从对象类型获取匿名类型

Question

For the code shown below

using System;

public class Test
{
    public static void Main()
    {
        Test t = new Test();
        object AnonymousInside= t.GetAnonymousType();
        Console.Write(AnonymousInside.Key);//Error on compilation
    }

    public object GetAnonymousType()
    {
        return new {Key="KeyName",Value="ValueName"};
    }
}

How can I take the anonymous type back from type object ?

If that is not possible then how this code works?

@Html.TextBoxFor(model => model.ConfirmPassword, new { maxlength = 35, type = "password", @class="textArea  margindrop",placeholder="Confirm password"})

Its Documentation

Answer 1

You can make it dynamic

dynamic AnonymousInside= t.GetAnonymousType();

Though you should use a class,struct instead

---

If you still want to use anonymous type

It's mentioned in the docs :

The compiler provides a name for each anonymous type, although your application cannot access it.

So,the only way to access it through object would be using reflection or dynamic

Answer 2

If you do not want to use dynamic you may try something like this

using System;

public class Test
{
    public static void Main()
    {
        var AnonymousInside = GetAnonymousTyped(GetAnonymousObject(), new {Key="",Value=""});
        Console.Write(AnonymousInside.Key);//All Ok
    }

    public static T GetAnonymousTyped<T>(object o, T _)
    {
        return (T)o;
    }

    public static object GetAnonymousObject()
    {
         return new {Key="KeyName",Value="ValueName"};
    }
}
