I'm new to web services and i've been trying to create a custom one using this tutorial:


I've named my service as Files and created a new method on the webservice called UploadDocument:

    public string UploadDocument(string fileName, byte[] fileContents, string pathFolder)
        if (fileContents == null)
            return "Null Attachment";

            int iStartIndex = pathFolder.LastIndexOf("/");
            string sitePath = pathFolder.Remove(iStartIndex);
            string folderName = pathFolder.Substring(iStartIndex + 1);

            SPSite site = new SPSite(sitePath);
            SPWeb web = site.OpenWeb();

            SPFolder folder = web.GetFolder(folderName);

            string fileURL = fileName;

            folder.Files.Add(fileURL, fileContents);

            if (folder.Files[fileURL].CheckedOutByUser.Name != "")
                folder.Files[fileURL].CheckIn("File Checked In");

            return "File added successfully!";

        catch (System.Exception ex)
            return "Error: " + ex.Source + " - " + ex.Message;

I've done exactly as it's listed there, all the same name, methods etc.. and when i get to the point where you're asked to create the application that's going to consume the web service, the tutorial gives the following lines:

ServiceFolder.Files myUploadService = new ServiceFolder.Files();
myUploadService .UseDefaultCredentials = true;

but on my application, i can't call the web service as it's telling me to do, when i type


it won't have the option to call the classes i've created. it only gives me some options that are not the ones listed on the tutorial:

ServiceFolder.FilesSoap (Interface)
ServiceFolder.FilesSoapChannel (Interface)
ServiceFolder.FilesSoapClient (Class)
ServiceFolder.UploadDocumentCompletedEventArgs (Class)
ServiceFolder.UploadDocumentRequest (Class)
ServiceFolder.UploadDocumentRequestBody (Class)
ServiceFolder.UploadDocumentResponse (Class)
ServiceFolder.UploadDocumentResponseBody (Class)

Am i missing something? doing something wrong? i've tried to recreate the service a couple times and always get the same thing.

Thanks in advance.

That walkthrough has some, er, issues...

I wrote a blog post with an alternate version that you may find a little easier to follow.

Walkthrough: Creating a Custom ASP.NET (ASMX) Web Service in SharePoint 2010

  • Rob.. i don't have words to express how grateful i am for this walkthrough. Just one little question. How do you invoke the GetSiteListCount() method in your site/application? I've added the service reference, but i can't find how to call that method and use it's result on my code. Thanks a lot Nov 7, 2011 at 13:39
  • I've updated the blog post to demonstrate how to create a client for the service. Nov 7, 2011 at 14:42
  • Rob. It worked like a charm. Thank so you much for your help. Nov 7, 2011 at 16:24
