C# 如何使用反射调用WCF服务？

我有WCF服务端点；我无权访问该服务的接口（即合同）。我需要调用它的端点详细信息和方法名

我怎样才能在C#中做到这一点；我正在使用NetCPBinding

提前谢谢

Ocean不确定这是否正是您想要的，但是您可以使用WsdlImporter联系WSDL并获取元数据（如DataContracts和OperationContracts）。例如：

        MetadataExchangeClientMode mexMode = MetadataExchangeClientMode.HttpGet;

        // Get Metadata file from service
        MetadataExchangeClient mexClient = new MetadataExchangeClient(mexAddress, mexMode);
        mexClient.ResolveMetadataReferences = true;
        MetadataSet metaSet = mexClient.GetMetadata(mexAddress, mexMode);

        //Import all contracts and endpoints
        WsdlImporter importer = new WsdlImporter(metaSet);
        var contracts = importer.ImportAllContracts();
        ServiceEndpointCollection allEndpoints = importer.ImportAllEndpoints();

        //Generate type information for each contract
        ServiceContractGenerator generator = new ServiceContractGenerator();
        this.EndpointsForContracts = new Dictionary<string, IEnumerable<ServiceEndpoint>>();

        foreach (ContractDescription contract in contracts)
        {
            generator.GenerateServiceContractType(contract);
            // Inspect if the name matches one you're looking for, or do whatever
            //  else you might need
        }

最后，您可以相应地执行这些方法：

Type clientProxyType = this.Cr.CompiledAssembly.GetTypes().First(t => t.IsClass && t.GetInterface(listServiceContracts.SelectedValue) != null && t.GetInterface(typeof(ICommunicationObject).Name) != null);
object dataContract = this.Cr.CompiledAssembly.CreateInstance(dataContractType.FullName, false, System.Reflection.BindingFlags.CreateInstance, null, null, CultureInfo.CurrentCulture, null);

// set the dataContract properties however they need to be set

// Get the first service endpoint for the contract
        ServiceEndpoint serviceEndPoint = this.EndpointsForContracts[listServiceContracts.SelectedValue].First();

        object clientProxyInstance = this.Cr.CompiledAssembly.CreateInstance(clientProxyType.Name, false, System.Reflection.BindingFlags.CreateInstance, null, new object[] { serviceEndPoint.Binding, serviceEndPoint.Address }, CultureInfo.CurrentCulture, null);

        Type myType = clientProxyInstance.GetType();
        object[] arg = { dataContract };

        // Now call the remote procedure via SOAP, get back response
        var returnVal = myType.InvokeMember("OPERATION YOU WANT TO EXECUTE", BindingFlags.InvokeMethod, null, clientProxyInstance, arg);

再说一次，这可能不适合你想要做的事情，而且你的帖子是很久以前的事了，所以这可能是老消息。但以防万一。。。希望这是有帮助的。您可能需要检查返回的类型，以确定如何正确设置DataContract参数。此外，上面假设您正在调用的方法只接受一个参数，即DataContract对象

如果您仍然需要它，希望这能让您走上正确的轨道。

您是在尝试连接到任意服务还是单个已知服务？如果您有程序集，您可以简单地引用程序集并实例化您正在谈论的类型，而无需进行反射。请解释为什么你不能这样做，以便有人能提供一些建议。这里有一个答案可能会有所帮助：我不会事先知道这项服务；我将无法访问程序集，因此无法实例化。是的，这将是任意的服务。而且我也没有合同。。。

Type clientProxyType = this.Cr.CompiledAssembly.GetTypes().First(t => t.IsClass && t.GetInterface(listServiceContracts.SelectedValue) != null && t.GetInterface(typeof(ICommunicationObject).Name) != null);
object dataContract = this.Cr.CompiledAssembly.CreateInstance(dataContractType.FullName, false, System.Reflection.BindingFlags.CreateInstance, null, null, CultureInfo.CurrentCulture, null);

// set the dataContract properties however they need to be set

// Get the first service endpoint for the contract
        ServiceEndpoint serviceEndPoint = this.EndpointsForContracts[listServiceContracts.SelectedValue].First();

        object clientProxyInstance = this.Cr.CompiledAssembly.CreateInstance(clientProxyType.Name, false, System.Reflection.BindingFlags.CreateInstance, null, new object[] { serviceEndPoint.Binding, serviceEndPoint.Address }, CultureInfo.CurrentCulture, null);

        Type myType = clientProxyInstance.GetType();
        object[] arg = { dataContract };

        // Now call the remote procedure via SOAP, get back response
        var returnVal = myType.InvokeMember("OPERATION YOU WANT TO EXECUTE", BindingFlags.InvokeMethod, null, clientProxyInstance, arg);
