有没有一种简单的方法来合并C＃匿名对象

问题描述：

比方说，我有两个匿名对象是这样的：

Let's say I have two anonymous objects like this:

var objA = new { test = "test", blah = "blah" };
var objB = new { foo = "foo", bar = "bar" };

我想将它们组合得到：

I want to combine them to get:

new { test = "test", blah = "blah", foo = "foo", bar = "bar" };

我不知道是什么特性都是objA和objB在编译时。
我想这是像jQuery的扩展方法。

I won't know what the properties are for both objA and objB at compile time. I want this to be like jquery's extend method.

有人知道图书馆或.NET Framework类，可以帮助我做到这一点的？

Anybody know of a library or a .net framework class that can help me do this?

答

如果你真的做意味着在C＃4.0的动态感，那么你可以这样做：

If you truly do mean dynamic in the C# 4.0 sense, then you can do something like:

static dynamic Combine(dynamic item1, dynamic item2)
{
    var dictionary1 = (IDictionary<string, object>)item1;
    var dictionary2 = (IDictionary<string, object>)item2;
    var result = new ExpandoObject();
    var d = result as IDictionary<string, object>; //work with the Expando as a Dictionary

    foreach (var pair in dictionary1.Concat(dictionary2))
    {
        d[pair.Key] = pair.Value;
    }

    return result;
}

您甚至可以编写使用反射版本它有两个对象（非动态），并返回一个动态的。

You could even write a version using reflection which takes two objects (not dynamic) and returns a dynamic.
