To check whether the string value has numeric value or not in C#

Question

I am having an string like this

string str = \"dfdsfdsf8fdfdfd9dfdfd4\"

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

Answer 1

If you're going to loop through the string, DON'T use int.TryParse... that's way too heavy. Instead, use char.IsNumber();

example:

foreach (char c in myString)
    if (char.IsNumber(c))
        return true;
