creating a webservice that accepts a file (Stream) doesnt want other params

Question

I have a File i want to upload to a Webservice, but it needs additional params, so I create some hidden fields with the associated name:value pairs to get pushed to the serv

Answer 1

How about using HttpRequest.QueryString[]?

[OperationContract]
[WebInvoke(Method = "POST", ResponseFormat = WebMessageFormat.Json, UriTemplate = "NewImage")]
string NewImage(Stream data);

you call it through the URL like:

\NewImage?server={server}&datasource={datasource}&document={doc}&image_id={id}

Then in your code:

public string NewImage(Stream imgStream)
{
    var request = System.Web.HttpContext.Current.Request;

    var server= request.QueryString["server"];
    var datasource = request.QueryString["datasource"];
    var document= request.QueryString["document"];
    var image_id= request.QueryString["image_id"];

    ...
}

I'd been looking for something like this for a while, and just stumbled across it today.
