Is there any way to implement LinkedIN API by using C#,VB.NET. We need to call profile , companies ,Jobs etc API of linked in using mentioned technologies.
Linkedin have a REST based API - http://developer.linkedin.com/docs/DOC-1258
You can create a HttpWebRequest, pointed at a REST endoint, and parse the response however you wish.
// Create the web request
HttpWebRequest request = WebRequest.Create("http://api.linkedin.com/v1/people/~/connections/") as HttpWebRequest;
// Get response
using (HttpWebResponse response = request.GetResponse() as HttpWebResponse)
{
// Get the response stream
StreamReader reader = new StreamReader(response.GetResponseStream());
// Console application output
Console.WriteLine(reader.ReadToEnd());
}
