Let’s say I have the class Wallet:
public class Wallet
{
public double Min { get; set; }
public double Max { get; set; }
public double Value { get; set; }
}
And let’s say that the data is read from a database.
The user is able to modify Value from the UI.
I want to validate it somehow, so my initial thought was:
[Range(Min, Max, ErrorMessage = "The value is outside of bounds.")]
public double Value { get; set; }
But an error is thrown: Cannot access non-static property in a static context attribute.
Is there a workaround or do I have to create a custom validation?
Context: WPF MVVM application, C#
>Solution :
You could move that validation to the setter, and throw the exact validation exception that the attribute class throws if any validation erros occur.
