asp.net mvc 3 return json array
提问by user603007
Trying to generate an array on the client side for js:
尝试在客户端为 js 生成一个数组：
var ds = [{ text: "john", value: "1" }, { text: "paul", value: "2" }];
In my asp.net mvc 3 controller I have created a entityframework model and trying to return a list :
在我的 asp.net mvc 3 控制器中，我创建了一个实体框架模型并尝试返回一个列表：
NORTHWNDEntities db = new NORTHWNDEntities();
public ActionResult GetCustomers()
{
return Json( db.Customers,JsonRequestBehavior.AllowGet);
}
at the moment I cant figure out just to return the customername+customerid property as a list of customers (NWind database)?
目前我无法弄清楚只是将 customername+customerid 属性作为客户列表返回（NWind 数据库）？

Try this - for each customer create a new anonymous object with the properties you want.
试试这个 - 为每个客户创建一个具有您想要的属性的新匿名对象。
public ActionResult GetCustomers()
{
var customers = from o in db.Customers
select new { customerName = o.CustomerName, customerId = o.CustomerId};
return Json(customers.ToList(), JsonRequestBehavior.AllowGet);
}
Note if you want for ex. "text" and "value" to be the values in your JSON array simply change customerName and customerId above to whatever names you want.
请注意，如果您想要为前。"text" 和 "value" 作为 JSON 数组中的值，只需将上面的 customerName 和 customerId 更改为您想要的任何名称。

var customers = for c in db.Customers
select new { text = c.CustomerName, value = c.CustomerId};
