如何在不同的线程上更改窗体的窗口状态？
有谁知道如何从另一个线程更改表单的窗口状态？这是我正在使用的代码：
private void button4_Click(object sender, EventArgs e)
{
string pathe = label1.Text;
string name = Path.GetFileName(pathe);
pathe = pathe.Replace(name, "");
string runpath = label2.Text;
Process process;
process = new Process();
process.EnableRaisingEvents = true;
process.Exited += new System.EventHandler(process_Exited);
process.StartInfo.FileName = @runpath;
process.StartInfo.WorkingDirectory = @pathe;
process.Start();
WindowState = FormWindowState.Minimized;
}
private void process_Exited(object sender, EventArgs e)
{
this.WindowState = FormWindowState.Normal;
}
它的目的是运行一个程序并最小化，然后在程序关闭后返回到正常状态。尽管我收到此错误“跨线程操作无效：从创建它的线程以外的线程访问控制'Form1'”。知道如何让它发挥作用吗？
Does anyone know how I can change the window state of a form, from another thread? This is the code I'm using:
private void button4_Click(object sender, EventArgs e)
{
string pathe = label1.Text;
string name = Path.GetFileName(pathe);
pathe = pathe.Replace(name, "");
string runpath = label2.Text;
Process process;
process = new Process();
process.EnableRaisingEvents = true;
process.Exited += new System.EventHandler(process_Exited);
process.StartInfo.FileName = @runpath;
process.StartInfo.WorkingDirectory = @pathe;
process.Start();
WindowState = FormWindowState.Minimized;
}
private void process_Exited(object sender, EventArgs e)
{
this.WindowState = FormWindowState.Normal;
}
It's meant to run a program and minimize, then return to the normal state once the program has closed. Although I get this error "Cross-thread operation not valid: Control 'Form1' accessed from a thread other than the thread it was created on." Any idea how to get this to work?

这适用于 .NET 3.5：
或 2.0：
This will work in .NET 3.5:
Or 2.0:
只需在 StackOverflow“跨线程操作无效”或 Google 中搜索此字符串即可。拜托，别那么懒。
Just search this string in StackOverflow "Cross-thread operation not valid" or Google. Please, don't be that lazy.
请参阅 Invoke() 和 BeginInvoke() 之间的区别地点。 “选择的”答案很好地解释了你应该做什么。
长话短说，您想要不同的线程而不是完全创建一个新进程（或者您不太可能想要这样），并且您可能想要使用
Invoke()而不是BeginInvoke()这是异步的。See What’s the difference between Invoke() and BeginInvoke() on this site. The "chosen" answer gives a good explanation of what you're supposed to do.
Long story short, you want different THREADS not making a new process entirely (or highly unlikely you want that), and you probably want to use
Invoke()and notBeginInvoke()which is asynchronous.将此行代码添加到 Click 事件处理程序中：
Add this line of code to the Click event handler:
这将解决您的问题，将其添加到
form_load事件中this will solve your problem add it in the
form_loadevent
