我上面指定的代码从计算机中删除了一个登录，但没有像Damien_The_Unbeliever所述的那样处理用户配置文件。
我一直在挖掘我的PowerShell相当于我正在制作的应用程序，并发现我是如何做到这一点的。我使用删除用户配置文件。
以下是我的工作代码，任何可以使用它的灵魂：

public string RemoveUser(string machineId, string userName)
{
    string result = null;

    try
    {
        // Create scope and set to computer root.
        ManagementScope scope = new ManagementScope(@"\\" + machineId + @"\root\cimv2");

        // Connect.
        scope.Connect();

        // Create the query for user profiles and a searcher.
        SelectQuery query = new SelectQuery("Win32_UserProfile");
        ManagementObjectSearcher searcher = new ManagementObjectSearcher(scope, query);

        // Go through each WMI Instance
        foreach (ManagementObject mo in searcher.Get())
        {
            // Normalize username
            string normalUser = mo["LocalPath"].ToString().Split('\\').Last(); 

            // Check whether this is the user to be deleted
            if (normalUser == userName)
            {
                mo.Delete();
                result = "Found user: " + userName + ". Deleting...";
            }

        }

        // This code deletes a user login
        //DirectoryEntry locaDirectoryEntry = new DirectoryEntry("WinNT://" + machineId);
        //DirectoryEntry user = locaDirectoryEntry.Children.Find(userName);
        //locaDirectoryEntry.Children.Remove(user);
        //locaDirectoryEntry.CommitChanges();
    }
    catch (Exception e)
    {
        throw new Exception(e.Message);
    }

    return result;
}
