在一个窗体中加载其它窗体形成MDI多窗体容器

private void loadwindow(string formname) { if (loadedWindow != null && loadedWindow.Name == formname) { return; } if (loadedWindow != null) { loadedWindow.Close(); loadedWindow.Dispose(); } loadedWindow = (Form)Activator.CreateInstance(Type.GetType("抽取."+ formname)); loadedWindow.TopLevel = false; loadedWindow.FormBorderStyle = FormBorderStyle.None; loadedWindow.Width = this.panel2.Width; loadedWindow.Height = this.panel2.Height; this.panel2.Controls.Add(loadedWindow); loadedWindow.Show(); }
