Question

I would like to know whether there is any method in C# that takes out all the content of a string until the first number is encountered. Example:

string myString = "USD3,000";
myString = SomeMethod(myString, [someparameters]);
myString -> "3,000"

Answer 1

Not inbuilt, but you could just use either a regex, or IndexOfAny:

static void Main()
{
    string myString = "USD3,000";
    var match = Regex.Match(myString, @"[0-9].*");
    if(match.Success)
    {
        Console.WriteLine(match.Value);
    }
}

or

static readonly char[] numbers = "0123456789".ToCharArray();
static void Main()
{
    string myString = "USD3,000";
    int i = myString.IndexOfAny(numbers);
    if (i >= 0)
    {
        string s = myString.Substring(i);
        Console.WriteLine(s);
    }
}
