怎样做到让程序窗口始终显示在桌面最上层,即始终掩盖在其他打开的窗口之

1、可以使用ShowDialog()。ShowDialog()将其置于程序最顶层,而且不能使用当前程序的其它窗体。2、可以设置Form.TopMost 属性为true，关于此属性的介绍：Form.TopMost 属性获取或设置一个值，指示该窗体是否应显示为最顶层窗体。命名空间:System.Windows.Forms程序集:System.Windows.Forms（在 system.windows.forms.dll 中）参考代码与注释：private void CreateMyTopMostForm(){ // Create lower form to display. Form bottomForm = new Form(); // Display the lower form Maximized to demonstrate effect of TopMost property. bottomForm.WindowState = FormWindowState.Maximized; // Display the bottom form. bottomForm.Show(); // Create the top most form. Form topMostForm = new Form(); // Set the size of the form larger than the default size. topMostForm.Size = new Size(300,300); // Set the position of the top most form to center of screen. topMostForm.StartPosition = FormStartPosition.CenterScreen; // Display the form as top most form. topMostForm.TopMost = true; topMostForm.Show();}两者二选一即可。
