在代码中创建NetTcpBinding时,如何设置ReliableSession.MaxPendingChannels？

Question

我们收到此错误:

System.ServiceModel.ServerTooBusyException:RM Destination拒绝了创建可靠会话的请求.服务器'net.tcp:// localhost:50000 /'太忙,无法处理此请求.稍后再试.该频道无法打开.

据我了解,我需要在ReliableSession绑定中增加MaxPendingChannels的值.

但是我们在这样的代码中配置WCF:

serviceHost = new ServiceHost(typeof(MyServiceClass));
ServiceEndpoint endPoint = serviceHost.AddServiceEndpoint(
    typeof(IMyService),
    new NetTcpBinding(SecurityMode.None, true),
    endPointAddress);

那么如何以编程方式设置ReliableSession.MaxPendingChannels？(我可以找到的所有示例都使用配置文件)

在此网页上搜索MaxPendingChannels 有一个选项,但它似乎过于复杂.

这就是我做的:

 private Binding CreateBindingWith_MaxPendingChannels_Set(Binding baseBinding)
 {
     BindingElementCollection elements = baseBinding.CreateBindingElements();
     ReliableSessionBindingElement reliableSessionElement = 
                elements.Find<ReliableSessionBindingElement>();
     if (reliableSessionElement != null)
     {
         reliableSessionElement.MaxPendingChannels = 128;

         CustomBinding newBinding = new CustomBinding(elements);

         newBinding.CloseTimeout = baseBinding.CloseTimeout;
         newBinding.OpenTimeout = baseBinding.OpenTimeout;
         newBinding.ReceiveTimeout = baseBinding.ReceiveTimeout;
         newBinding.SendTimeout = baseBinding.SendTimeout;
         newBinding.Name = baseBinding.Name;
         newBinding.Namespace = baseBinding.Namespace;
         return newBinding;
     }
     else
     {
         throw new Exception("the base binding does not " +
                             "have ReliableSessionBindingElement");
     }
 }

.....

 Binding customBinding = CreateBindingWith_MaxPendingChannels_Set(
      new NetTcpBinding(SecurityMode.None, true));

 serviceHost = new ServiceHost(typeof(MyService));
 ServiceEndpoint endPoint = serviceHost.AddServiceEndpoint(
                    typeof(IMyService),
                    customBinding,
                    endPointAddress);
