C# 表单不会在 FormClosing 事件上关闭

将以下代码添加到我的代码隐藏后，我的表单不会关闭。

private void Form1_FormClosing(object sender, FormClosingEventArgs e) {
    MyThreadingObj.Dispose();
}

原文

After I added the following code to my code-behind, my form doesn't get closed.

private void Form1_FormClosing(object sender, FormClosingEventArgs e) {
    MyThreadingObj.Dispose();
}

听起来添加上述代码会阻止您的 Form 关闭。如果是这样，那么最可能的原因是 MyTHreadingObj.Dispose() 语句引发异常。尝试将语句包装在 try/catch 中，看看是否是这种情况

try {
  MyThreadingObj.Dispose();
} catch ( Exception e ) { 
  Console.WriteLine(e);
}

It sounds like adding the above code prevents your Form from closing. If so then the most likely cause is that the MyTHreadingObj.Dispose() statement is throwing an exception. Try wrapping the statement in a try/catch and seeing if this is the case

try {
  MyThreadingObj.Dispose();
} catch ( Exception e ) { 
  Console.WriteLine(e);
}
