C# .NET 清除 IE 临时文件

by ·0评论

利用 shell32 API清除IE缓存。好处是调用系统原生清理，保证效果，不好的就是会弹出窗口，影响用户体验。

public class ShellUtil
{
	[DllImport("shell32.dll")]
	public static extern IntPtr ShellExecute(IntPtr hwnd, string lpOperation, string lpFile, string lpParameters, string lpDirectory, ShowCommands nShowCmd);
}

public enum ShowCommands : int
{
	SW_HIDE = 0,
	SW_SHOWNORMAL = 1,
	SW_NORMAL = 1,
	SW_SHOWMINIMIZED = 2,
	SW_SHOWMAXIMIZED = 3,
	SW_MAXIMIZE = 3,
	SW_SHOWNOACTIVATE = 4,
	SW_SHOW = 5,
	SW_MINIMIZE = 6,
	SW_SHOWMINNOACTIVE = 7,
	SW_SHOWNA = 8,
	SW_RESTORE = 9,
	SW_SHOWDEFAULT = 10,
	SW_FORCEMINIMIZE = 11,
	SW_MAX = 11
}
