如何在不同的线程上更改Form的窗口状态？

Question

有谁知道如何从另一个线程更改窗体的窗口状态？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;
    }

这意味着运行程序并最小化,然后在程序关闭后返回正常状态.虽然我收到此错误"跨线程操作无效:控件'Form1'从其创建的线程以外的线程访问." 知道如何让这个工作吗？

这将适用于.NET 3.5:

Invoke(new Action(() => { this.WindowState = FormWindowState.Normal; }));

或2.0:

Invoke(new MethodInvoker(delegate { this.WindowState = FormWindowState.Normal; }));
