SlideShare .NET API Wrapper

October 18, 2009, 15:29

In a recent project I had to work with the SlideShare API. Thankfully there was some good documentation to get me started, and even a .NET wrapper for the first version of the API.

From SlideShare

SlideShare is a business media site for sharing presentations, documents and pdfs.

After downloading and playing around with the code I decided to upgrade it to version 2 of the API. I encourage you to take a look at the documentation if you haven’t, to see what’s new in version 2 of the API, and what’s available.

SlideShare API Wrapper Methods

Here are the methods that I’ve exposed and made available for you to use. Big thanks to Brian Grinstead for his blog post Multipart Form Post in C# and for Gaurav Gupta for creating the wrapper class for the first version, which this code is based on.

GetSlideshow
GetSlideshowsForTag
GetSlideshowsForGroup
GetSlideshowsForUser
SlideshowSearch
GetUserGroups
GetUserContacts
GetUserTags
EditSlideshow
DeleteSlideshow
UploadSlideshow

To use it simply download the code (see link at the bottom of this post), copy the SlideShareAPI.dll into your bin folder and make a reference to it in your project. After you’ve done that you’ll be able to create an instance of the SlideShare class which will expose the methods above.

Remember that you also need an API Key and Shared Secret. Go to the Apply for API Keys page and fill out the form. You should then receive an email with both keys.

Example

Lets get some slideshows that are tagged with web, bind them to a Repeater control and display them to the user.

using System;
using System.Linq;
using System.Xml.Linq;
using SlideShareAPI;
 
namespace FV.Templates.FV.Pages
{
    public partial class SlideShareTest : System.Web.UI.Page
    {
        protected override void OnLoad(EventArgs e)
        {
            base.OnLoad(e);
 
            var slideShare = new SlideShare("API Key", "Shared secret");
 
            var xml = XElement.Parse(slideShare.GetSlideshowsForTag("web", 0, 10));
 
            var slideshows = from slideshare in xml.Elements("Slideshow")
                            select new
                            {
                                Title = slideshare.Element("Title").Value,
                                Description = slideshare.Element("Description").Value,
                                EmbedCode = slideshare.Element("Embed").Value
                            };
 
            rptSlideshows.DataSource = slideshows;
            rptSlideshows.DataBind();
        }
    }
}

I use Linq to XML and create anonymous objects that I then databind to my Repeater.

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="SlideShareTest.aspx.cs" Inherits="FV.Templates.FV.Pages.SlideShareTest" %>
 
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
 
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
    <asp:Repeater runat="server" ID="rptSlideshows">
    <HeaderTemplate><ul></HeaderTemplate>
    <ItemTemplate>
        <li>
        <h3><%# HttpUtility.HtmlEncode(Eval("Title").ToString()) %></h3>
        <p><%# HttpUtility.HtmlEncode(Eval("Description").ToString()) %></p>
        <%# HttpUtility.HtmlDecode(Eval("EmbedCode").ToString())%>
        </li>
    </ItemTemplate>
    <FooterTemplate></ul></FooterTemplate>
</asp:Repeater>
    </form>
</body>
</html>

Most of the code is commented and available through Visual Studio Intellisense. You can also go through and change the code to your needs.
