Better annotation of data for one decimal (18.2)
advertisements
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 property, inside my asp.net MVC web application ?
There is no explicit data annotation for a decimal so you need to use two separate ones to add constraints.
Two Decimal Points
[RegularExpression(@"^\d+\.\d{0,2}$")]
This regular expression will make sure that the property has at most two decimal places.
Max 18 digits
[Range(0, 9999999999999999.99)]
Assuming you aren't accepting any negative numbers. Otherwise, replace 0 with -9999999999999999.99.
Result
[RegularExpression(@"^\d+\.\d{0,2}$")]
[Range(0, 9999999999999999.99)]
public decimal Property { get; set; }
