Answer 1

string result = string.Join(",", 
                    Enumerable.Range(0, terms.GetLength(0))
                       .SelectMany(i => Enumerable.Range(0, terms.GetLength(1))
                                           .Select(j => terms[i, j])));

EDIT: Non-LINQ version:

    List<string> result = new List<string>();
    for (var i = 0; i < terms.GetLength(0); i++)
    {
        for (var j = 0; j < terms.GetLength(1); j++)
        {
            result.Add(terms[i, j]);
        }
    }
    string output = string.Join(",", result);
