当我尝试运行这个应用程序时,它说:"路径不是合法的形式。"这是一个警告,它说"fileSystemWatcher1"有问题。inclesubdirectories = true;"当我点击浏览时。当我点击浏览第二个文件观察者它做完全相同的。(我有2个浏览按钮来观看2个目录)我给了filewatchers没有起始路径,但当我给他们一个起始路径时,它工作了。我不想那样。请帮帮我。

只是一个大胆的猜测,但也许您需要在更改IncludeSubdirectories
之前将EnableRaisingEvents
设置为false,而Path
呢?这样的:
private void button2_Click(object sender, EventArgs e)
{
if (dlgOpenDir.ShowDialog() == DialogResult.OK)
{
fileSystemWatcher1.EnableRaisingEvents = false; // Stop watching
fileSystemWatcher1.IncludeSubdirectories = true;
fileSystemWatcher1.Path = dlgOpenDir.SelectedPath;
textBox1.Text = dlgOpenDir.SelectedPath;
fileSystemWatcher1.EnableRaisingEvents = true; // Begin watching
}
}

把你的代码放在你在try块中传递路径的地方,并在catch块中捕获异常,像这样
try
{
// Your code goes here
}
catch(Exception ex)
{
// If exception raise compiler comes here..
}
