C# 修改本地管理员密码

发布于 2024-07-08 21:37:14 字数 1210 浏览 5 评论 0原文

我正在寻找一种方法来更改 Windows（本例中为 XP）计算机上的本地用户帐户（本地管理员）的密码。我已阅读 CodeProject 文章关于实现此目的的一种方法，但这看起来并不“干净”。

我可以看到这可能与WMI有关，所以这可能是答案，但我不知道如何将 WinNT WMI 命名空间与 ManagementObject 一起使用。当我尝试以下代码时，它会抛出“无效参数”异常。

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);
}

有一个更好的方法吗？（我正在使用 .NET 3.5）

编辑：感谢 Ely 为我指明了正确的方向。这是我最终使用的代码：

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);
}

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);
}

尝试使用 DirectoryEntry 类而不是 ManagementObject 类。

正如 Ely 指出的，您可以根据 MSDN 使用 System.DirectoryServices 代码来完成此操作：

String myADSPath = "LDAP://onecity/CN=Users,
     DC=onecity,DC=corp,DC=fabrikam,DC=com";

// Create an Instance of DirectoryEntry.
DirectoryEntry myDirectoryEntry = new DirectoryEntry(myADSPath);
myDirectoryEntry.Username = UserName;
myDirectoryEntry.Password = SecurelyStoredPassword;

As Ely noted, you can use the System.DirectoryServices code to accomplish this per MSDN:

String myADSPath = "LDAP://onecity/CN=Users,
     DC=onecity,DC=corp,DC=fabrikam,DC=com";

// Create an Instance of DirectoryEntry.
DirectoryEntry myDirectoryEntry = new DirectoryEntry(myADSPath);
myDirectoryEntry.Username = UserName;
myDirectoryEntry.Password = SecurelyStoredPassword;
