				This technical tip allows developers to get selected link on a page in PDF file using Saaspose.Pdf REST API in your .NET applications. Saaspose.Pdf is a REST API to create, edit & manipulate PDF files. It also convert PDF file to DOC, DOCX, HTML, XPS, TIFF etc. It is platform independent REST API & working with web, desktop, mobile or cloud applications alike. Some important steps for performing this task are to build URI to get selected link on a page, Parse the json string to JObject, Deserializes the JSON to an object and the classes used in this process are given in detail.

string strURI = "http://api.saaspose.com/v1.0/pdf/input.pdf/pages/1/links/1";
string signedURI = Sign(strURI);
Stream responseStream = ProcessCommand(signedURI, "GET");
StreamReader reader = new StreamReader(responseStream);
string strJSON = reader.ReadToEnd();
//Parse the json string to JObject
JObject parsedJSON = JObject.Parse(strJSON);
//Deserializes the JSON to a object. 
PdfLinkResponse pdfLinkResponse = JsonConvert.DeserializeObject(parsedJSON.ToString());
Link tempLink = pdfLinkResponse.Link;
	//Here is the BaseResponse class
	public class BaseResponse
 	{
	public BaseResponse() { }
	public string Code { get; set; }
	public string Status { get; set; }
	}
	//Here is the PdfLinkResponse class
	public class PdfLinkResponse : BaseResponse
	{
	public PdfLinkResponse() { }
	public Link Link { get; set; }

	public class LinkResponse

	public string Rel { get; set; }
	public string Title { get; set; }
	public string Type { get; set; }
	}
	//Here is the Link class
	public class Link
	{
	public Link() { }
	public LinkActionType ActionType { get; set; }
	public string Action { get; set; }
	public LinkHighlightingMode Highlighting { get; set; }

	Push,
	Toggle
	}
	//Here is the Color class
	public class Color
	{
	public Color() { }
	public List Links { get; set; }
	public int A { get; set; }
	public int B { get; set; }
	public int G { get; set; }
	public int R { get; set; }

	 Dim signedURI As String = Sign(strURI)
	 Dim responseStream As Stream = ProcessCommand(signedURI, "GET")
	 Dim reader As New StreamReader(responseStream)
	 Dim strJSON As String = reader.ReadToEnd()
	 'Parse the json string to JObject
	 Dim parsedJSON As JObject = JObject.Parse(strJSON)
	 'Deserializes the JSON to a object.
	 Dim pdfLinkResponse As PdfLinkResponse = JsonConvert.DeserializeObject(Of PdfLinkResponse)(parsedJSON.ToString())
	 Dim tempLink As Link = pdfLinkResponse.Link
