在win7上编译成功并且运行也没有错，安装到windows xp上后报错！根据错误日志，可以知道是在利用反射机制创建窗体的时候出错！
程序运行到第二行时出错，
Type t = Type.GetType(frmfullname);
第二行 Object obj = (Object)Activator.CreateInstance(t);
OfficeForm oForm = (OfficeForm)obj;
oForm.MdiParent = this;
oForm.Text = frmtext;
oForm.Dock = System.Windows.Forms.DockStyle.Fill;
oForm.Show();
错误日志是：

我思考了两天，也查了两天的资料，感觉是在windows xp 上运用反射机制出错，可能是少某些控件！求大神指导！
