OK)
            {
                return openFolderDialog.SelectedPath;
            }   
            return string.Empty;
        }
    }
}

In this case you could also make the helper-class or the method static, because you dont refer to anything to the rest of your code.
