Error: Could not find default endpoint element that references contract

问题

I am writing a below code to create a MM component in tridion through core service, but i am getting error to run this service,

 public ComponentData GetNewMultimediaComponent(CoreServiceClient Client, string folderUri, string schemaUri, string title, FileInfo fi)
    {
        if (fi.Extension == ".png")
        {
            string mmType = GetMultiMediaType(fi.Extension);
            if (mmType != null)
            {
                string tempLocation = "";

                UploadResponse us = new UploadResponse();
                using (StreamUploadClient streamClient = GetConnection())
                {
                    FileStream objfilestream = new FileStream(fi.FullName, FileMode.Open, FileAccess.Read);
                    tempLocation = streamClient.UploadBinaryContent(fi.Name.ToLower(), objfilestream);
                }

                BinaryContentData bcd = new BinaryContentData
                {
                    UploadFromFile = fi.FullName,
                    MultimediaType = new LinkToMultimediaTypeData { IdRef = mmType },
                    Filename = fi.Name,
                    IsExternal = false
                };

                ComponentData res = GetNewComponent(folderUri, schemaUri, title);
                res.ComponentType = ComponentType.Multimedia;
                res.BinaryContent = bcd;

                res = (ComponentData)Client.Create(res, new ReadOptions());

In the above code i am getting the error on below line

using (StreamUploadClient streamClient = new StreamUploadClient())

Just for update, I am using tridion core services by DLL without config file and create connection successfully.

Connection setting

public StreamUploadClient GetConnection()
    {
        BasicHttpBinding basicHttpBinding = new BasicHttpBinding
        {
            MaxReceivedMessageSize = 10485760,
            ReaderQuotas = new XmlDictionaryReaderQuotas
            {
                MaxStringContentLength = 10485760,
                MaxArrayLength = 10485760
            },
            Security = new BasicHttpSecurity
            {
                Mode = BasicHttpSecurityMode.None,
            }
        };

        EndpointAddress remoteAddress = new EndpointAddress("http://abc/webservices/CoreService2011.svc/streamUpload_basicHttp");

        StreamUploadClient client = new StreamUploadClient(basicHttpBinding, remoteAddress);
        try
        {
            client.Open();
        }
        catch (Exception ex)
        {
           //log.Error("Error:CoreServiceConectionOpen:Common:" + ex.Message);
            throw ex;
        }

        return client;
    }

Now, getting error on below line

tempLocation = streamClient.UploadBinaryContent(fi.Name.ToLower(), objfilestream);

{System.ServiceModel.ProtocolException: The content type multipart/related; type="application/xop+xml";start="<http://tempuri.org/0>";boundary="uuid:739a821f-aee2-4eaf-9206-05a1ed19311c+id=1";start-info="text/xml" of the response message does not match the content type of the binding (text/xml; charset=utf-8).

'.

Can any one help me to resolve this issue?

The problem is in this line:

StreamUploadClient streamClient = new StreamUploadClient()

This is a separate endpoint you are trying to connect to. Typically it would pick adress and all other properties of a connection from app.config, but as you don't have any you need to provide all the required parameters yourself, similar to what you do with your CoreService. Refer to app.config sample to see what paremeters you need.

Something like this:

    public StreamUploadClient GetConnection()
    {
        BasicHttpBinding basicHttpBinding = new BasicHttpBinding
        {
            MaxReceivedMessageSize = 10485760,
            ReaderQuotas = new XmlDictionaryReaderQuotas
            {
                MaxStringContentLength = 10485760,
                MaxArrayLength = 10485760
            },
            MessageEncoding = WSMessageEncoding.Mtom,
            Security = new BasicHttpSecurity
            {
                Mode = BasicHttpSecurityMode.None,
            }
        };

        EndpointAddress remoteAddress = new EndpointAddress("http://abc/webservices/CoreService2011.svc/streamUpload_basicHttp");

        StreamUploadClient client = new StreamUploadClient (basicHttpBinding, remoteAddress);
        try
        {
            client.Open();
        }
        catch (Exception ex)
        {
            log.Error("Error:CoreServiceConectionOpen:Common:" + ex.Message);
            throw ex;
        }

        return client;
    }
