Hi there, is there a way i can make my system accept char[] values like '-' in the form of an int value.

I have an int place holder, but when there is no int value supplied, i want to put '-' in that place of the int. Is this really possible?

Thanks in advance
Martin

no this is not posible to do. one thing you could do is make you int nullable and then if the int is null then use display the value "-".

C#

int? myIntValue = null;
        public string GetIntValue()
        {
            return myIntValue.HasValue ? myIntValue.Value.ToString() : "-";
        }

Hope this helps

Solution 2

int specialValue = '-';

specialValue will now contain the numeric equivalent of the '-' character which is hex 0x2D or decimal 45.

Solution 3

You can use nullable types as an int.
When there is no value supplied, set the int variable to null, and then while displaying the null, show a '-'.
e.g.

int? i = null;
Console.WriteLine(i==null?"-":i.ToString();
