How to extract all anchor tags using HtmlAgilityPack?

I would like to be able to extract all the anchor tags from the bottom input string, however my current function, is only able to extract the last a href tag, as I would like to extract all of the anchor tags, under the heading 'picks'.

for example, here is my input feed going into bottom variable:

C#

string bottom = "<P align=justify>picks<BR>
<A href="/Article.aspx?article=froth&PUB=250&ISS=22787&SID=51610" name="" target=_blank>froth</A>
: Text...<BR>
<A href="/Article.aspx?article=Bouncing back&PUB=250&ISS=22787&SID=51603" name="" target=_blank>Bouncing back</A>
: Text...<BR></P>"

Updated server code:

C#

    var result = "";

    while (reader.Read())
    {
        string bottom = reader.GetString(1);

        string price = "";
        if (bottom.ToLower().Contains("picks"))
        {

            price = bottom.Substring(bottom.IndexOf("picks"), 5);

            HtmlDocument html = new HtmlDocument();

            html.LoadHtml(bottom);
            var anchors = html.DocumentNode.Descendants("A");

                foreach (var a in anchors)
                {
                    result = a.OuterHtml;
                }
          }

       result.ToString();

    }
    return article = result;
}

The following line of code is not allowing me add extract all() property, as it keeps throwing me this error - No overload for method 'All' takes 0 arguments

C#

if (anchors.All())

any further guide, as to where I may be going wrong would be very much appreciated.
Thanks

The All method[^] verifies that all elements in the source collection match a particular predicate. It doesn't make any sense to call it without a predicate, so there isn't an overload to do that.

It's possible that you meant to call the Any method[^], which does have an overload without a predicate. However, given the code you've posted, you don't need to call any method; just use the foreach loop:

C#

var anchors = html.DocumentNode.Descendants("A");
foreach (var a in anchors)
{
   ...
}

EDIT:
To return all of the anchors, you'll either need to change the method to return a list of strings, or combine the strings using a separator:

C#

var result = new List<string>();

while (reader.Read())
{
    string bottom = reader.GetString(1);
    int index = bottom.IndexOf("picks", StringComparison.OrdinalIgnoreCase);
    if (index != -1)
    {
        var html = new HtmlDocument();
        html.LoadHtml(bottom);

        var anchors = html.DocumentNode.Descendants("A");
        foreach (var a in anchors)
        {
            result.Add(a.OuterHtml);
        }
    }
}

// To return a list of strings:
return result;

// To return a single string with each result on a new line (.NET 4.0 or higher):
return string.Join(Environment.NewLine, result);

// To return a single string with each result on a new line (.NET 3.5 or earlier):
return string.Join(Environment.NewLine, result.ToArray());
