I need to check whether the string contains number by looping through the array.

Answer 1

in C# 2.0, try this:

        string str = "dfdsfdsf8fdfdfd9dfdfd4";

        for (int i = 0; i < str.Length; i++)
        {
            int result;
            if (int.TryParse(str[i].ToString(), out result))
            {
                //element is a number            
            }
            else
            {
                // not a number
            }
        }
