unable to validate multiple condition in AssertThat validation

[makwana8055]

    [Display(ResourceType = (typeof(DisplayNamesForWeb)), Name = "SuggestedRequest")]
    public decimal? Amount1 { get; set; }

    [Display(ResourceType = (typeof(DisplayNamesForWeb)), Name = "OriginalRequest")]
    [AssertThat(@"Amount1 != null && Amount2 != null  && Amount2 <= Amount1", ErrorMessageResourceType = typeof(ErrorMessagesForWeb), ErrorMessageResourceName = "Amount2 must be less than or equal to Amount1")]
    public decimal? Amount2 { get; set; }

• If Amount1 and Amount2 has value then i want to check that amount2 should not be greater than amount1.

[karim-ting]

why not use separate assert annotations and give them different priority values as required?

[tempel3]

"Amount1 == null || Amount2 == null || Amount2 <= Amount1" that should do it. It Amount1 hat no value -> true, if Amount2 has not value -> true and it Amount2 <= Amount1 -> true.

That way it will only check if Amount1 and Amount2 are set.

Is it what you need?
