if statement

if i have the following array:

Code:

---

private string[] digits = { "0", "1", "2", "3", "4", "5", "6", "7", "8", "9" };

---

and i then want to check if a string contains any of these numbers, could i do something like this:

Code:

---


String test ="1+2+3";

if(test equals any of the digits in 'digits')
{
    // Do stuff
}

---

i would use regular expressions

you need to add the following

Code:

---

using System.Text.RegularExpressions;

---

the actual code would be:

Code:

---


String strInput = "Your input text!!!11";
string strPatern = "[0-9]";
Match myMatch = Regex.Match(strInput, strPatern);
if(myMatch.Success)
{
//dostuff
}

---
