What are the ways to post a tweet to twitter with asp.net c#? [duplicate]

With Twitter's new OAuth interface, their API is now many times more complex than what it was. And I haven't even looked at Facebook's API yet.
What I'm wondering if there is a method that employs some higher-level, existing code or interfaces to make this a simpler task.
All I want to be able to do is initiate a Twitter tweet or Facebook share on the user's behalf and be able to control the initial text of those messages, from an ASP.NET application.
I found some similar questions on SO, but they had no answers.
EDIT: I know there are things like AddThis and ShareThis, but I need something that will give me control over the default message. It must contain a link with a code that is specific to the current user.

Twitter Integration...
For making Tweets from an ASP.NET application on users' behalf, check out Twitterizer. It's a free, open-source project for integrating with Twitter from .NET applications.
I agree that using OAuth can be a bit daunting, but the Twitterizer API wraps up most of the complexity. I've written an article on using Twitterizer in an ASP.NET application that you may be interested in: Integrating Twitter Into An ASP.NET Website Using OAuth. After reading the article, download the code sample at the end, which is a working demo showing how to use Twitterizer to post a tweet from an ASP.NET website.
Facebook Integration...
For integrating with Facebook, chcek out the Facebook Developer Toolkit. Like Twitterizer, it's an open-source, free API and should get you going in the right direction.
Happy Programming!

After looking around for a while, I found sharethis.com. They have various share buttons you can add to your site that send Twitter tweets, Facebook shares, etc.
It looks like it also supports options to control the URL, so I could modify this to include whatever URL I need.
I haven't yet figured out if I can control the default message text. I'm looking into that.
But it seems like this is probably the simplest way to accomplish what I want.

This is probably what you're after for twitter: https://twitter.com/about/resources/buttons#tweet
Let's you configure a button (or URL to redirect to) that starts the user off with some default text. The user can change the text before they post.
Don't know about facebook.

Twitter Integration:
Check this code and link/article simple and easy :
protected void btnTweet_Click(object sender, EventArgs e)
{
string oauthAccessToken = Session["twtoken"].ToString();
string oauthAccessTokenSecret = Session["twsecret"].ToString();
OAuthHelper oauthhelper = new OAuthHelper();
oauthhelper.TweetOnBehalfOf(oauthAccessToken, oauthAccessTokenSecret, txtTweet.Text);
if (string.IsNullOrEmpty(oauthhelper.oauth_error))
Response.Write("Twit Posted Successfully");
else
Response.Write(oauthhelper.oauth_error);
}

How to retrieve signed user docs from docusign?

I have completed the setup of embedded signing using docusign for a C# MVC site. I would like to retrieve the signed docs from docusign in the form of a link - like click on link and access the docs(without having to sign in docusign) to see if the user has signed or not etc or download it as a pdf on my site. Is there a way to do this via a rest call may be ? I tried this REST call from the documentation - /restapi/{apiVersion}/accounts/{accountId}/envelopes/{envelopeId}/views/correct .. but it did not really get me what I wanted.
Thanks much!

Yes you can easily retrieve (download) the envelope documents through the API. One of the API Walkthroughs show code in how to do this in 6 different languages, and if you want the raw REST(ful) info you can check out this page from the API docs.
For the API Walkthroughs see #6 labeled "Get Document List & Download Docs":

// code which i have used
string APIKey = ConfigurationManager.AppSettings["API_Key"];
string APISecret = ConfigurationManager.AppSettings["API_Secret"];
Facebook.Session.ConnectSession connectsession = new Facebook.Session.ConnectSession(APIKey, APISecret);
if (connectsession.IsConnected())
{
Facebook.Rest.Api api = new Facebook.Rest.Api(connectsession);

Facebook Graph C# SDK Ver 6.0: Unable to create event on App's Page
please help me to start facebook api integration in my desktop based app using wpf. some body asked to use graph api but i have doubt whether this will supprot for c# . am struk to start my step on facebook integration.

Graph Api is fully supported in C# because it is based on rest and you can call rest service through C# code, obviously url calling is different from method calling, In graph api you can call url and parse its response. I would recommend to go with graph api, Facebook has not provided the C# SDK, its a open source library maintained by open source community, however graph api help is directly provided by Facebook.
Check here and here to know how to call graph api through C#

Obtaining Photos and Albums from Facebook using C#

I'm trying to parse through and obtain my (my personal account not my app) albums from Facebook using the Facebook C# SDK. My goal is to grab the 10-12 most recent photos on my account. However, I understand I have to grab the albums first.
So, I've tried numerous things and ended up with the following url which returns a 400 Bad Request:
https://graph.facebook.com/{my_user_id}/albums?access_token={my_access_token}
The token was obtained by calling:
https://graph.facebook.com/oauth/access_token?client_id={0}&client_secret={1}&grant_type={2}&scope={3}
Any ideas why I'd be getting the 400?

When using grant_type = client_credentials you're requesting the an app access token. This will allow you to do various administrative actions for your application. See App Login in http://developers.facebook.com/docs/authentication/.
However, when using the user-parts of the Graph Api you need to perform a User Login using the oAuth Dialog. There are different ways of doing this such as with the Javascript SDK which should be straightforward to use.
I've not found a nice way of doing this in a standalone web app using Facebook C# SDK without the Javascript SDK (it's easy in a canvas app using the CanvasAuthorize attribute).
Here's an example of how to do it i a WinForms app http://blog.prabir.me/post/Facebook-CSharp-SDK-Writing-your-first-Facebook-Application.aspx. It might work in a Asp.Net app if you could use the WebBrowser control. I've tried with WebClient but didn't have any luck.
Update
By looking at the sample here http://facebooksdk.codeplex.com/SourceControl/changeset/view/534da45e108f#Samples%2fCSMvcWebsite%2fControllers%2fHomeController.cs it looks like you should be able to use the FacebookAuthorize attribute in a standalone site.

Error code 400 means that the request was not correctly formatted. Verify that that the Final URL looks OK and try it in a browser.
The request could not be understood by
the server due to malformed syntax.
The client SHOULD NOT repeat the
request without modifications.
I.e. that you try the following https://graph.facebook.com/someuser/albums?access_token=1234 You would pre presented with the following:
{
"error": {
"type": "OAuthException",
"message": "Invalid OAuth access token."
}
}
If you provide an OK token and a real user, the result will probably look a bit different, but in your case you get a 400 because there is something wrong with the request.
