System.Collections.Generic.IEnumerable'不包含任何定义'了ToList“ [英] System.Collections.Generic.IEnumerable' does not contain any definition for 'ToList'

问题描述

下面是问题所在。我自ViewPage越来越IEnumerable和当我试图转换列表它显示我像错误：

Here is the problem. I am getting IEnumerable from ViewPage and when I tried it to convert List it is showing me error like:

System.Collections.Generic.IEnumerable＆LT; Pax_Detail＆GT; '不包含
  对于'了ToList'，没有扩展方法'了ToList'接受的一个定义
  类型的第一个参数
   System.Collections.Generic.IEnumerable＆LT; Pax_Detail＆GT; '可以找到
  （是否缺少using指令或程序集引用？）

'System.Collections.Generic.IEnumerable<Pax_Detail>' does not contain a definition for 'ToList' and no extension method 'ToList' accepting a first argument of type 'System.Collections.Generic.IEnumerable<Pax_Detail>' could be found (are you missing a using directive or an assembly reference?)

下面是我的控制器code：

Here is my controller code:

[HttpPost]
public ActionResult Edit_Booking(Booking model, IEnumerable<Pax_Detail> pax)
{
  List<Pax_Detail> paxList = new List<Pax_Detail>();
  paxList = pax.ToList(); //getting error here
  BookingDL.Update_Booking(model, paxList);
  return View();
}

我还有一个控制器上应用相同的逻辑。而且这是工作的罚款。我不知道有什么样的问题。我已经清理，改造项目也重新启动我的笔记本电脑（虽然它需要）。

I have applied same logic on another controller. And it is working fine. I don't know what problem it has. I have already clean, rebuild project and also restarted my laptop(though it was needed).

推荐答案

您缺少using指令为 System.Linq的？

Are you missing a using directive for System.Linq?
