从字典中的属性C＃匿名对象 [英] C# anonymous object with properties from dictionary

问题描述

我想一个字典转换为匿名类型与一个属性为每个关键。

I'm trying to convert an dictionary to an anonymous type with one property for every Key.

我试图谷歌，但所有我能找到的是如何转换一个匿名对象字典。

I tried google it but all I could find was how to convert a anonymous object to a dictionary.

我的字典看起来是这样的：

My dictionary looks something like this:

var dict = new Dictionary<string, string>
{
    {"Id", "1"},
    {"Title", "My title"},
    {"Description", "Blah blah blah"},
};

，我想返回一个匿名对象，看起来像这样。

And i would like to return a anonymous object that looks like this.

var o = new 
{
    Id = "1",
    Title = "My title",
    Description = "Blah blah blah"
};

所以，我会把它想环通每keyValuePair在字典中，并在对象创建一个属性每一个键。

So I would like it to loop thru every keyValuePair in the dictionary and create a property in the object for every key.

我不知道从哪里开始。

请帮忙。

推荐答案

您不能，基本上是这样。匿名类型是由编译器创建的，所以他们在汇编中存在与烤到他们所有的财产的名称。 （该属性的类型的是在此情况下的一个问题 - 作为一个实现细节，编译器创建的通用型，然后创建的，使用适当类型的参数的实例。）

You can't, basically. Anonymous types are created by the compiler, so they exist in your assembly with all the property names baked into them. (The property types aren't a problem in this case - as an implementation detail, the compiler creates a generic type and then creates an instance of that using appropriate type arguments.)

您正在寻求一种与以的执行的决定性质的时间 - 这只是不具有匿名类型是如何工作的契合。你不得不基本上编译使用它在执行时的代码 - 那么这将是一个痛苦，因为它会在不同的装配和匿名类型是内部...

You're asking for a type with properties which are determined at execution time - which just doesn't fit with how anonymous types work. You'd have to basically compile code using it at execution time - which would then be a pain as it would be in a different assembly, and anonymous types are internal...

也许你应该使用 ExpandoObject 呢？然后，使用动态什么就能访问属性为正常。

Perhaps you should use ExpandoObject instead? Then anything using dynamic will be able to access the properties as normal.
