基于字段值的自定义显示注释

Question

我有一个基于字段值的视图，必须显示自定义标签。

视图模型：

public class CreateAdViewModel 
{ 
    public int Operation_Id { get; set; } 

    [Display(ResourceType = typeof(HeelpResources), Name = "AdViewModel_Price_Label")] 
    public decimal Price { get; set; } 
} 

查看：

<div id="price"> 
     @Html.DisplayNameFor(m => m.Price) 
     @Html.TextBoxFor(m => m.Price) € 
     @Html.ValidationMessageFor(m => m.Price) 
    </div> 

我想显示：

"Price: " if Operation_Id = 1 (For the Sale of a Car) 

而且

"Price Up To: " if Operation_Id = 2 (For someone looking for a car until value XX €)

怎么样2个属性：

public class CreateAdViewModel 
{ 
    public int Operation_Id { get; set; } 

    [Display(ResourceType = typeof(HelpResources), Name = "AdViewModel_Price_Label")] 
    public decimal? Price { get; set; } 

    [Display(ResourceType = typeof(HelpResources), Name = "AdViewModel_MaxPrice_Label")] 
    public decimal? MaxPrice { get; set; } 
} 

和视图里面：

<div id="price"> 
    @if (Operation_Id == 1) 
    { 
     @Html.DisplayNameFor(m => m.Price) 
     @Html.TextBoxFor(m => m.Price) € 
     @Html.ValidationMessageFor(m => m.Price) 
    } 
    else 
    { 
     @Html.DisplayNameFor(m => m.MaxPrice) 
     @Html.TextBoxFor(m => m.MaxPrice) € 
     @Html.ValidationMessageFor(m => m.MaxPrice) 
    } 
</div>
