在C＃中更改本地管理员密码 [英] Change local administrator password in C#

问题描述

我要寻找一种方式来在Windows更改本地用户帐户（本地管理员）的密码（XP在这种情况下）的机器。我已阅读 $ C $的CProject文章了解一种方式来做到这一点，不过这似乎并不干净。

我可以看到，这是可能的WMI 做的，所以这可能是答案，但我无法弄清楚如何使用WinNT WMI命名空间的ManagementObject。当我尝试以下code，它抛出一个无效参数的异常。

 公共静态无效ResetPassword（字符串计算机名，用户名字符串，字符串NEWPASSWORD）{
            的ManagementObject的ManagementObject =新的ManagementObject（WINNT：//+计算机名+/+用户名）; //抛出异常
            [对象] newpasswordObj = {}新密码;
            managementObject.InvokeMethod（SetPassword，newpasswordObj）;
}
 

有没有更好的方法来做到这一点？ （我使用.NET 3.5）

编辑：感谢伊利指着我在正确的方向。这里是code我最终使用：

 公共静态无效ResetPassword（字符串计算机名，用户名字符串，字符串NEWPASSWORD）{
        的DirectoryEntry的DirectoryEntry =新的DirectoryEntry（的String.Format（WINNT：// {0} / {1}，计算机名，用户名））;
        directoryEntry.Invoke（SetPassword新密码）;
}
 

解决方案

尝试的DirectoryEntry 类，而不是的ManagementObject 类。

I am looking for a way to change the password of a local user account (local Administrator) on a Windows (XP in this case) machine. I have read the CodeProject article about one way to do this, but this just doesn't seem 'clean'.

I can see that this is possible to do with WMI, so that might be the answer, but I can't figure out how to use the WinNT WMI namespace with ManagementObject. When I try the following code it throws an "Invalid Parameter" exception.

public static void ResetPassword(string computerName, string username, string newPassword){ 
            ManagementObject managementObject = new ManagementObject("WinNT://" + computerName + "/" + username); // Throws Exception
            object[] newpasswordObj = {newPassword};
            managementObject.InvokeMethod("SetPassword", newpasswordObj);
}

Is there a better way to do this? (I'm using .NET 3.5)

Edit: Thanks Ely for pointing me in the right direction. Here is the code I ended up using:

public static void ResetPassword(string computerName, string username, string newPassword) { 
        DirectoryEntry directoryEntry = new DirectoryEntry(string.Format("WinNT://{0}/{1}", computerName, username)); 
        directoryEntry.Invoke("SetPassword", newPassword);
}

解决方案

Try the DirectoryEntry class instead of ManagementObject class.
