C＃中的Dynamics CRM SDK使用无效密码连接

我正在开发一个C＃应用程序，用于从Dynamics CRM Online检索数据。 要validationDynamics CRM的用户名和密码，我使用的是WhoAmIRequest。 它工作正常，直到出现以下情况。

1）使用有效URL，用户名和密码连接Dynamics CRM。

2）处置组织服务对象。

3）使用有效URL，用户名和无效密码重新连接Dynamics CRM。

在这种情况下，WhoAmIRequest也成功执行了。 但它应该失败。

以下是我正在使用的代码：

private void button6_Click(object sender, EventArgs e) { CrmConnection connection; string url = "Url=https://mytest.crm.dynamics.com ;Username=mytest@mytest.onmicrosoft.com; Password=goodpassword;"; connection = CrmConnection.Parse(url); OrganizationService orgService = new OrganizationService(connection); Guid userid = ((WhoAmIResponse)orgService.Execute(new WhoAmIRequest())).UserId; if (userid == null) MessageBox.Show("Login Failed"); else MessageBox.Show("Login Success"); orgService.Dispose(); url = "Url=https://mytest.crm.dynamics.com ;Username=mytest@mytest.onmicrosoft.com; Password=badpassword;"; connection = CrmConnection.Parse(url); orgService = new OrganizationService(connection); userid = ((WhoAmIResponse)orgService.Execute(new WhoAmIRequest())).UserId; if (userid == null) MessageBox.Show("Login Failed"); else MessageBox.Show("Login Success"); orgService.Dispose(); url = "Url=https://mytest.crm.dynamics.com ;Username=mytest@mytest.onmicrosoft.com; Password=goodpassowrd;"; connection = CrmConnection.Parse(url); orgService = new OrganizationService(connection); userid = ((WhoAmIResponse)orgService.Execute(new WhoAmIRequest())).UserId; if (userid == null) MessageBox.Show("Login Failed"); else MessageBox.Show("Login Success"); orgService.Dispose(); } 

上面代码的输出显示3个消息框为

登录成功

登录成功

登录成功

但它应该显示为

登录成功

登录失败

登录成功

我也尝试过Nicknow在需要validationCRM凭证问题时提出的答案，但没有任何帮助

任何帮助将受到高度赞赏。

谢谢并问候Venkatesan

 connection = CrmConnection.Parse(url); 

 connection = new CrmConnection(); connection.ServiceUri = new Uri("https://mytest.crm.dynamics.com"); var clientCredentials = new ClientCredentials(); clientCredentials.UserName.UserName = "mytest@mytest.onmicrosoft.com"; clientCredentials.UserName.Password = "goodpassword"; connection.ClientCredentials = clientCredentials;
