Closing form from another thread
提问by Marek
I have got this code which runs an .exe
我有这个代码运行 .exe
string openEXE = @"C:\Users\marek\Documents\Visual Studio 2012\Projects\tours\tours\bin\Debug\netpokl.exe";
Process b = Process.Start(openEXE);
b.EnableRaisingEvents = true;
b.Exited += (netpokl_Closed);
And when it closes it calls method netpokl_Closed. The issue is when I insert into netpokl_Closed command- this.Close()this exception rises: Cross-thread operation not valid: Control accessed from a thread other than the thread it was created on
当它关闭时，它调用方法 netpokl_Closed。问题是当我insert into netpokl_Closed command-this.Close()这个异常出现时：Cross-thread operation not valid: Control accessed from a thread other than the thread it was created on
How can I fix it ? Thank you for your time and answers.
我该如何解决？感谢您的时间和答案。

You are getting the exception because you are trying to close the form from a thread other than on what it was created on. This is not allowed.
您收到异常是因为您试图从线程关闭表单而不是在创建表单的线程上关闭表单。这是不允许的。
do it like this
像这样做
this.Invoke((MethodInvoker) delegate
{
// close the form on the forms thread
this.Close();
});

You can close your form using Delegate
您可以使用关闭表单 Delegate
public delegate void CloseDelagate();
Form1.Invoke(new CloseDelegate(Form2.Close));

When a thread other than the creating thread of a control tries to access one of that control's methods or properties, it often leads to unpredictable results. A common invalid thread activity is a call on the wrong thread that accesses the control's Handle property
当控件的创建线程以外的线程尝试访问该控件的方法或属性之一时，通常会导致不可预测的结果。一个常见的无效线程活动是对访问控件的 Handle 属性的错误线程的调用
Gets or sets a value indicating whether to catch calls on the wrong thread that access a control's Handle property when an application is being debugged.
