异常(System.Reflection.targetInvocationException)通过WCF请求

Question

我有一个错误，当我通过其他Proyect中的反射从WindowsForm发送一个大字符串到WCF。我看到我需要在web.config中将一些参数放在服务器和app.config中。我做到了，但我有同样的例外。同样，当我生成实例时，我将任何C＃代码的行都放在客户端中。C＃

中的代码

   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);  

我正在尝试发送一个参数：字符串中的XML文档

 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);

我在上线中有错误。

Thanks in advance.

Answer 1

最后，我可以解决此问题，我在app.config中不需要任何内容，wef.config配置了相同的代码，并将此行放入客户端。

我只需要施放通道，然后施放basichtpbinding并设置参数。

谢谢大家。
