字典与对象作为值 [英] Dictionary with object as value

问题描述

我在这里坚持下去这可能是因为我错过了一些规则，但如果是这样，那么请告诉我。

我正在尝试创建一个 code>一个字符串为key，一个匿名对象为值。或者，实际上我不只是在尝试，我在做。
但是当我想改变对象中的一个特定参数时，它会出错。

我声明这样的字典：

  var areas = new Dictionary< string，object> 
 {
 {Key1，new {name =Name1，today = 0，all = 0}}，
 {Key2，new {name =Name2 = 0，all = 0}}，
 ... 
} 
  

然后我假设我可以这样做：

  foreach（region中的var area.Keys.ToArray（））
 {
 var areaname = areas [area] .name; 
} 
  

但Visual Studio不同意，拒绝编译。如果我写这个，那么一切都按照我的想法工作 - 但是这并不能帮助我，只是让我更沮丧。

  var areaname = new 
 {
 name =Nametest，today = 0，all = 0 
}; 
 var testname = areaname.name; 
  

我做错了什么？为什么不为我工作？这是不可能的吗？

感谢所有的答案，他们肯定清除了一些东西！
我想我可能会混淆类型对象与对象的想法，即C＃中的类，沮丧。我会重新考虑整个设计业务，可能会做一些完全不同的工作，而不是使用恶劣的解决方案。虽然有趣，但我不认为我与C＃的关系已经发展得如此之远！

解决方案

工作是因为你已经将字典声明为 Dictionary< string，object> 。

你可以试试字典< string，dynamic> 。

I'm going nuts here. It's probably because I've missed some rule, but if so, then please tell me.

I'm trying to create a Dictionary with a string for key and an anonymous object as value. Or, actually I'm not just trying, I'm doing it. But when I want to alter a specific parameter in the object, it goes wrong.

I declare the dictionary like this:

var areas = new Dictionary<string, object>
{
  {"Key1", new {name = "Name1", today = 0, all = 0}},
  {"Key2", new {name = "Name2", today = 0, all = 0}},
    ...
}

And then I'm assuming I can do this:

foreach (var area in areas.Keys.ToArray())
{
    var areaname = areas[area].name;
}

but Visual Studio does not agree, and refuses to compile. If I write this, though, everything works as I would think - but that doesn't really help me out, it's just making me more frustrated.

var areaname = new 
            {
                 name = "Nametest", today = 0, all = 0
            };
var testname = areaname.name;

What am I doing wrong? Why isn't it working for me? Is it simply impossible to do so?

Thanks for all your answers, they surely cleared things up a bit! I think I might have been confusing the type object with the idea of objects, that is classes, in C# out of frustration. I'll rethink the whole design business and probably do something completely different instead of using evil or dirty solutions. Though interesting, I don't think my relationship with C# has evolved that far yet!

解决方案

This will not work because you have declared the dictionary as Dictionary<string, object>.

You could instead try Dictionary<string, dynamic>.
