如何检索JsonResult数据 [英] How to retrieve JsonResult data

问题描述

我的版式控制器中有以下操作

I have the following Action in my layouts Controller

public JsonResult getlayouts(int lid)
{
    List<layouts> L = new List<layouts>();
    L = db.LAYOUTS.Where(d => d.seating_plane_id == lid).ToList()

    return new JsonResult { Data = L, JsonRequestBehavior = JsonRequestBehavior.AllowGet };
}

我正在从另一个控制器调用此动作，如下所示:

I am calling this Action from another controller like so:

layoutsController L = new layoutsController();
JsonResult result = L.getlayouts(lid);

我的问题是:如何从结果对象中获取数据?

My question is: how can I get the data from result object?

推荐答案

好，看看如何构建对象:

Well, have a look how you're building the object:

new JsonResult { Data = L, JsonRequestBehavior = JsonRequestBehavior.AllowGet }

您正在将L变量设置为名为Data的属性.因此，只需阅读该属性即可:

You're setting the L variable to a property called Data. So just read that property:

List<layouts> L = (List<layouts>)result.Data;

这是MVC控制器动作，对此没有什么特别的.

There's nothing special about the fact that it's an MVC controller action.

您只是在调用一个方法，该方法返回在该方法中构造的对象，并从该对象读取属性.就像其他C#代码一样.

You're simply calling a method which returns an object that was constructed in the method, and reading properties from that object. Just like any other C# code.
