c# - 路径不是合法的 C# 表格

Question

我在以下行收到一条错误消息：“路径不是合法形式”：

fileSystemWatcher2.EnableRaisingEvents = true;

这是我的代码：

 private void Browse_file_Click(object sender, EventArgs e)
    {
        DialogResult resDialog = openFileDialog1.ShowDialog();
        if (resDialog == DialogResult.OK)
        {
            FileBrowseBox.Text = openFileDialog1.FileName;
        }


            fileSystemWatcher1.EnableRaisingEvents = false;  // Stop watching
            fileSystemWatcher1.IncludeSubdirectories = true;
            fileSystemWatcher1.Path = Path.GetDirectoryName(FileBrowseBox.Text);         // Text of textBox2 = Path of fileSystemWatcher2
            fileSystemWatcher1.EnableRaisingEvents = true;   // Begin watching

    }

    private void Browse_destination_Click(object sender, EventArgs e)
    {

        if (dlgOpenDir.ShowDialog() == DialogResult.OK)
        {
            fileSystemWatcher2.EnableRaisingEvents = false;  // Stop watching
            fileSystemWatcher2.IncludeSubdirectories = true;
            DestinationBox.Text = dlgOpenDir.SelectedPath;
            fileSystemWatcher2.Path = DestinationBox.Text;
            fileSystemWatcher2.EnableRaisingEvents = true;   // Begin watching
        }
    }

这是 DestinationBox.Text

我需要它来向它传输文件，但我也想在其中使用 filewatch 会发生什么我用 FileSystemWatcher2 解决了它，但在 FileSystemWatcher1 仍然给我一个错误

您没有使用dlgOpenDir（大概是 a FolderBrowserDialog）选择的路径。试试这个：

if (dlgOpenDir.ShowDialog() == DialogResult.OK)
{
    fileSystemWatcher2.EnableRaisingEvents = false;  // Stop watching
    fileSystemWatcher2.IncludeSubdirectories = true;
    fileSystemWatcher2.Path = dlgOpenDir.SelectedPath;
    fileSystemWatcher2.EnableRaisingEvents = true;   // Begin watching
}

或者，如果你真的想显示正在被监视的文件夹，你可以这样做：

if (dlgOpenDir.ShowDialog() == DialogResult.OK)
{
    fileSystemWatcher2.EnableRaisingEvents = false;  // Stop watching
    fileSystemWatcher2.IncludeSubdirectories = true;
    DestinationBox.Text = dlgOpenDir.SelectedPath;
    fileSystemWatcher2.Path = DestinationBox.Text;
    fileSystemWatcher2.EnableRaisingEvents = true;   // Begin watching
}
