Post Image With Message in Twitter Tweet in .NET Framework 3.5

Step 1

 

Add ASP.Net Web Service in 4.0.

 

Step 2

 

For Twitterizer reference use the following procedure:

• Go to "Tools"
• Select "Library Package Manager"
• Select the "Package Manager Console" then select the source as a Nugget official package source and select your project name in the default project
• Execute command
• Install-Package twitterizer -Version 2.4.1

Step 3

 

Check the code behind the web service Service1.asmx.cs

public class Service1 : System.Web.Services.WebService
{
    string requestToken = string.Empty;
    string pin = string.Empty;
    string oauth_consumer_key;
    string oauth_consumer_secret;
    [WebMethod]
    public string HelloWorld()
    {
        return "Hello World";
    }
    [WebMethod]
    public OAuthTokenResponse function1(string x)
    {
        OAuthTokenResponse reqToken = null;
        oauth_consumer_key = "abcdefghijk";
        oauth_consumer_secret = "1234567890123213232";

        if (HttpContext.Current.Request["oauth_token"] == null)
        {
            reqToken = OAuthUtility.GetRequestToken(oauth_consumer_key, oauth_consumer_secret, x);
        }

        return reqToken;
    }
    [WebMethod]
    public bool function2(string requestToken, string pin)
    {
        oauth_consumer_key = "abcdefghijk";
        oauth_consumer_secret = "1234567890123213232";
        var tokens = OAuthUtility.GetAccessToken(oauth_consumer_key, oauth_consumer_secret, requestToken, pin);
        OAuthTokens accesstoken = new OAuthTokens()
        {
            AccessToken = tokens.Token,
            AccessTokenSecret = tokens.TokenSecret,
            ConsumerKey = oauth_consumer_key,
            ConsumerSecret = oauth_consumer_secret
        };
        //~/img/th2.jpg
        byte[] photo = File.ReadAllBytes(@"D:\MVC_GROUP_DEAL\WebApplication1\WebService1\th22.jpg");
        TwitterResponse<TwitterStatus> response = TwitterStatus.UpdateWithMedia(accesstoken, "img", photo);
        if (response.Result == RequestResult.Success)
        {
            return true;
        }
        else
        {
            return false;
        }
    }
}

Step 4

 

Add a new project. Create an ASP.Net web application in Framework 3.5. Add a default page. In the code behind add the following code.

using Twitterizer;
using WebApplication1.localhost;
protected void Page_Load(object sender, EventArgs e)
{
    Service1 oService1 = new Service1();

    if (Request["oauth_token"] == null)
    {
        WebApplication1.localhost.OAuthTokenResponse oaToken = (WebApplication1.localhost.OAuthTokenResponse)oService1.function1(Request.Url.AbsoluteUri);
        HttpContext.Current.Response.Redirect(string.Format("http://twitter.com/oauth/authorize?oauth_token={0}", oaToken.Token));
    }
    else
    {
        string requestToken = Request["oauth_token"].ToString();
        string pin = Request["oauth_verifier"].ToString();
        bool i = oService1.function2(requestToken, pin);
        Response.Write("Message Posted ");
    }
}

Step 5

 

It will ask for a Twitterizer reference; for that use the following procedure:

• Go to Tools
• Select "Library Package Manager"
• Select the Package Manager console then select the source as a Nugget official package source and select your project name in the default project
• Execute command
• Install-Package twitterizer -Version 2.3.1

Step 6

 

Rebuild all and see the output.
