ASP.NET MVC data annotation for currency format
提问by immirza
I have following POCO with Cost as float.
我关注 POCO，成本为浮动。
public class CostChart
{
public string itemType { get; set; }
public float? Cost{ get; set; }
}
I need to return Cost in currency format e.g.
我需要以货币格式返回成本，例如
$U 4.882,50.
4.882,50 美元。
What data annotation should I use?
我应该使用什么数据注释？
This is how I am displaying in my view.
这就是我在我看来的显示方式。
<td>@Model.Cost</td>

Have you tried using DataType.Currency:
您是否尝试过使用DataType.Currency：
public class CostChart
{
public string itemType { get; set; }
[DataType(DataType.Currency)]
public float? Cost{ get; set; }
}
Alternatively, you could use DataFormatStringlike this:
或者，您可以DataFormatString像这样使用：
[DisplayFormat(DataFormatString = "{0:C0}")]`
public float? Cost{ get; set; }
But I prefer to set the display format with EditorFor. Here's a great tutorial on Extending Editor Templates for ASP.NET MVCtutorial.
但我更喜欢用EditorFor. 这是一个关于为 ASP.NET MVC教程扩展编辑器模板的很棒的教程。
That way, you write the display logic of your currencies in just ONE place, and you don't need to add that extract annotation every single time you want to display a currency amount.
这样，您只需在一处编写货币的显示逻辑，而无需在每次要显示货币金额时都添加提取注释。

To make it work in EditorFor, you can also add ApplyFormatInEditMode = trueto the end of the DataFormatStringmaking the line as:
要使其在 EditorFor 中工作，您还可以添加ApplyFormatInEditMode = true到DataFormatString制作行的末尾：
[DisplayFormat(DataFormatString = "{0:C0}", ApplyFormatInEditMode = true)]

try this :
尝试这个 ：
public class CostChart
{
public string itemType { get; set; }
[DataType(DataType.Currency)]
public float? Cost{ get; set; }
}
if you still do not see $ symbol, in web.config under write this line of code
如果还是没有看到$符号，在web.config下写这行代码
<globalization culture ="en-us"/>

Check out this article(Codeculous.) an alternate way to validate and display the respective currency symbols without setting Globalization and just by adding the data annotations DataType(DataType.Currency).
查看这篇文章 ( Codeculous.) 验证和显示相应货币符号的另一种方法，无需设置全球化，只需添加数据注释DataType(DataType.Currency)。

You can do in RazorView
你可以在 RazorView 中做
@string.Format("{0:0,0.00,00}", Model.Cost)
