[英]Using ASP.Net MVC Data Annotation outside of MVC
i was wondering if there is a way to use ASP.Net's Data annotation without the MVC site.我想知道是否有一种方法可以在没有 MVC 站点的情况下使用 ASP.Net 的数据注释。
My example is that i have a class that once created needs to be validated, or will throw an error.我的例子是我有一个类,一旦创建就需要验证,否则会抛出错误。 I like the data annotations method, instead of a bunch of if blocks fired by the initaliser.
我喜欢数据注释方法,而不是初始化程序触发的一堆 if 块。
Is there a way to get this to work?有没有办法让它发挥作用?
I thought it would be something like:我认为它会是这样的:
any ideas?有任何想法吗? i must admit i havent added the MVC framework to my project as i was hoping i could just use the data annotations class System.ComponentModel.DataValidation
我必须承认我还没有将 MVC 框架添加到我的项目中,因为我希望我可以只使用数据注释类 System.ComponentModel.DataValidation
Here's an example:下面是一个例子:
using System;
using System.Collections.Generic;
using System.ComponentModel.DataAnnotations;
public class Foo
{
[Required(ErrorMessage = "the Bar is absolutely required :-)")]
public string Bar { get; set; }
}
class Program
{
public static void Main()
{
var foo = new Foo();
var results = new List<ValidationResult>();
var context = new ValidationContext(foo, null, null);
if (!Validator.TryValidateObject(foo, context, results))
{
foreach (var error in results)
{
Console.WriteLine(error.ErrorMessage);
}
}
}
}
But quite honestly FluentValidation is much more powerful.但老实说, FluentValidation 的功能要强大得多。
