.net如何在中把form作为控件添加到Controls中

 方法如下：

其中_cstCatAssignmentMgr为form类实例，将这个实例添加到一个panel中：

this._cstCatAssignmentMgr.TopLevel = false;

this._cstCatAssignmentMgr.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;
this._cstCatAssignmentMgr.Dock = DockStyle.Fill;
this._cstCatAssignmentMgr.Show();
this.panel1.Controls.Add(this._cstCatAssignmentMgr);
this._cstCatAssignmentMgr.Show();
