c# - 如何在 openFileDialog 中保存最后一个文件夹？

Question

如何让我的应用程序存储在 openFileDialog 中打开的最后一个路径，并在新打开后恢复它？

OpenFileDialog openFileDialog1 = new OpenFileDialog();
openFileDialog1.Filter = "txt files (*.txt)|*.txt|All files (*.*)|*.*";
if (openFileDialog1.ShowDialog() == DialogResult.OK)
{
    acc_path = openFileDialog1.FileName;
    Settings.Default.acc_path = acc_path;

    foreach (string s in File.ReadAllLines(openFileDialog1.FileName))
    {
        accs.Enqueue(s);
    }
    label2.Text = accs.Count.ToString();
}
