我怎么在Linq这样做？

i've got an IList<Foo> and I'm trying to serialize it as Json without the field names included in the result. As such, i'm trying to create an anonymous object, which i pass to the Json serialization method.

我有一个IList ,我试图将其序列化为Json而不包含结果中的字段名称。因此,我正在尝试创建一个匿名对象,我将其传递给Json序列化方法。

Foo is defined as (pseudo code):-

Foo定义为(伪代码): -

public class Foo
{
    public int X;
    public int Y;
}

When i return this as Json ...

当我以Json的身份归还时......

return Json(foos);

the result is like

结果是这样的

... [{"X":1,"Y":2},{"X":3,"Y":4}...]

I don't want the X and Y to be there. So i'm after..

我不希望X和Y在那里。所以我在追求..

... [{1,2},{3,4}...]

So i was trying to do the following (which doesn't work)

所以我试图做以下(这不起作用)

(from p in foos
 select new p.X + "," + p.Y).ToArray()

(from p in foos
 select new string(p.X+ "," + p.Y)).ToArray()

but to no avail (doesn't compile).

但无济于事(不编译)。

Can anyone help, please?

有人可以帮忙吗?

4 个解决方案

#1

(from p in foos
 select String.Format("{{{0}, {1}}}", p.X, p.Y)).ToArray()

#2

foos.Select(p=>p.X + "," + p.Y)

Or if you perfer Linq Syntax:

或者如果你更喜欢Linq语法:

(from p in foos
 select p.X + "," + p.Y).ToArray()

JSON is a member serializer, and uses the names. If you don't want names, don't use JSON. Perhaps just StringBuilder, then?

JSON是成员序列化程序,并使用名称。如果您不想要名称,请不要使用JSON。或许只是StringBuilder,那么?

StringBuilder sb = new StringBuilder("[");
foreach(var foo in items) {
  sb.Append('{').Append(foo.X).Append(',').Append(foo.Y).Append("},");
}
sb[sb.Length - 1] = ']';
string s = sb.ToString();

Why not just create the JSON string yourself, so you have complete control over how it is set up rather than using the Serialization method.

为什么不自己创建JSON字符串,这样您就可以完全控制它的设置方式,而不是使用Serialization方法。

#1

(from p in foos
 select String.Format("{{{0}, {1}}}", p.X, p.Y)).ToArray()

#2

foos.Select(p=>p.X + "," + p.Y)
