[Range(0,120)]
public int QtyOnHand { get; set; }
如何添加错误消息来说出所需的范围？
RangeAttribute有一个可以设置的ErrorMessage：[Range (0, 120, ErrorMessage = "Quantity on hand must be between {1} and {2}.")]
public int QtyOnHand { get; set; }
通过使用{1}和{2},您不必在数字更改时不断更改字符串. {0}用于该字段的名称.这可以伴随DisplayNameAttribute：
[DisplayName ("Quantity on Hand")]
[Range (0, 120, ErrorMessage = "{0} must be between {1} and {2}.")]
public int QtyOnHand { get; set; }
