C# 在C中登录时发生异常#

我正在我的应用程序中使用windows应用程序和WCF服务。我已经在web服务器中发布了我的服务，并且在配置设置中引用了该endPointAddress。该应用程序在我的系统和某些系统中正常工作，但无法在其他系统中登录。它在登录时抛出一个异常

在这里我提到了我的例外，有谁能告诉我这个问题的解决方法吗？ 提前谢谢

例外情况：

与'http://example.com/DashBoardPointsService/Service.svc“针对目标”http://example.com/DashBoardPointsService/Service.svc"失败了。有关详细信息，请参阅内部异常

这是我的WCF服务配置设置：

    try

        EndpointAddress ep = new EndpointAddress(strNewURL);                

        WSHttpBinding binding = new WSHttpBinding();
        binding.Security.Mode = SecurityMode.Message;

        binding.SendTimeout = TimeSpan.MaxValue;

        binding.MaxReceivedMessageSize = 99999999;

        binding.ReaderQuotas.MaxArrayLength = 714748;

        binding.ReaderQuotas.MaxNameTableCharCount = 214749;
        binding.ReaderQuotas.MaxStringContentLength = 214749;

        objConnectionManager = new ChannelFactory<IService>(binding, ep);                
        objActivatedConnectionManager = objConnectionManager.CreateChannel();                

    }
    catch (Exception ex)
    {
        objlog.Write(ex);
    }
}

捕获（例外情况除外）

}
}

这可能是一个权利问题

客户端具有被服务器阻止的安全上下文

检查客户端的身份和服务器上的权限。

您可以发布WCF服务的配置吗？什么是clientCredential类型？客户端未能连接到的计算机是否在其他域中？这是我的wcf配置，我在函数中使用了它。我没有看到它。你错过格式化了吗？如果您试图使用wsHttpBinding，并且WCF服务或客户端位于不同的域上，那么它将无法工作。请改用basicHttpBinding
