Windows 7和Vista UAC-以编程方式在C#中请求提升
我有一个程序,在极少数情况下只需要提升管理员权限,因此我不想将清单设置为需要永久提升。
如何仅在需要时以编程方式请求海拔?
我正在使用C#
回答:
WindowsPrincipal pricipal = new WindowsPrincipal(WindowsIdentity.GetCurrent());bool hasAdministrativeRight = pricipal.IsInRole(WindowsBuiltInRole.Administrator);
if (!hasAdministrativeRight)
{
RunElevated(Application.ExecutablePath);
this.Close();
Application.Exit();
}
private static bool RunElevated(string fileName)
{
//MessageBox.Show("Run: " + fileName);
ProcessStartInfo processInfo = new ProcessStartInfo();
processInfo.Verb = "runas";
processInfo.FileName = fileName;
try
{
Process.Start(processInfo);
return true;
}
catch (Win32Exception)
{
//Do nothing. Probably the user canceled the UAC window
}
return false;
}
