Best Data annotation for a Decimal(18,2)

Question

I have a column inside my sql server 2008 wih type of Decimal(18,2). But on entity framework what is the best data annotation validation I can apply to this pro

Answer 1

I think @jumpingcode's answer can be combined into one RegularExpressionAttribute.

[RegularExpression(@"^(0|-?\d{0,16}(\.\d{0,2})?)$")]
public decimal Property
{
    get;
    set;
}

This can be used for any precision and scale. The 16 is replaced by precision - scale and the 2 is replaced by the scale. The regular expression should match numbers entered like ###, 0.##, .##, 0, and ###.## as well as negative values.

Answer 2

Im using almost excplusively (b/c it's simple and works)

[Range(typeof(decimal), "0", "1")]
public decimal Split { get; set; }

Then if I need to convert back to double I add a conversion

(double)model.Split
