ASP.NET Hosting :: How to Submit Blog Post in Wordpres Using ASP.NET

WordPress is a free and opensource blogging tool and content management system based on PHP and MySQL. It is used widely around the world and currently the most famous blogging system in use over the internet.

Since WordPress is written in PHP and our application is going to be an ASP .NET application and the two are entirely different technologies and architectures, we will be using XML messages (platform independent) for communications.

Wordpress provides XML-RPC based webservice for communication with different technologies and application which can be found on the root directory with the name xmlrpc.php.

ASP .NET requires a library XML-RPC.NET to impliment and communicate xmlrpc based webservices.

Pre-Requisites

You are required to have the following installed before you can jump into the code, they are:

1. A wordpress blog, you can download it from here.
2. An XML-RPC .net library, which can be downloaded from here.

I will be assuming that you have your blog ready and have the admin privileges to access and update any settings you may require to change.

Using the code

Create a new website, add 2 textboxes and a button onto the form having the following properties

Textbox1 : Name -> txtTitle

Textbox2 : Name -> txtDescription

Now extract the downloaded zip file containing xmlrpc .net library and add the reference to CookComputing.XmlRpcV2.dll in the bin folder.

Now add the following code

 public struct blogInfo
    {
        public string title;
        public string description;
    }

    public interface IgetCatList
    {
        [CookComputing.XmlRpc.XmlRpcMethod("metaWeblog.newPost")]
        string NewPage(int blogId, string strUserName, string strPassword, blogInfo content, int publish);
    }

We are done with creating an struct for blog info and an interface for the WordPress API.

Now add the following code to the button click event.

        blogInfo newBlogPost = default(blogInfo);
        newBlogPost.title = txtTitle.Text;
        newBlogPost.description = txtPost.Text;

        IgetCatList categories = (IgetCatList)XmlRpcProxyGen.Create(typeof(IgetCatList));
        XmlRpcClientProtocol clientProtocol = (XmlRpcClientProtocol)categories;

        clientProtocol.Url = "http://localhost:8080/wordpress/xmlrpc.php"; //your blog address comes here
        string result = null;

        result = "";

        try
        {
            result = categories.NewPage(1,
                                "admin", //your blog admin user id
                                "Admin", //your blog admin password
                                newBlogPost,
                                1);

            txtPost.Text = "";
            txtTitle.Text = "";
        }
        catch (Exception ex)
        {
            MessageBox.Show(ex.Message);
        }
