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

What about a regular expression:

bool val = System.Text.RegularExpressions.Regex.IsMatch(str, @"\d");

Answer 2

Combining parts of Kamals answer and Tristars answers give...

str.Any(char.IsNumber)

which I think is the most succinct and readable way, instead of a regex
