如何以编程方式设置 WCF 客户端 maxBufferSize 参数？

Question

我以编程方式设置 wcf 客户端参数，如下所示：

try
{
ServiceReference1.MyDbServiceClient webService =
    new ServiceReference1.MyDbServiceClient(new System.ServiceModel.BasicHttpBinding(),
    new System.ServiceModel.EndpointAddress((string)((App)Application.Current).Resources["wcfMyDBServiceEndPoint"]));

    webService.GetSeriesImagesCompleted += new EventHandler<ServiceReference1.GetSeriesImagesCompletedEventArgs>(webService_GetSeriesImagesCompleted);
    webService.GetSeriesImagesAsync(index);
}

对于默认的 maxBufferSize，它工作得很好。但是，当客户端超过默认大小时，会出现异常：“已超出传入消息的最大消息大小配额 (65536)”。

如何在代码中设置这个参数？ 谢谢。

BasicHttpBinding binding = new BasicHttpBinding(BasicHttpSecurityMode.None);
binding.CloseTimeout = new TimeSpan(00, 05, 00);
binding.OpenTimeout = new TimeSpan(00, 05, 00);
binding.ReceiveTimeout = new TimeSpan(00, 05, 00);
binding.SendTimeout = new TimeSpan(00, 05, 00);
binding.TextEncoding = System.Text.Encoding.UTF8;
binding.MaxReceivedMessageSize = int.MaxValue;
binding.MaxBufferSize = int.MaxValue;             

binding.GetType().GetProperty("ReaderQuotas").SetValue(binding, XmlDictionaryReaderQuotas.Max, null);

根据您的要求创建绑定。
