I am trying to trim an item called Input (object form .json file) which is inside of a foreach loop.
The code I have at the moment is:
List<string> dhurl = new List<string>();
foreach (JObject item in jArray)
{
dhurl.Add("https://" + (string)item.SelectToken("Input");
}
input adds "sm-tiktoktrends.com", I want it to only add "tiktoktrends.com", how can I use trim to remove "sm-"?
*To clarify all Input objects will need sm- removed
The question is not clear if all values start with "sm-". If so, and you're willing to use LINQ:
List<string> dhurl = jArray.Select(item => "https://" + ((string)item.SelectToken("Input")).Substring(3)).ToList();
Otherwise, I might do it something like this:
List<string> dhurl = jArray
.Select(item => (string)item.SelectToken("Input"))
.Select(item => "https://" + (item.StartsWith("sm-") ? item.Substring(3) : item))
.LoList();
New example based on comment below:
List<string> dhurl = jArray
.Select(item =>
string.Format(
"https://{0}/?sig={1}",
((string)item.SelectToken("Input")).Substring(3),
(string)item.SelectToken("Signature")
))
.LoList();
You, probably, should use Substring(...) together with StartsWith(...) instead of Trim(...):
string input = item.SelectToken("Input").ToString();
if (input.StartsWith("sm-"))
{
input = input.Substring(3);
}
dhurl.Add("https://" + input);
