c# - 打开文件对话框。“指定目录对话框”怎么样？

Question

在文件路径字段上，我想捕获目录路径，例如：

textbox1.Text = directory path

任何人？

Answer 1

如果希望用户选择文件夹，可以使用 FolderBrowserDialog 类。

http://msdn.microsoft.com/en-us/library/system.windows.forms.folderbrowserdialog.aspx

DialogResult result = folderBrowserDialog1.ShowDialog();
if (result.Equals(get_DialogResult().OK)) {
    textbox1.Text = folderBrowserDialog1.get_SelectedPath();
}

如果您只想从完整路径中获取目录，您可以这样做：

textbox1.Text = Path.GetDirectoryName(@"c:\windows\temp\myfile.txt");

这会将文本属性设置为“c:\windows\temp\”

Answer 2

好吧，我正在使用 VS 2008 SP1。这就是我所需要的：

private void button1_Click(object sender, EventArgs e)
{
    FolderBrowserDialog profilePath = new FolderBrowserDialog();

    if (profilePath.ShowDialog() == DialogResult.OK)        
    {
        profilePathTextBox.Text = profilePath.SelectedPath;
    }
    else
    {
        profilePathTextBox.Text = "Please Specify The Profile Path";
    }
}

If you don't want a terrible, non-user friendly dialog*, try Ookii.Dialogs or see other answers to How do you configure an OpenFileDialog to select folders?. The only downside I see to Ookii is that it requires .NET 4 Full, not just Client Profile. But the source is included in the download, so I'm going to work on that. Too bad the license isn't LGPL or similar...
