當 flowlayoutpanel 控件在 c# 中清除時，創建 window 句柄時出錯？

Question

如果我發送另一個請求，winform 長時間打開時我會遇到一個問題，錯誤是為 flowlayout 面板控制清除創建 window 句柄：

 flw.Invoke(new Action(() => flw.Controls.Clear()));

錯誤：錯誤 OnExampleDTOReceived：創建 window 句柄時出錯。-->-->System.ComponentModel.Win32Exception：創建 window 句柄時出錯。 at System.Windows.Forms.Control.MarshaledInvoke(Control caller, Delegate method, Object[] args, Boolean synchronous) at System.Windows.Forms.Control.Invoke(Delegate method, Object[] args) at PrxCustScr.Sockets.Listener .EndTrx(String data, FlowLayoutPanel flw) in \Source\Workspaces\TestApplications\PrxCustScr\PrxCustScr\Sockets\Listener.cs: PrxCustScr.Sockets.Listener.OnExampleDTOReceived(String message) 中的第 689 行\PrxCustScr\Sockets\Listener.cs:line 273--> at System.Windows.Forms.Control.MarshaledInvoke(Control caller, Delegate method, Object[] args, Boolean synchronous) at System.Windows.Forms.Control.Invoke( D elegate method, Object[] args) at PrxCustScr.Sockets.Listener.EndTrx(String data, FlowLayoutPanel flw) in \Source\Workspaces\TestApplications\PrxCustScr\PrxCustScr\Sockets\Listener.cs:line 689 at PrxCustScr.Sockets.Listener. \Source\Workspaces\TestApplications\PrxCustScr\PrxCustScr\Sockets\Listener.cs 中的 OnExampleDTOReceived（字符串消息）：第 273 行

我怎么解決這個問題？

我用這段代碼解決了：

for(int i = flowlayoutpanel1.Controls.Count-1; i >= 0; --i)
{ 
   var ctl = flowlayoutpanel1.Controls[i];
    ctl.Dispose();
}
