数据注释到有效的有效整数值

Question

我是MVC的新手。我试图仅为整数验证文本框值。

这是我迄今为止尝试过的属性和数据注释

    [Required(ErrorMessage = @"Must Enter EOT Months")]
    [RegularExpression("([0-9]+)", ErrorMessage = @"EOT Months ")]
    [Range(0, int.MaxValue, ErrorMessage = @"EOT Months must be numeric and a whole number")]
    public int PayoutEOTMths
    {
        get { return DisposalConstant.PayoutEOTMths; }
        set { DisposalConstant.PayoutEOTMths = value; }
    }

但每当我输入6.5等值时。它给我提供了

的默认验证消息

•The value '6.5' is not valid for PayoutEOTMths.
