folderbrowserdialog selectedpath 不返回任何值

Question

private void button3_Click(object sender, EventArgs e)
{
    FolderBrowserDialog folderfinder = new FolderBrowserDialog();
    folderfinder.Description = "Select Folder";
    folderfinder.RootFolder = Environment.SpecialFolder.MyComputer;
    folderfinder.ShowNewFolderButton = false;

    Console.Write(folderfinder.SelectedPath);
}

以下代码始终为选定路径返回“”。有人看到这里有什么问题吗？我用谷歌搜索了一下，没有人提到 selectedpath 没有返回值的问题。

Answer 1

您应该显示对话框 (msdn)：

if (folderfinder.ShowDialog() == DialogResult.OK)
{
    Console.Write(folderfinder.SelectedPath);
}
