各位

當我Client 按 connect 的時候我的Server 出現這個問題，請問怎樣解決

這是 Server

[STAThread]
static void Main()
{

}
}
}

复制代码

它說這兒有問題

lbClients.Items.Add(c);

复制代码

錯誤信息
Cross-thread operation not valid: Control 'lbClients' accessed from a thread other than the thread it was created on.

我該怎樣解決

因为是 threading, UI 是在另外个thread，你必须用 Invoke Method.
上网查 C# Threading Invoke.

有两个了，

一个充大头鬼
说会什么会什么的
我给我的 VS 他，拿走其中的一段
compile 问他 bug 在哪里
找不出来

另外几个是 HTML javascripts 罢了

我不4是没请，我丢给了我师父罢了
我师父也是很厉害的 programmer
他们住的地方比较近我师傅
跟过我师傅的出来都是超厉害的
包括本人
