Sample Code for Get Selected Link on a Page in PDF File
[C# Code]
//build URI to get selected link on a page
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.

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; }
}
//Here is the LinkResponse class
public class LinkResponse
{
public string Href { get; set; }
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; }
public Color Color { get; set; }

public int A { get; set; }
public int B { get; set; }
public int G { get; set; }
public int R { get; set; }
}
