Question

Goal:
Validate input data in my e-formulary.

Question:
What syntax code (dataannotations) do I need to ensure that data is int or decimal?

Answer 1

If you are recieving your data from an input box, you can use a TryParse on your data. e.g.

decimal dec;
if(decimal.TryParse(YourInput.Text, out dec))
{
   // Valid Decimal
}
else { // Invalid }

…Same goes for an int, with int.TryParse();
