Combining these two Regular Expressions into one

Question

I have the following in C#:

public static bool IsAlphaAndNumeric(string s)
{
    return Regex.IsMatch(s, @\"[a-zA-Z]+\") 
        && Regex.IsMatch(s,         


        

Answer 1

For C# with LINQ:

return s.Any(Char.IsDigit) && s.Any(Char.IsLetter);
