受一位开网吧的朋友委托帮他的网吧做了一个重建图标缓存的小程序，通过调用API完成。

[DllImport("User32.dll", EntryPoint = "SendMessage")]
private static extern int SendMessage(IntPtr hWnd,int Msg,int wParam,int lParam);

public const int WM_SETTINGCHANGE = 26;
public const int HWND_BROADCAST = 65535;

static void Main(string[] args)
{
      int value = Convert.ToInt32(Registry.GetValue(@"HKEY_CURRENT_USER\Control Panel\Desktop\WindowMetrics", "Shell Icon Size", -1).ToString());
      Registry.SetValue(@"HKEY_CURRENT_USER\Control Panel\Desktop\WindowMetrics", "Shell Icon Size", value - 1, RegistryValueKind.String);
      SendMessage(new IntPtr(HWND_BROADCAST), WM_SETTINGCHANGE, 0, 0);
      Registry.SetValue(@"HKEY_CURRENT_USER\Control Panel\Desktop\WindowMetrics", "Shell Icon Size", value, RegistryValueKind.String);
      SendMessage(new IntPtr(HWND_BROADCAST), WM_SETTINGCHANGE, 0, 0);
}
