Question

我收到“目标名称不正确或服务器拒绝了客户端凭据。”将配置从localhost更改为QA服务器时出现错误消息。

以下是代码失败的地方：

          ServiceReference1.MaestroServiceClient client; 

        try

        {
            client = new ServiceReference1.MaestroServiceClient("NamedPipes");

            client.ClientCredentials.UserName.UserName = "xxx";
            client.ClientCredentials.UserName.Password = "xxx";

            // fails on this line
            lbRateCards.ItemsSource = ((System.Data.DataTable)client.GetRateCardsDataTable(networkId)).DefaultView;
            lbRateCards.DisplayMemberPath = "RATECODE";
            lbRateCards.SelectedValuePath = "RATECARDID";
        }
        catch (Exception ex) 
        {
            lbRateCard.Content = ex.Message + ": " + ex.StackTrace.ToString();
        }

我添加了用户名和密码，看看是否会影响结果。正如您所看到的，它连接到服务但在执行方法时失败。

感谢任何帮助。我整个星期都在敲打我的头。

下面是我的app.config。我将从WPF浏览器应用程序转到wfc服务。

除非您的WPF应用程序也在QA服务器上运行，否则您无法将配置从localhost更改为QA服务器（在这种情况下，您仍然可以使用localhost）。 WCF中命名管道的限制是它只能用于同一台机器上的进程间通信。因此，如果您的客户端和服务在不同的计算机上运行，则无法使用基于命名管道的绑定进行通信。

WCF“目标名称不正确或服务器已拒绝客户端凭据。”
