OpenFileDialog的初始目录

Question

文件对话框必须打开关闭之前使用的最后一个目录位置,但我不知道如何执行此操作.我的同事只给我看了一个单词的例子,当你单击"文件"它显示最后使用的文件时,他告诉我使用寄存器或INI文件,这是我以前从未使用过的.

这是我正在使用的代码:

string f_sOudeLocatie = @"D:\path\is\classified";

private void btBrowse_Click(object sender, EventArgs e)
{
    OpenFileDialog fdlg = new OpenFileDialog();
    fdlg.Title = "Zoek de CSV file";
    fdlg.InitialDirectory = f_sOudeLocatie;
    fdlg.Filter = "All files (*.*)|*.*|All files (*.*)|*.*";
    fdlg.FilterIndex = 1;
    fdlg.RestoreDirectory = true;
    if (fdlg.ShowDialog() == DialogResult.OK)
    {
        tbGekozenBestand.Text = fdlg.FileName;
        tbVeranderNaamIn.Text = Path.GetDirectoryName(fdlg.FileName);
        f_sOudeLocatie = Path.GetDirectoryName(fdlg.FileName);
        f_sSourceFileName = fdlg.FileName;
        f_sDestFileName = Path.GetFileName(Path.GetDirectoryName(fdlg.FileName)) + ".csv";
        btOpslaan.Enabled = true;
        tbVeranderNaamIn.ReadOnly = false;
    }
}

如果你OpenFileDialog在按钮点击事件之外创建它,它应该记住你去过的最后一个文件夹

string f_sOudeLocatie = @"D:\path\is\classified";
OpenFileDialog fdlg = new OpenFileDialog();

public Form1()
{
    InitializeComponent();
    fdlg.Title = "Zoek de CSV file";
    fdlg.InitialDirectory = f_sOudeLocatie;
    fdlg.Filter = "All files (*.*)|*.*|All files (*.*)|*.*";
    fdlg.FilterIndex = 1;
    fdlg.RestoreDirectory = true;
}
private void btBrowse_Click(object sender, EventArgs e)
{
    if (fdlg.ShowDialog() == DialogResult.OK)
    {
        fdlg.InitialDirectory = fdlg.FileName.Remove(fdlg.FileName.LastIndexOf("\\"));// THIS LINE IS IMPORTENT

        tbGekozenBestand.Text = fdlg.FileName;
        tbVeranderNaamIn.Text = Path.GetDirectoryName(fdlg.FileName);
        f_sOudeLocatie = Path.GetDirectoryName(fdlg.FileName);
        f_sSourceFileName = fdlg.FileName;
        f_sDestFileName = Path.GetFileName( Path.GetDirectoryName(fdlg.FileName) ) + ".csv";
        btOpslaan.Enabled = true;
        tbVeranderNaamIn.ReadOnly = false;
    }
}
