使用LINQ，是它可以输出从SELECT语句动态对象？如果是这样，怎么样？ [英] Using LINQ, is it possible to output a dynamic object from a Select statement? If so, how?

问题描述

目前在LINQ，下面的编译和工作得很好：

Presently in LINQ, the following compiles and works just fine:

var listOfFoo = myData.Select(x => new FooModel{
     someProperty = x.prop1,
     someOtherProperty = x.prop2
});

public class FooModel{
     public string someProperty  { get; set; };
     public string someOtherProperty  { get; set; };
}

然而，.NET / C＃在过去的几个版本都扩大的作用动态对象，如 ExpandoObject ，我想知道如果有一种方法可以基本上做到这一点：

However, the past few versions of .NET/C# have expanded the role of dynamic objects such as the ExpandoObject and I am wondering if there is a way to basically do this:

var listOfFoo = myData.Select(x => new ExpandoObject{
     someProperty = x.prop1,
     someOtherProperty = x.prop2
});

显然，我已经尝试过上面的代码没有成功，但似乎我失去了一些东西。

Obviously, I have already tried the code above without success, but it seems like I am missing something.

推荐答案

您应该能够在不宣布任何类型来创建一个新的匿名对象：

You should be able to create a new anonymous object without any type declared:

var listOfFoo = myData.Select(x => new {
    someProperty = x.prop1,
    someOtherProperty = x.prop2
});
