Question

I’m using WCF to create some REST service.
One of the Rest Service method need to get byte array as parameter ( picture as byte array ) and return some object.
I run this service using IIS.
But this is not working.

The code that i wrote :

[ServiceContract]
public interface IPicService
{
    [OperationContract, WebInvoke(Method="POST", UriTemplate = "GetPicReport/{imageName}")]
    Report GetPicReport( string imageName, Stream image );

}

[ServiceBehavior( AddressFilterMode = AddressFilterMode.Any )]
public class PicService: IPicService
{
    public Report GetPicReport( string imageName, Stream image )
    {
        return new Report ();
    }
}

I checking this code using explorer – but i get an error about missing parameter ( the image stream )

How can i test it ?
I can’t use the WCF Test Client – so i wrote simple application that create http call – and this method return error 404 ( server not found )

Can you try the below code:

var request = WebRequest.Create(string.Concat(serviceUrl, resourceUrl)) as HttpWebRequest;

        if (request != null)
        {
            request.ContentType = "text/xml";
            request.Method = method;
        }

        //var objContent = HttpContentExtensions.CreateDataContract(requestBody);
        if(method == "POST" && requestBody != null)
        {
            //byte[] requestBodyBytes = ToByteArrayUsingXmlSer(requestBody, "http://schemas.datacontract.org/2004/07/XMLService");
            byte[] requestBodyBytes = ToByteArrayUsingDataContractSer(requestBody);
            request.ContentLength = requestBodyBytes.Length;
            using (Stream postStream = request.GetRequestStream())
                postStream.Write(requestBodyBytes, 0, requestBodyBytes.Length);
            //request.Timeout = 60000;
        }

        if (request != null)
        {
            var response = request.GetResponse() as HttpWebResponse;
            if(response.StatusCode == HttpStatusCode.OK)
            {
                Stream responseStream = response.GetResponseStream();
                if (responseStream != null)
                {
                    var reader = new StreamReader(responseStream);

                    responseMessage = reader.ReadToEnd();
                }
            }
            else
            {
                responseMessage = response.StatusDescription;
            }
        }
