我無法發送超過13 Mb的WCF服務。我得到超過最大請求長度例外我無法發送超過13 Mb的WCF服務(超過最大請求長度)

這裏是CreateServiceHost實施

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); 
} 

Constants.MaxFileSize = 20971520(20 MB = 20 * 1024 * 1024)

所有必要的設置MaxReceivedMessageSize ,MaxBytesPerRead ...已設置。

也有是在web.config文件<httpRuntime maxRequestLength="20480"/>設置

這僅僅是一個在黑暗中拍攝,因爲我還沒有與WCF的工作很多,這是一個,而以前,但是由於您使用的是HTTP作爲傳輸方式,因此消息可能是base64編碼的,因此13 MB的實際數據被編碼爲20 MB的電纜? [文檔](http://msdn.microsoft.com/library/e1f13641.aspx)沒有提到任何類似的東西,我認爲base64通常會導致大小增加30%,所以也許不是這樣。 – BACON 2012-03-14 13:59:07

如果我理解正確的話,你想達到什麼 - 你想創建一個接收的大文件上傳WCF服務。

如果是這樣,也許使用WCF with streaming綁定將幫助您實現目標。

前一段時間我寫了接受使用類似配置大文件上傳到該服務:

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