问题描述
我尝试使用C#。例改变背景:
I try to change the background using C#.Example:
[DllImport("user32.dll", CharSet = CharSet.Auto)]
private static extern Int32 SystemParametersInfo(UInt32 uiAction, UInt32
uiParam, String pvParam, UInt32 fWinIni);
private static UInt32 SPI_SETDESKWALLPAPER = 20;
private static UInt32 SPIF_UPDATEINIFILE = 0x1;
然后
And then
SystemParametersInfo(SPI_SETDESKWALLPAPER, 1, @"C:\background.bmp", SPIF_UPDATEINIFILE);
}
但它不工作...帮助?
But it doesn't work...Help?
推荐答案
pvParam
应该是一个本地文件。它不会对网址的工作......
pvParam
should be a local file. It will not work for urls...
首先下载的图像,然后给 SystemParametersInfo
本地路径法
First download the image, then give its local path to SystemParametersInfo
method.
var filename = "4.jpg";
new WebClient().DownloadFile("http://www.scottgames.com/4.jpg", filename);
SystemParametersInfo(SPI_SETDESKWALLPAPER, 1, filename, SPIF_UPDATEINIFILE);
