Can I store LINQ query result in an array?

This is the code using LINQ, it stores the values into list

string StringRegex = "\"(?:[^\"\\\\]|\\\\.)*\"";

        Dictionary<string, string> dictionaryofString = new Dictionary<string, string>()
        {
            {"String", StringRegex}
        };

 var matches = dictionaryofString.SelectMany(a => Regex.Matches(input,a.Value)
        .Cast<Match>()
        .Select(b =>
                new
                {
                    Index = b.Index,
                    Value = b.Value,
                    Token = a.Key
                }))
        .OrderBy(a => a.Index).ToList();
        for (int i = 0; i < matches.Count; i++)
        {
            if (i + 1 < matches.Count)
            {
                int firstEndPos = (matches[i].Index + matches[i].Value.Length);
                if (firstEndPos > matches[(i + 1)].Index)
                {
                    matches.RemoveAt(i + 1);
                    i--;
                }
            }
        }
foreach (var match in matches)
        {
            Console.WriteLine(match);
        }

Can it not be stored into Array? Where I can display only item I want. Just like here the output is {Index=, Value=, Token=} Meanwhile I want the output that be of just "Value" "Token" index not needed.

You can use ToArray instead. But List gives you the desired array functionality already, you can access an item by its index.

var exampleQuery = select c from componentsDemo;
var list = exampleQuery.ToList();
var secondElement = list[1]; // <- demo only, there could be an exception thrown, if there's less than two elements in the list

EDIT: as I can see from your comments, you need this:

foreach (var match in matches)
{
   Console.WriteLine(match.Value + ", " + match.Token); 
}
