Question

当我尝试以管理员身份启动“cmd.exe”时，它不会要求输入密码，我可以执行命令。

下面的代码工作正常，但它要求管理员密码。

有没有办法自动解决并在本地管理员帐户下运行？

string subCommand = @"dir";
        string subCommandArgs = @"c:\";
        string subCommandFinal = @"cmd /K \""" + subCommand.Replace(@"\", @"\\") + " " + subCommandArgs.Replace(@"\", @"\\") + @"\""";
        ProcessStartInfo procStartInfo = new ProcessStartInfo("runas.exe");
        procStartInfo.UseShellExecute = true;
        procStartInfo.CreateNoWindow = true;
        string finalArgs = @"/env /user:Administrator """ + subCommandFinal + @"""";
        procStartInfo.Arguments = finalArgs;
        using (System.Diagnostics.Process proc = new System.Diagnostics.Process())
        {
            proc.StartInfo = procStartInfo;
            proc.Start();
        }

启动程序时，您可以测试程序是否以管理员身份运行，如果不以管理员身份重新启动，则要求用户只按一次ok。

    void RestartIfNeeded() {
        if (!IsAdmin() {
            Process p= new Process {
                StartInfo = new ProcessStartInfo {
                    FileName = Process.GetCurrentProcess().MainModule.FileName,
                    Arguments = //parameters here,
                    //Following two lines make process start as admin
                    Verb = "runas";
                    UseShellExecute = true;
                }
            }
            p.Start();
            p.WaitForExit();
            p.Dispose();
            Enviroment.Exit(p.ExitCode)
        }
    }
    bool IsAdmin() {
            try {
                return new WindowsPrincipal(WindowsIdentity.GetCurrent()) 
                    .IsInRole(WindowsBuiltInRole.Administrator);
            }
            catch (Exception) {
                return false;
            }
        }

如果您的进程应在启动时启动，则可以使用Windows任务计划程序的“以最高权限运行”功能。

                public static bool InitalizeScheduledTask() {
string TaskName=//TaskName here;
                    XNamespace taskNamespace =
                        XNamespace.Get("http://schemas.microsoft.com/windows/2004/02/mit/task");
                    XElement taskContents = new XElement(taskNamespace + "Task", new XAttribute("version", "1.4"),
                        new XElement(taskNamespace + "RegistrationInfo",
                            new XElement(taskNamespace + "Date", DateTimeToWin32Format(DateTime.Now)),
                            new XElement(taskNamespace + "Author", WindowsIdentity.GetCurrent().Name),
                            new XElement(taskNamespace + "Description",
                                "[Description here] "),
                            new XElement(taskNamespace + "URI", $"\\{TaskName}")),
                        new XElement(taskNamespace + "Triggers",

                                new XElement(taskNamespace + "RunLevel", "HighestAvailable"))),

                            new XElement(taskNamespace + "AllowHardTerminate", false),
                            new XElement(taskNamespace + "StartWhenAvailable", false),
                            new XElement(taskNamespace + "RunOnlyIfNetworkAvailable", false),
                            new XElement(taskNamespace + "IdleSettings", new XElement(taskNamespace + "StopOnIdleEnd", true),
                                new XElement(taskNamespace + "RestartOnIdle", false)),

                            new XElement(taskNamespace + "Enabled", true), new XElement(taskNamespace + "Hidden", false),
                            new XElement(taskNamespace + "RunOnlyIfIdle", false),
                            new XElement(taskNamespace + "DisallowStartOnRemoteAppSession", false),
                            new XElement(taskNamespace + "UseUnifiedSchedulingEngine", true),
                            new XElement(taskNamespace + "WakeToRun", false),
                            new XElement(taskNamespace + "ExecutionTimeLimit", "PT0S"),
                            new XElement(taskNamespace + "Priority", 7)),
                        new XElement(taskNamespace + "Actions", new XAttribute("Context", "Author"),
                            new XElement(taskNamespace + "Exec",
                                new XElement(taskNamespace + "Command", Process.GetCurrentProcess().MainModule.FileName),
                                new XElement(taskNamespace + "Arguments",//Arguments ))));
                    string taskString = new XDocument(new XDeclaration("1.0", "UTF-16", null),
                        taskContents).ToString();
                string tempLocation = Path.Combine(Path.GetTempPath(),$"{TaskName}.xml");
                    File.WriteAllText(tempLocation, taskString);
/*Run Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.System), "SCHTASKS.exe") with the arguments $"/Create /XML \"{tempLocation}\" /TN {TaskName} /RP * /RU {Environment.UserName}"
I have no time to add that now, in that window you will need to enter your password and you have to be admin*/} 
    public static string DateTimeToWin32Format(DateTime toConvert) =>
                $"{toConvert.Year:0000}-{toConvert.Month:00}-{toConvert.Day:00}T{toConvert.Hour:00}:{toConvert.Minute:00}:{toConvert.Second:00}.{toConvert.Millisecond:000}0000";

如果您的程序从受保护的安装目录运行，请仅使用该功能。

有没有办法让程序不要求管理员密码？
