回复 楼主 mmmmjyie
每次关闭后重新new一个窗体对象试试。我是把一个窗体附着在另一个窗体的panel上显示的。
示例代码:
FormBroad newFormBroad = new FormBroad();//创建图片窗体新实例,用于对显示在主窗体对图片窗体进行各种设置和操作
newFormBroad.NewFrmMain = this;
newFormBroad.Dock = DockStyle.Fill;
newFormBroad.TopLevel = false;
this.panel3.Controls.Add(newFormBroad);
newFormBroad.Parent = this.panel3;
newFormBroad.Show();
