One thing that has bothered me about C# since its release was the lack of a generic IsNumeric function. I know it is difficult to generate a one-stop solution to detrmine if a value is numeric.

I have used the following solution in the past, but it is not the best practice because I am generating an exception to determine if the value is IsNumeric:

public bool IsNumeric(string input)
{
    try
    {
        int.Parse(input);
        return true;
    }
    catch
    {
        return false;
    }
}

Is this still the best way to approach this problem or is there a more efficient way to determine if a value is numeric in C#?
