Adding/Calling WCF Reference

Question

User-2017823710 posted

Hi,

WCF Service:  TestService\TestService.svc

WCF Method: Public String GetDetails(String Input)

Calling Service: I am adding the TestService.svc and I create a proxy object of ITestService. However I am not able to call GetDetails() using the proxy object and pass the string parameter. Instead Iam forced to create a ITestServiceInput object and pass the "Input" and also the output is not coming as string but as ITestServiceOutput.

Why am I not able to just pass a normal string and get a string returned as output? Please let me know if I am doing something wrong.

Thanks!!

Sid

Hi,

Are you using data contract ?

Please don't use it  make it normal. I hope it will resolve your  problem.

Did you follow the steps as shown here : http://www.codeproject.com/Articles/42643/Creating-and-Consuming-Your-First-WCF-Service

When passing/getting native .NET objects you do not need any datacontracts. Only mark the service methods as "OperationContract" and the service as ServiceContract. That should do the trick.

Hi,

According to your description, I have created the following example, please try to refer to:

ITestService.cs:

[ServiceContract]
    public interface ITestService
    {
        [OperationContract]
        String GetDetails(String Input);
    }

TestService.svc.cs:

public class TestService : ITestService
    {
        public String GetDetails(String Input)
        {
            return Input;
        }
    }

After running it in the browser, then we can call this TestService in the client as below:

  class Program
    {
        static void Main(string[] args)
        {
            ServiceReference1.TestServiceClient client = new ServiceReference1.TestServiceClient();
            string str = client.GetDetails("Good Work");
            Console.WriteLine(str);
            Console.ReadLine();
        }
    }

If you have any other problem, please let me know in your free time.
