if (videos != null)
{
foreach(HtmlAgilityPack.HtmlNode video in videos)
{
linkCounter += 1;
video.InnerHtml = video.InnerHtml + "[Video - To play, press Ctrl+" + linkCounter.ToString() + "]";
dcLinks.Add(linkCounter, video); // error
}
}
Try another instruction:
dcLinks[linkCounter] = video;
However, if you do not want to replace the existing items, then maybe you should clear dcLinks and restart linkCounter from zero.
Probably it is much better to use a List instead of Dictionary.
It depends on details that are not explained.
But my actual prob is I need to upload a set of video link one after another in my tool and if i am post the !st link it is accepting and whenever I post the second video link then I am getting this error
For Reference code
public static class MDU
{
public static string H(string text,ref int linkCounter, ref int excCounter, ref Dictionary<int, HtmlAgilityPack.HtmlNode> dcLinks)
{
HtmlAgilityPack.HtmlDocument doc = new HtmlAgilityPack.HtmlDocument();
doc.LoadHtml("<html>" + PreProcess(text) + "</html>");
if (doc.DocumentNode == null)
{
return string.Empty;
}
var videos = doc.DocumentNode.SelectNodes("//a[contains(@href, 'vimeo')]");
if (videos != null)
{
foreach(HtmlAgilityPack.HtmlNode video in videos)
{
linkCounter += 1;
video.InnerHtml = video.InnerHtml + "[Video - To play, press Ctrl+" + linkCounter.ToString() + "]";
dcLinks.Add(linkCounter, video);
}
}
var elinks = doc.DocumentNode.SelectNodes("//e");
if (elinks != null)
{
excCounter += 1;
}
return doc.DocumentNode.InnerText;
}
If you want to accumulate the links one after another, then maybe a List collection is suitable, because it has the Add function, and the items can be accessed by index.
Thank you its working now
