加急！！！C#一， 如何获取VISTA管理员权限，以避免UAC弹出窗口；二，XP＆vista下C＃中如何创建、取消、删除、还原 系统还原点？
C#中:1. 本人在开发一个ASSEMBLY，这个ASSEMBLY是一个ActionEngine,在里面需要调用几个Action的Handler，但是在Vista下，(UAC)是需要一个权限的提升的（elevation),为了避免多次弹出提示窗口，我想让本ActionEngine的Assembly 获取管理员权限。但我不知道该如何实现？
public ExecuteActionsResult ExecuteActions
(
parameters...
)
{
//parameters checking lines....
TOKEN_ELEVATION_TYPE elevationType;
elevationType = GetTokenElevationType();
ExecuteActionsResult result = ExecuteActionsResult.None;
bool isVistaOrHigher = false;
bool isSecondEngineProcess = false;
bool isElevated = false;
bool processContinue = true;
// OS version is vista or higher
if (Environment.OSVersion.Version.Major < 6)
{
isVistaOrHigher = true;
}
if (isVistaOrHigher && elevationType == TOKEN_ELEVATION_TYPE.TokenElevationTypeFull)
{
if (applicationNameCopy.StartsWith(secondActionsEngineInVista))
{
applicationNameCopy = applicationNameCopy.Substring(secondActionsEngineInVista.Length);
isSecondEngineProcess = true;
}
}
//check admin flag
if (isVistaOrHigher)
{
elevationType = GetTokenElevationType();
switch (elevationType)
{
case TOKEN_ELEVATION_TYPE.TokenElevationTypeDefault: //TokenElevationTypeDefault - User is not using a split token
isVistaOrHigher = false;
break;
case TOKEN_ELEVATION_TYPE.TokenElevationTypeFull: //TokenElevationTypeFull - User has a split token, and the process is running elevated
if (isSecondEngineProcess)
{
isElevated = true;
}
else
{
isVistaOrHigher = false;
}
break;
//TokenElevationTypeLimited - User has a split token, but the process is not running elevated
case TOKEN_ELEVATION_TYPE.TokenElevationTypeLimited:
需要帮助的部分－－开始－－
该如何写代码创建第二个ActionEngine.ExecuteActions()?并获取管理员权限？
//ProcessStartInfo startInfo = new ProcessStartInfo();
//startInfo.UseShellExecute = true;
//startInfo.WorkingDirectory = Environment.CurrentDirectory;
//startInfo.FileName = Application.ExecutablePath;
//startInfo.Verb = "runas";
//try
//{
// Process p = Process.Start(startInfo);
//}
//catch (System.ComponentModel.Win32Exception ex)
//{
// return; //If cancelled, do nothing
//}
SolutionsEngine secondSolutionsEngine = new SolutionsEngine();
secondSolutionsEngine.ExecuteActions(rha, secondActionsEngineInVista + applicationNameCopy, device, solution);
需要帮助的部分－－结束－－
break;
}
}
}
//继续执行各Action...
if (!(isVista && isElevated )) processContinue =false;
if (processContinue )
{
actionResult = ExecuteAction(rha, applicationName, device, solution, st as Action);
OnActionsExecuted(aser);
}
// return result lines...
}
2. C#中如何创建、取消、删除、还原 系统的还原点？
下面是我做测试用的一个小东东，是可以创建系统还原点的，但是取消，删除和还原这些还原点却做不到，希望大侠帮一下忙。

[img=http://asp.daqing.net/baby/vote.asp?id=20][/img] --------------------编程问答-------------------- 谢谢帮顶！
这两个问题我查遍了NNNNNNNNNN多网站和MSDN也查不到C＃的代码。
希望高手帮忙解决！
--------------------编程问答-------------------- 涉及到新Windows系统的现成C#代码...
应该是比较少的...
^o^ --------------------编程问答-------------------- 确实如此，希望高手能进来帮忙解决一下问题。现在我尝试过的方法就差直接给微软工程师去邮件了 :(
顶上去，高手请赐教！ --------------------编程问答-------------------- 这个...
除了关了UAC估计没别的办法.
vista下一个已经获得管理员权限的进程所创建的子进程将自动获得管理员权限.
LZ不妨从这方面下手.这样的话应该只用弹出一次UAC的窗口. --------------------编程问答-------------------- 谢谢楼上的，UAC估计不太可能都关掉的，因为我们没办法控制所有的CLIENT。
继续顶! --------------------编程问答-------------------- 我也想要知道呀 --------------------编程问答-------------------- 期待答案 ！！ --------------------编程问答-------------------- 应该是 在 控制台 呼叫一些程序，
或者 WMI 搞搞破坏
用 以什么身份来运行之类的
--------------------编程问答-------------------- 这个只有表示关注了。、、、
--------------------编程问答--------------------
不可能来隐藏系统uac权限.无解!就是为了安全才设置这个的.
补充：.NET技术 , C#
