为什么Powershell不清算?

所以,在我第二次运行它之后,我的问题是让我的函数生成它自己的数据。我第一次生成GetUsers命令,如果我的用户名和密码是正确的,它将返回与我的用户的arraylist。如果我再次运行它,无论我使用什么用户名或密码,它都将返回相同的用户。我确定我的代码非常混乱,但我一直在搞乱它试图清除它。

至于一点背景,我认为自己是一个新手程序员,所以问题很可能是非常基本的。

谢谢!

 public ArrayList GetUsers(string user, string pass)
        {
            InitialSessionState iss = InitialSessionState.CreateDefault();

            iss.ImportPSModule(new[] { "MSOnline" });
            using (Runspace myRunSpace = RunspaceFactory.CreateRunspace(iss))
            {
              myRunSpace.Open();
              using (System.Management.Automation.PowerShell powershell = System.Management.Automation.PowerShell.Create())
              {
                  ArrayList available_users = new ArrayList();

                  //create Powershell runspace

                  powershell.Runspace = myRunSpace;

                  Command connect = new Command("Connect-MsolService");
                  System.Security.SecureString secureString = new System.Security.SecureString();
                  string myPassword = pass;
                  foreach (char c in myPassword)
                      secureString.AppendChar(c);

                  connect.Parameters.Add("Credential", new PSCredential(user, secureString));
                  powershell.Commands.AddCommand(connect);

                  Collection<PSObject> results = null;
                  results = powershell.Invoke();
                  powershell.Commands.Clear();

                  Command getuser = new Command("Get-MsolUser");
                  powershell.Commands.AddCommand(getuser);
                  results = null;

                  powershell.Stop();

                  results = powershell.Invoke();

                  foreach (PSObject item in results)
                  {
                      string userprincipalname = item.Properties["UserPrincipalName"].Value as string;
                      available_users.Add(userprincipalname);
                  }

                  powershell.Dispose();
                  myRunSpace.Dispose();

                  powershell.Runspace.Dispose();
                  powershell.Runspace.Close();
                  myRunSpace.Close();
                  return available_users;
              }
            }
        }

您是否尝试过显式删除或清空available_users类型?我不认为这是必要的,但是......
