【winform】在某个线程上创建的控件不能成为在另一个线程上创建的控件的父级

Question

我的代码如下void load()
{
    Thread receiveThread = new Thread(ReceiveMessage);
    receiveThread.Start();
}
private void ReceiveMessage()
{
    while (true)
            {
                try
                {
                    byte[] receiveBytes = receiveUpdClient.Receive(ref remoteIpEndPoint);                    
                    string get = Encoding.Unicode.GetString(receiveBytes);
                    if (get == "head")
                        {
                            PictureBox p = new PictureBox();
                            p.Image = Properties.Resources.head;
                            p.SizeMode = PictureBoxSizeMode.StretchImage;
                            panel1.Controls.Add(p);//这里提示标题错误
                         }
                 }
                 catch(Exception e)
                {
                    string x = e.Message;
                    break;
                }
           }
}
求问我该怎么改？谢谢！

Answer 1

UI线程独占,不能直接怎么写,用invoke

Answer 2

不知道你说的是不是这个 How to: Make Thread-Safe Calls to Windows Forms Controlshttp://msdn.microsoft.com/en-us/library/ms171728.aspx?cs-save-lang=1&cs-lang=csharp#code-snippet-1

Answer 3

panel1.Invoke((DummyDelegate)delegate() {
 panel1.Controls.Add(p);}); public delegate void DummyDelegate();这样试试

Answer 4

或者试试：
this.Invoke((DummyDelegate)delegate() {PictureBox p = new PictureBox();
                            p.Image = Properties.Resources.head;
                            p.SizeMode = PictureBoxSizeMode.StretchImage;
                            panel1.Controls.Add(p);<span style="color: #FF0000;">
});
public delegate void DummyDelegate();
