Question

在我看来,我有一个模式,我想以具体的方式加以编排。

[DisplayFormat(DataFormatString = "{### ##}")] 
 [Display(Name = "Postnr")] 
 public string CustomerZip;

认为:

@Html.DisplayFor(modelItem => item.CustomerZip)

在亚洲开发银行,这些数值被储存为第##号,因此,我在尝试这一方法时发现了一个错误:“以正确的格式显示数据”。我认为(或相当希望)数据表会为我调整方向。

赞赏就如何以最佳方式做到这一点提出的任何建议。

Answer 1

几个方面:

The DataFormatString needs to use the {0:...} indexer style format string, like you d use in string.Format. So you d need to do something like [DisplayFormat(DataFormatString="{0:### ##}"]. If the braces are supposed to be literal, then you d use [DisplayFormat(DataFormatString="{{{0:### ##}}}")]. However...
There is no such format character # for strings. That is what you d use for a numeric type. If you are storing the value as an integer, then you re in luck; just change the type of CustomerZip to int.
If you are NOT storing the value as an integer, but as a string (as you are wont to do with postal codes, usually), then you ve got more of a problem. Like I said, you don t have any custom format options with strings. You d need to represent CustomerZip as some custom type that is IFormattable, which you would define.

Answer 2

采用以下格式:

<代码>{0:###}>

Answer 3

• 采用“Raw”这样的功能:

@Html.Raw(项目.Valor.ToString(“##”)

它用于任何类型的数据。
