I'm using MVC3 with a detailed view that needs to display a formatted dollar amounts like $1,200.00. The controller is passing in a double value in this case for MonthlyMortgage to the view. The line of code below however, does not display the correct string formatting. What is displayed is $1200.00, and what I need is $1,200.00.

我正在使用带有详细视图的MVC3，需要显示格式化的美元金额，如$ 1,200.00。在这种情况下，控制器将MonthlyMortgage传递给视图。但是，下面的代码行不会显示正确的字符串格式。显示的是$ 1200.00，我需要的是$ 1,200.00。

I have tried:

我努力了：

[email protected]("{0:c}", Html.DisplayFor(model => model.MonthlyMortgage))

and I have tried this:

我试过这个：

[email protected]("{0:#,###,###,##0.000}", Html.DisplayFor(model => model.MonthlyMortgage))

Can someone please enplane why this is not working?

有人可以告诉我为什么这不起作用？

2 个解决方案

#1

You don't need to use Html.DisplayFor because it will return MvcHtmlString so the string.Format doesn't apply.

您不需要使用Html.DisplayFor，因为它将返回MvcHtmlString，因此string.Format不适用。

Just use the string.Format on your model:

只需在模型上使用string.Format：

@String.Format("{0:c}", Model.MonthlyMortgage)

Note you don't need the '$' sign anymore because the {0:c} will take care of it.

请注意，您不再需要“$”符号，因为{0：c}会处理它。

@nemesv has a direct answer. The other option would be to remove String.Format() from the View and use DataAnnotations to attach a formatting to MonthlyMortgage.

@nemesv有一个直接的答案。另一种选择是从View中删除String.Format（）并使用DataAnnotations将格式附加到MonthlyMortgage。

An example from MSDN:

来自MSDN的一个例子：

[DisplayFormat(DataFormatString = "{0:C}")]
public Decimal ListPrice { get; set; }

And btw, #,###,###,##0.000 can be shortened to #,##0.00

btw，＃，###，###，## 0.000可缩短为＃，## 0.00

,200.00. The controller is passing in a double value in this case for MonthlyMortgage to the view. The line of code below however, does not display the correct string formatting. What is displayed is 00.00, and what I need is
