isCryptSolution

My solution:

bool isCryptSolution(string[] crypt, char[][] solution) 
{
    var words = new List<decimal>();
    foreach (var word in crypt)
    {
        decimal wordsum = 0;
        for (var ci = 0; ci < word.Length; ci++)
            foreach (char[] t in solution)
            {
                if (word[ci] != t[0]) continue;
                if (word[0] == t[0] && t[1] == '0' && word.Length != 1) return false;
                wordsum += Convert.ToInt32(t[1].ToString()) *
                           Convert.ToDecimal(Math.Pow(10, word.Length - 1 - ci));
                break;
            }

        words.Add(wordsum);
    }

    return words[2] == words[0] + words[1];
}
