Question

I am working on an API kind of project,

I have wrote a WebMethod (not exactly. I am using MVC to create REST like API)

public UploadFileImage(string employeeId, byte[] imageBytes, string imageName)
{
    // saves the imagebyte as an image to a folder
}

the web service would be consumed by a web app, or windows or even iphone or such portable stuffs. I am testing my web service using a web app, by simple httpPost.

string Post(Uri RequestUri, string Data)
    {
        try
        {
            HttpWebRequest request = HttpWebRequest.Create(RequestUri) as HttpWebRequest;

            request.Method = "POST";

            request.ContentType = IsXml.Checked ? "text/xml" : "application/x-www-form-urlencoded";

            byte[] bytes = Encoding.ASCII.GetBytes(Data);
            Stream os = null; // send the Post
            request.ContentLength = bytes.Length;   //Count bytes to send
            os = request.GetRequestStream();
            os.Write(bytes, 0, bytes.Length);

            HttpWebResponse httpWebResponse = (HttpWebResponse)request.GetResponse();
            StreamReader streamReader = new StreamReader(request.GetResponse().GetResponseStream());
            return streamReader.ReadToEnd();

        }
        catch (Exception ex)
        {
            return ex.Message;
        }
    }

This code works fine for evey method like, AddEmployee, DeleteEmployee etc. THe parameter Data is of form “Id=123&name=abcdefgh&desig=Developer”,

How I call any other function is
Post(new Uri(“http://localhost/addemployee”),”name=abcd&password=efgh”)
where post is the function i wrote.

All good for all functions. Except that I dont know how to consume the above mentioned function UploadFileImage to upload an image?

Thanks

Answer 1

Try encoding the imageBytes as Base64.
