If you noticed Media under entities not available in above 2 and when i tried to call below snippet gives me null reference error
MediaUrl = (from user in tweet["entities"]["media"]
select new mediaUrl
{
shortUrl = (string)user["url"],
longUrl = (string)user["expanded_url"],
url = (string)user["media_url"],
start = user["indices"][0].ToString(),
end = user["indices"][1].ToString(),
mediaType = (string)user["type"],
}).ToList()
Same code work for Entities/URL, Hashtags and mentions but not for Media.
Also tried this -> Get JSON object node but still getting null reference exception.
Finally got working. Not appropriate solution but works for me.
I created separate method for parsing Media. Passed Entity as string and in that method i checked is EntityString.Contains Media or not. If yes, then parse media json else returned null. See below Snippet.
if (Entities != string.Empty)
{
if (Entities.Contains("\"media\":"))
{
JObject searchResult = JObject.Parse(Entities);
returnMedia = (from user in searchResult["media"]
select new mediaUrl
{
shortUrl = (string)user["url"],
longUrl = (string)user["expanded_url"],
url = (string)user["media_url"],
start = user["indices"][0].ToString(),
end = user["indices"][1].ToString(),
mediaType = (string)user["type"],
}).ToList();
}
}
This works for me. If you have any better solution then Please let me know.
