In my View Model I have a property:
[Required]
[MaxLength(4)]
[DisplayName("CVC")]
public int BillingCvc { get; set; }
In my view I use it like so:
@Html.TextBoxFor(x => x.BillingCvc, new { size = "4", maxlength = "4" })
When I post the form I get this error message:
Unable to cast object of type 'System.Int32' to type 'System.Array'.
However, if I change the property to string instead of int, I don't get the error. Declaring it as int allows the client validator to check if the field contains non numbers.
The issue is your use of MaxLength
with a type of int
.

edit: you;re probably looking for Range(int,int)
