我可以'；t向WCF服务发送超过13 Mb的请求(超过了最大请求长度)

我不能向WCF服务发送超过13 Mb的数据。我得到超过最大请求长度异常

这是CreateServiceHost实现

    protected override ServiceHost CreateServiceHost(Type serviceType, Uri[] baseAddresses)
{
 IssuedSecurityTokenParameters itp = new IssuedSecurityTokenParameters(
                   "http://docs.oasis-open.org/wss/oasis-wss-saml-token-profile-1.1#SAMLV1.1");
            itp.IssuerAddress = new EndpointAddress(ConfigManager.ActAsSTS);
            itp.IssuerMetadataAddress = new EndpointAddress(ConfigManager.ActAsSTS + "/mex");
            // Create the security binding element
            SecurityBindingElement sbe = SecurityBindingElement.CreateIssuedTokenForCertificateBindingElement(itp);
            sbe.MessageSecurityVersion =
                MessageSecurityVersion.WSSecurity11WSTrust13WSSecureConversation13WSSecurityPolicy12BasicSecurityProfile10;

            // Create the HTTP transport binding element
            HttpTransportBindingElement httpBe = new HttpTransportBindingElement();
           httpBe.MaxReceivedMessageSize = httpBe.MaxBufferPoolSize = Constants.MaxFileSize;

           TextMessageEncodingBindingElement encodingElement = new TextMessageEncodingBindingElement();
            XmlDictionaryReaderQuotas quotas = encodingElement.ReaderQuotas;
            quotas.MaxArrayLength = quotas.MaxBytesPerRead = quotas.MaxStringContentLength = quotas.MaxNameTableCharCount = quotas.MaxDepth = (int)Constants.MaxFileSize;
            // Create the custom binding using the prepared binding elements
            CustomBinding binding = new CustomBinding(sbe, encodingElement, httpBe);

            EndpointAddress endpointAddress = new EndpointAddress(new Uri(ConfigManager.BaseAddress));
            ServiceEndpoint endpoint = new ServiceEndpoint(contractDescription, binding, endpointAddress);
            host.Description.Endpoints.Add(endpoint);

            host.Credentials.ServiceCertificate.SetCertificate(StoreLocation.LocalMachine, StoreName.My,
                X509FindType.FindByThumbprint, ConfigManager.ServiceCertificateThumbprint);
}

常数.MaxFileSize=20971520（20 Mb=20*1024*1024）

所有必要的设置MaxReceivedMessageSize，MaxBytesPerRead被设置。

web.config文件

我可以'；t向WCF服务发送超过13 Mb的请求(超过了最大请求长度)

中也有<httpRuntime maxRequestLength="20480"/>设置

如果我正确理解您想要实现的目标——您想要创建接收大文件上传的WCF服务。

如果是这样的话，也许将WCF与流绑定一起使用将帮助您实现目标。

不久前，我写了一个服务，使用类似的配置接受大文件上传：

<netTcpBinding>
 <binding name="netTcpStreaming" sendTimeout="00:15:00" transferMode="Streamed" maxReceivedMessageSize="2147483648">
          <security mode="None" />
  </binding>
</netTcpBinding>
