您可以使用后台工作程序 ^ ]

You can use background worker http://msdn.microsoft.com/en-us/library/cc221403(v=vs.95).aspx[^]

1.当心memoryoutofbounds异常.
2.我认为您需要查看BackgroundWorker类.
3.对于启动画面"，您可以创建一个对话框并删除所有窗口标题和控制按钮(关闭，最小化...).将大小设置为固定.在该对话框上，添加一个图片框(或类似控件)并将其最大化(在winform基座填充中).开始加载时，请在启动屏幕对话框上调用Show或ShowDialog方法，加载完成后调用Close方法.

希望这会有所帮助.

1. watch out for memoryoutofbounds exceptions.
2. I think you need to look at the BackgroundWorker class.
3. For the "Splashscreen" you can create a dialog and remove all window titles and control buttons (close, minimize, ...) Set the size to fixed. On that dialog you add a picturebox (or similar control) and maximize it (in winform dock fill). When you start loading you call Show or ShowDialog method on your splashscreen dialog and the Close method when loading is finished.

Hope this helps.
