How to find out if a string contains only numbers or also letters

Hey,

we want to set up a rule that checks in the Business Partner Master Data on ADD and/or UPDATE if the BP Code is numeric or if it contains letters.

In our philosophy only numbers are allowed.

How can I check if the string contains only numbers and not letters also ?

Thanks for a short answer.

Hello Heiko,

Regular expressions would normally be used for such things but in this case you can use the simpler TryParse static method of the Int32 class:

string cardcode = "123456";

bool isNumeric = false;

int tmp;

if (int.TryParse(cardcode, out tmp))

{

isNumeric = true;

}

Regards,

Anders
