C # obtain the desktop wallpaper image path (Desktop Wallpaper)

Use the Windows API to obtain the actual path of the desktop wallpaper. The systemparametersinfo API is used. This API provides a wide range of functions, and the wallpaper operation is just an example.

Using system. runtime. interopservices;

[Dllimport ("user32.dll", charset = charset. auto, setlasterror = true)] Static extern bool systemparametersinfo (uint uaction, uint uparam, stringbuilder lpvparam, uint init); const uint spi_get1_wallpaper = 0x0073;

Stringbuilder wallpaperpath = new stringbuilder (200); If (systemparametersinfo (spi_get1_wallpaper, 200, wallpaperpath, 0) {MessageBox. Show (wallpaperpath. tostring ());}

 

Done!
