城堡驗證器如何驗證是否小於/大於或等於

Question

我看到ValidateIsLesser和ValidateIsGreater屬性。但是如果我想要做一個ValidateIsLesserOrEqual和/或ValidateIsGreaterOrEqual。我是否需要編寫這些自定義屬性，或者是否有預構建的功能，因此我很難找到？

[ValidateNonEmpty] 
[ValidateDate] 
[ValidateIsLesser(IsLesserValidationType.Date, "EndDate", "Start Date must be before End Date.")] 
public DateTime StartDate { get; set; } 

[ValidateNonEmpty] 
[ValidateDate] 
[ValidateIsGreater(IsGreaterValidationType.Date, "StartDate", "End Date must be after the Start Date.")] 
public DateTime EndDate { get; set; } 

Answer 1

可以使用ValidateSelf屬性，並提供自己的驗證爲OrEqual比較：

[ValidateNonEmpty] 
[ValidateDate] 
public DateTime StartDate { get; set; } 

[ValidateNonEmpty] 
[ValidateDate] 
public DateTime EndDate { get; set; } 

[ValidateSelf] 
public void ValidateDate(ErrorSummary errors) 
{ 
    if (StartDate >= EndDate) 
     errors.RegisterErrorMessage("StartDate", "Start date must be earlier than end date."); 
}
