如何验证 Asp.net 中的 integer 是否属于具有内置验证的多个间隔（或有异常的范围）？

Question

I have an integer that can fall in range from -1000 to 1000 but cannot be zero. I cannot find any built-in validation that can fix this:

• Range can be only used once and does not allow exceptions or intervals
• Required does not allow zero validation

I know I can just write a custom attribute, but was wondering if I can achieve this in a simple way that I cannot find.

And ideally not regular expression, though I guess that would be the easiest way.

Answer 1

You cannot exclude the value from a range. Using ranges is as simple as that (but it DOESN'T support any excluding):

[Range(-1000, 1000)]
public int Amount {get; set;}

But you can easily achieve it writing validation using FluentValidation
