最近我为我的 MVC 4 应用程序更新了几个引用的程序集,并升级到 MVC 5.1。不确定这是否与此有关。
模型
[Display(Name = "Start")]
[DisplayFormat(DataFormatString = "{0t}")]
public System.DateTime StartDateTime { get; set; }
现在我在一个简单的 razor html 助手上遇到了一个奇怪的错误
@Html.DisplayFor(model => model.StartDateTime)
给出错误:输入的字符串格式不正确
。
如果您在调试器中查看该字段的值,它是 System.DateTime 类型并显示:2/28/2014 10:17 AM
更改为 @Html.EditorFor
可以正确呈现数据时间。
我的 DisplayTemplates 文件夹是空的。

最佳答案
尝试指定 DisplayFormat 属性,例如(在您的模型属性上):
[DisplayFormat(DataFormatString = "{0:C}")]
public DateTime StartDateTime { get; set; }
根据已编辑的问题进行编辑:
您的显示格式语法不正确 - 它缺少一个冒号。这样做(注意 0
和 t
之间的冒号):
[Display(Name = "Start")]
[DisplayFormat(DataFormatString = "{0:t}")]
public System.DateTime StartDateTime { get; set; }
关于c# - DateTime 的 Razor DisplayFor = 输入字符串的格式不正确,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/22100726/
