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＃中的代碼通過WCF發送異常（System.Reflection.TargetInvocationException）請求
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。

你的問題沒有錯誤。捕獲異常詳細信息並將其添加到[編輯]。 – Will
我把它。我有一個svclog文件來保存日誌，由服務器和客戶端 – Javysk
這有幫助。您是否在WPF標籤中搜索了「請求實體太大」的問題？有很多，例如http://stackoverflow.com/questions/10122957/iis7-413-request-entity-too-large-uploadreadaheadsize它可能與您的有效載荷（請求）的大小有關太大了。您可以通過配置對此進行調整。祝你好運！ – Will
