我正在写一个C#程序，要推出我工作的实验室。程序是创建一个本地管理员帐户(itadmin)，设置密码，设置密码永不过期，并将帐户添加到本地管理员组。该程序创建了新的用户帐户并正确设置了所有内容，但是当它尝试将其添加到管理员组时，我得到了一个非常不起眼的异常。我首先添加到组是否正确？我错过了什么？

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.DirectoryServices;

namespace CreateITAdmin
{
    class Program
    {
        static void Main(string[] args)
        {
            try
            {
                string userName = "itadmin";
                string userPassword = "password";

                Console.WriteLine("Building System Information");
                DirectoryEntry localMachine = new DirectoryEntry("WinNT://.,computer");
                DirectoryEntry newUser = localMachine.Children.Add(userName, "user");
                DirectoryEntry admGroup = new DirectoryEntry("WinNT://./Administrators,group");

                Console.WriteLine("Building User Information");
                newUser.Properties["FullName"].Value = "IT Administrative User";
                newUser.Invoke("Put", new object[] { "UserFlags", 0x10000 });

                Console.WriteLine("Setting User Password");
                newUser.Invoke("SetPassword", new object[] { userPassword });

                newUser.CommitChanges();

                Console.WriteLine("Adding itadmin to Administrators Group");
                admGroup.Invoke("Add", "WinNT://./" + newUser);

                Console.WriteLine("Cleaning Up");
                localMachine.Close();
                newUser.Close();
                admGroup.Close();
            }
            catch (System.DirectoryServices.DirectoryServicesCOMException E)
            {
                Console.WriteLine(E.Message.ToString());
                Console.ReadLine();
            }
            catch (System.Runtime.InteropServices.COMException E)
            {
                Console.WriteLine(E.Message.ToString());
                Console.ReadLine();
            }
            catch (System.Reflection.TargetInvocationException E)
            {
                Console.WriteLine(E.Message.ToString());
                Console.ReadLine();
            }
            catch (Exception E)
            {
                Console.WriteLine(E.Message.ToString());
                Console.ReadLine();
            }

            Console.WriteLine();
            Console.WriteLine("Press Any Key to Continue");
            Console.ReadLine();
            return;
        }
    }
}

代码输出如下:

Building System Information
Building User Information
Setting User Password
Adding itadmin to Administrators Group
Exception has been thrown by the target of an invocation.

如有任何见解，我们将不胜感激。

更新 1: 在@Grumbler85 的帮助下，异常(exception)情况如下:

System.Reflection.TargetInvocationException: Exception has been thrown by the target 
of an invocation. ---> System.Runtime.InteropServices.COMException: A member could not
be added to or removed from the local group because the member does not exist. --- End
of inner exception stacktrace --- at System.DirectoryServices.DirectoryEntry.Invoke
(String methodName,Object[]args) at CreateITAdmin.Program.Main(String[]args)in 
H:\code\CS\CreateITAdmin\CreateITAdmin\Program.cs:line 37

另外，在@Grumbler85 的帮助下，我一直致力于将库使用更新为 System.DirectoryServices.AccountManagement。它似乎更容易使用，也更直接。随着我的进步，会有更多更新/细节。

更新 2: 我知道这是一个快速跟进，但我能够完成对新命名空间的更新。在定义机器时遇到一些小问题后，我能够成功地创建用户、设置密码、将密码更新为永不过期，并将用户添加到管理员组。感谢@Grumbler85 对新命名空间的更新。新代码如下:

最佳答案

对于 Update 3(多语言支持)

请使用内置标识符 --> “Well Known SIDs”用于内置帐户或组:

var sAdministrators = new SecurityIdentifier(WellKnownSidType.BuiltinAdministratorsSid , null).Translate(typeof(NTAccount)).Value;

groupPrincipal = GroupPrincipal.FindByIdentity(systemContext, IdentityType.Name, sAdministrators.ToString());

而不是:..... FindByIdentity(systemContext, "Administrators");

因为如果你想在“世界范围内”使用它并且在 engl 之外使用它。 world 你会得到一个错误。示例:德国使用“VORDEFINIERT\Administratoren”作为名称。
