我使用.NET 3.5创建了简单的窗体。该应用程序在Windows CE设备上运行。

当我在我的应用程序中显示此表单时，灰色线条覆盖表单的顶部cca 20像素。

表单上没有显示灰色面板的面板，标签，texbox或其他任何内容。它不是一个控件，它应该是隐形的或类似的东西 - 那里什么都没有。我想不出任何可能导致这种情况的事情。

Answer 1

表单自动添加System.Windows.Forms.MainMenu。在设计器中将其删除（您将在窗体设计器下方的灰色区域中找到它，其中所有不可见的控件，如定时器，串行端口等）。

您也可以在发布的设计师代码中看到它：

private void InitializeComponent()
{
    this.mainMenu1 = new System.Windows.Forms.MainMenu();
    ...

Windows CE在表单顶部显示不存在的面板
