通過WCF發送異常（System.Reflection.TargetInvocationException）請求

Question

當我通過其他項目中的反射從WindowsForm發送大量字符串到WCF時，出現錯誤。我看到我需要在web.config中的服務器和app.config客戶端（winform）中放置一些參數。我做到了，但我有同樣的例外。 另外，當我生成實例時，我在客戶端中放置了任何C＃代碼行。 在C＃中的代碼

CompilerParameters compilerParameters = new CompilerParameters(new string[] { "System.dll", "System.ServiceModel.dll", "System.Runtime.Serialization.dll" }); 
      compilerParameters.GenerateInMemory = true; 

      //Gets the compiled assembly. 
      compilerResults = codeDomProvider.CompileAssemblyFromDom(compilerParameters, serviceContractGenerator.TargetCompileUnit); 

    //implemented by all the communication oriented objects). 
       Type proxyType = compilerResults.CompiledAssembly.GetTypes().First(t => t.IsClass && t.GetInterface(contractName) != null); 


       // Now we get the first service endpoint for the particular contract. 
       ServiceEndpoint serviceEndpoint = endpointsForContracts[contractName].First(); 

       // Create an instance of the proxy by passing the endpoint binding and address as parameters. 
       proxyInstance = compilerResults.CompiledAssembly.CreateInstance(proxyType.Name, false, System.Reflection.BindingFlags.CreateInstance, null, 
        new object[] { serviceEndpoint.Binding, serviceEndpoint.Address }, System.Globalization.CultureInfo.CurrentCulture, null); 

       //Set timeOut in minutes 
       PropertyInfo channelFactoryProperty = proxyInstance.GetType().GetProperty("ChannelFactory"); 

       if (channelFactoryProperty == null) 
       { 
        throw new InvalidOperationException("There is no ''ChannelFactory'' property on the DomainClient."); 
       } 
       ChannelFactory factory = (ChannelFactory)channelFactoryProperty.GetValue(proxyInstance, null); 
       factory.Endpoint.Binding.SendTimeout = new TimeSpan(0, 10, 0); 
       factory.Endpoint.Binding.OpenTimeout = new TimeSpan(0, 10, 0); 
       factory.Endpoint.Binding.ReceiveTimeout = new TimeSpan(0, 10, 0); 
       factory.Endpoint.Binding.CloseTimeout = new TimeSpan(0, 10, 0); 


       PropertyInfo channelFactoryPropert = proxyInstance.GetType().GetProperty("InnerChannel"); 
       System.ServiceModel.IClientChannel factor = (System.ServiceModel.IClientChannel)channelFactoryPropert.GetValue(proxyInstance, null); 
       factor.OperationTimeout.Add(new TimeSpan(0, 10, 0)); 
       factor.OperationTimeout = new TimeSpan(0, 10, 0); 

我試圖發送一個參數：XML文檔中的字符串

var proxyInstance = GetProxyInstance(ref compilerResults, "http://localhost:49854/ServicioPrueba.svc?wsdl", "IContratoPrueba"); 
       string operationName = "GetData";//Nombre de metodo a llamar 

       XmlDocument doc = new XmlDocument(); 
       doc.Load(@"C:\\pru.xml"); 
       string xmlString = doc.InnerXml; 

       var methodInfo = proxyInstance.GetType().GetMethod(operationName); 
       //int var = int.Parse(textBox1.Text); 
       object[] operationParameters = new object[] { xmlString }; 

     var invoke= methodInfo.Invoke(proxyInstance, BindingFlags.InvokeMethod, null, operationParameters, null); 

我在上面一行的錯誤。

Thanks in advance. 

Answer 1

最後，我可以解決這個問題，我不需要app.config中的任何東西，wef.config配置了相同的代碼，並把這些行放在客戶端。

我只需要強制轉換ChannelFactory，然後強制轉換BasicHttpBinding並設置參數。

謝謝大家。

  var timeOut=new TimeSpan(0, 10, 0); 
      int timeOutInt = 2147483647; 
      PropertyInfo channelFactoryProperty = proxyInstance.GetType().GetProperty("ChannelFactory"); 
     if (channelFactoryProperty == null) 
     { 
      throw new InvalidOperationException("There is no ''ChannelFactory'' property on the DomainClient."); 
     } 
     ChannelFactory factory = (ChannelFactory)channelFactoryProperty.GetValue(proxyInstance, null); 
     factory.Endpoint.Binding.SendTimeout = timeOut; 
     factory.Endpoint.Binding.OpenTimeout = timeOut; 
     factory.Endpoint.Binding.ReceiveTimeout = timeOut; 
     factory.Endpoint.Binding.CloseTimeout = timeOut; 

     BasicHttpBinding _binding = (BasicHttpBinding)factory.Endpoint.Binding; 
     _binding.MaxBufferPoolSize = timeOutInt; 
     _binding.MaxBufferSize = timeOutInt; 
     _binding.MaxReceivedMessageSize = timeOutInt; 
     _binding.OpenTimeout = timeOut;
