Question

I used to code only in databases enviroments. Recent changes in the corp. made me start developing in whole new worlds.
This new project is something like SQL – C# – PHP.

The class I’ve been working on in VS2008 is almost dnoe. It calls all the SQL SPs I need and the info is there in the DataReaders.
When It came to read that info from PHP so I could populate the website I found out it wasn’t that easy. I was recommended into trying several options, the one that suits the best for the project is to create a Web Service and then consume it (please be patient, As I just stated I’m new to most web related programming)
So, I’m trying to WCF/Rest and then consume it from PHP but I haven’t got there yet.

I’ve read and watched several tutorials on WCF and It seems to be smooth, but all I’ve read is:

. Create Interface with its OperationContracts.

. Create Service with DataMembers etc and define the Methods listed in the Interface.

Ok, but what I’d like to do is not to specify any methods there, since all I want is to call C# method I’ve already written.
Should I do that in the Service or in the Interface? And first of all, is this the right the way to approach it?

Answer 1

You would want to write service methods that implement an operation contract interface. The service methods can call the C# code that you’ve already written.

For example, here is a simple service interface:

[ServiceContract]
public interface IYourService
{
    [OperationContract]
    int GetCountOfTransactions(string filter);
}

And then you would implement this interface in your service class:

public class YourService : IYourService
{
    public int GetCountOfTransactions(string filter)
    {
        // Call your existing code
        YourClass yourClass = new YourClass();
        return yourClass.GetCountOfTransactions(filter);
    }
}

There are plenty of examples out there for setting this up as a REST service, but I think you’re on the right track.

The trickiest part is usually setting up the binding configuration to make sure all of your consuming client applications can connect.

Hopefully this helps.
