在aspnet 5中找不到JsonRequestBehavior
我正在尝试实现远程验证演示,似乎Microsoft.AspNet.Mvc不包含JsonRequestBehavior枚举.
但它确实存在于以前版本的MVC中的System.Web.Mvc命名空间中
模型:
public class Person : Entity
{
[Required]
[StringLength(512)]
[Remote("IsAllowedName",
"Validation",
ErrorMessage="This name is not allowed!"
)]
[Display(Name = "First (and middle) name")]
public String FirstMidName { get; set; }
视图:
...
<input asp-for="FirstMidName"/>
<span asp-validation-for="FirstMidName"></span>
...
控制器:
[HttpGet]
public JsonResult IsAllowedName(string FirstMidName)
{
if (FirstMidName.ToLower() == "oleg")
{
return Json(false, JsonRequestBehavior.AllowGet);
}
return Json(true);
}
终端输出:
MacBook-Air-Anton:labefmvc antonprudkoglyad$dnu build
...
/Users/antonprudkoglyad/Projects/LabEFMVC/LabEFMVC/Controllers/
ValidationController.cs(20,24):
DNXCore,Version=v5.0 error CS0103: The name 'JsonRequestBehavior'
does not exist in the current context
Build failed.
最佳答案 在ASP.NET Core RC1中,[Remote]属性位于Microsoft.AspNet.Mvc命名空间中.
在ASP.NET Core RC2中,我相信[Remote]属性位于Microsoft.AspNetCore.Mvc命名空间中.
using Microsoft.AspNet.Mvc;
[Remote("IsAllowedName", "Validation", ErrorMessage="This name is not allowed!" )]
