MVC验证 - 非必填字段在提交表单前被强制填写

Question

我认为在提交表单之前需要填写以下字段。

VIEW：

<div class="col-md-4"> 
    @Html.EditorFor(model => model.BusinessPhone, new { htmlAttributes = new { @class = "form-control boldgray", @placeholder = "Business Phone" } }) 
</div> 

<div class="col-md-4"> 
    @Html.EditorFor(model => model.MobilePhone, new { htmlAttributes = new { @class = "form-control boldgray", @placeholder = "Mobile/Alternative" } }) 
</div> 

MODEL：

[DisplayName("Home Phone")] 
[Required] 
public int HomePhone { get; set; } 

[DisplayName("Business Phone")] 
public int BusinessPhone { get; set; } 

[DisplayName("Mobile Phone")] 

这些字段标在我的数据库为 “允许空值”，并没有[必需]数据标注在我的模型。为什么在提交表格之前需要他们？

Answer 1

也许尝试使用可为空的电话号码？

如：

[DisplayName("Business Phone")] 
     public int? BusinessPhone { get; set; }
