Windows 7和Vista UAC-以编程方式在C＃中请求提升
问题描述：
我有一个程序，在极少数情况下只需要提升管理员权限，所以我不想将清单设置为需要永久提升权限。
I have a program that only requires elevation to Admin on very rare occasions so I do not want to set-up my manifest to require permanent elevation.
如何我以编程方式仅在需要时请求海拔？
How can I Programmatically request elevation only when I need it?
我正在使用C＃
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;
}
