string.Format不使用纯方法的返回值

I am using razor to display decimals from my view model and then trying to format the decimals into currency:

我正在使用剃刀从我的视图模型中显示小数,然后尝试将小数格式化为货币:

@if (Model != null && Model.Order != null)
{
    foreach (var item in Model.Order.Where(x => x.OrderInStep2 != null))
    {
      String.Format("{0:C}", item.OrderInStep2)
    }
}

I am getting an Return value of pure method is not used warning, but I thought it should still work. However, the formatted item is not displaying at all. It does display when I take away the formatting though. Am I missing something here? Thanks!

我得到的纯值方法的返回值没有使用警告,但我认为它应该仍然有用。但是,格式化的项目根本不显示。当我拿走格式时它会显示。我在这里错过了什么吗?谢谢!

#1

You need to render the value in a code block like this:

您需要在代码块中呈现值,如下所示:

@if (Model != null && Model.Order != null)
{
    foreach (var item in Model.Order.Where(x => x.OrderInStep2 != null))
    {
      <text>@String.Format("{0:C}", item.OrderInStep2)</text>
    }
}

#2

You just run the code, and do nothing with the result.

您只需运行代码,并对结果不执行任何操作。

Put the result within text tag:

将结果放在文本标记中:

<text>String.Format("{0:C}", item.OrderInStep2)</text>
