Question

我想以编程方式在我的客户端中将MaxReceivedMessageSize属性设置为某个更高的限制（由于（400）错误请求错误）。这是我正在使用的代码...

WCFServiceTestClient wcfClient = 
    new WCFServiceTestClient(new wsHttpBinding(), strServiceURL);

我的服务网址是动态的，因此无法使用web.config。

//The following code doesn't seem to take effect
((WSHttpBinding)wcfClient.ChannelFactory.Endpoint.Binding)
        .MaxReceivedMessageSize = 2147483647;

我做错了什么？

Answer 1

您是否尝试重新排序调用，以便在实例化客户端之前设置MaxReceivedMessageSize？例如，

var binding = new wsHttpBinding();
binding.MaxReceivedMessageSize = Int32.MaxValue; 
var wcfClient = new WCFServiceTestClient(binding, strServiceURL);

但这可能会或可能不会帮助您解决400错误。

我的wcf服务中遇到了类似的问题，我用以下方法解决了这个问题：

CustomBinding binding = (CustomBinding)PDAServiceContractClient.CreateDefaultBinding();
            HttpTransportBindingElement httpBindingElement = new HttpTransportBindingElement();
            httpBindingElement.MaxBufferSize = Int32.MaxValue;
            httpBindingElement.MaxReceivedMessageSize = Int32.MaxValue;
            binding.Elements.Add(httpBindingElement);

            string address = PDAServiceContractClient.EndpointAddress.Uri.ToString();
            m_proxy = new PDAServiceContractClient(binding, new EndpointAddress(address));

这很好用，虽然不是那么明显。它保留了所有现有的绑定属性，仅调整MaxReceivedMessageSize（顺便提一下，MaxBufferSize也增加到相同的大小。）

Dim oClient as WcfClient = New WcfClient
CType(oClient.Endpoint.Binding, ServiceModel.BasicHttpBinding).MaxReceivedMessageSize = Int32.MaxValue

如何在使用WCF客户端时以编程方式设置MaxReceivedMessageSize？
