stringlength 属性错误消息采用哪些参数? [英] What parameters does the stringlength attribute errormessage take?

问题描述

在 MVC4 模板中，使用的数据注释属性之一是 stringlength.

In the MVC4 template one of the data annotation attributes used is stringlength.

例如:

[StringLength(100, ErrorMessage = "The {0} must be at least {2} characters long.", MinimumLength = 6)]

哪些参数 {0}、{1}、{2}(更多?)是合法的?

What parameters {0}, {1}, {2} (more?) are legal?

更具体地说，我可以从示例和反复试验中看到可能性是什么，但我希望看到一些硬文档.

To be more specific, I can see from the example and trial and error what the possibilities are, but I would like to see some hard documentation.

我在 StringLengthAttribute 文档中找不到任何关于此的信息.

I can't find anything about this in the StringLengthAttribute documentation.

推荐答案

{0} 索引是属性的显示名称，{1} 是MaximumLength，{2} 是 MinimumLength.因此，您的错误消息将被格式化为 Foo 的长度必须至少为 6 个字符."

The {0} index is the display name of property, {1} is the MaximumLength, {2} is the MinimumLength. So, your error message will be formate as "The Foo must be at least 6 characters long."
