c＃mvc DataType.MultilineText with Required and accept enter

Question

我的模型带有地址字段

[DataType(DataType.MultilineText)]
[Display(Name = "Address")]
[Required(ErrorMessage = "Address is required.")]
public string Address { get; set; }

我应该有一个必需的textarea，我想接受退货。渲染HTML似乎是正确的

<textarea name="Address" id="Address" rows="2" cols="20" 
          data-val-required="Address is required." data-val="true" 
          data-val-length-max="1024" 
          data-val-length="Address must be under 1024 chars.">
</textarea>

但该字段不是必需的，我可以输入return。 有什么建议？提前谢谢
