MDI 窗体中打开子窗体的函数。

代码如下: 程序代码   private void OpenChild(string Frmnamespace, string ChildTypeName)         {             int ret = 0;             foreach (Form frm in MdiChildren)             {                 if (frm.GetType().Name == ChildTypeName)                 {                     frm.Activate();                     ret = 1;                     break;                 }             }             if (0 == ret)             {                 string className = Frmnamespace + "." + ChildTypeName;                 Form Instance = (Form) Assembly.Load(Frmnamespace).CreateInstance(className);                 Instance.MdiParent = this;                 Instance.Show();             }         } 传入一个窗体，先检查这个窗体是不是有副本，如果有副本，则置前，否则新创建并显示. 使用方法： 程序代码 private void LbtUserManager_ItemClick(object sender, ItemClickEventArgs e)         {             OpenChild("OuterRingRoad", "frmUserManager");         }         private void MenuUserPopdemod_ItemClick(object sender, ItemClickEventArgs e)         {             OpenChild("OuterRingRoad", "frmUserPopdemod");         }         private void MenuCurrentTimeData_ItemClick(object sender, ItemClickEventArgs e)         {             OpenChild("ORRTLB", "frmNowVDIInfo");         }         private void MenuCarCheckConfig_ItemClick(object sender, ItemClickEventArgs e)         {             OpenChild("ORRTLB", "frmVDISetting");         }
