没有重载方法需要2个参数

Question

Hi I have a WCF service and within it I have this method

void SendData(int pumpNo, List<String> pumpInfo);

however when I try to pass an int and a list into it, I get an error saying

Error 1 No overload for method 'SendData' takes 2 arguments

This is how I passed data to it in the WCF client

sendpumpdata.SendData(pumpID, pumpData);

ok so at the top I create an instance of the WCF service by doing...

ServiceReference1.iCommClient sendpumpdata = new Pumps.ServiceReference1.iCommClient();

also in my service.cs I have created the method defined in the IService.cs

A WCF web service leverages client generated code (ie a proxy) to communicate with the server. In your situation, even though the server code has two parameters, your client generated code must be out of date.

If you're using a Web Reference or a Service Reference just right click and Update Reference. If you're using a static WSDL then navigate to the WSDL hosted locally for the WCF service and save it to disk and then overwrite the one in your project.
