人您好我有以下的前preSS验证

Hi people I have the following express validation

    [Required]
    [RegularExpression("{0:d/M/yyyy HH:mm:ss}" , 
    ErrorMessage = "Wrong Syntax")]
    public string Posted { get; set; }` 

但是它不允许以下输入其中正在显示日期和时间的一个例子：
12/12/2011 00:00:00（我不希望这些确切的数字的日期和时间，应该允许它按日期和时间标准逻辑允许任何数字）

But it does not allow the following input which am showing as a example of date and time: 12/12/2011 00:00:00 (I do not want these exact numbers the date and time should allow any numbers which is allowed logically by date and time standards)

I get the error message "Wrong Syntax" even when i input the correct code. What seems to be the problem. Any help will be really appreciated Thank You So Much

推荐答案

这是因为 RegularEx pressionAttribute 需要一个正则表达式模式，您提供一个.NET字符串格式模式（ MSDN：RegularEx pressionAttribute类）。

It is because RegularExpressionAttribute expects a Regex pattern and you are providing a .NET string format pattern (MSDN: RegularExpressionAttribute Class).

对于基本格式验证你需要使用这样的：

For basic format validation you would need to use something like:

[RegularExpression(@"\d{2,2}/\d{2,2}/\d{4,4} \d{2,2}:\d{2,2}:\d{2,2}")]
