c# creating a instance object of something

Question

Hi I was wondering if something like this was possible or not, I'm sure my title question wasn't clear.

Say I have a function that returns a JSON representation of an object. Note: This is more pseudocode than anything don't correct me on the function.

public static json function(object){

}

Is it possible to define an object like this (I'm working with c#)

var exampleObject = { Name: "x" , PhoneNum: "123456789" }

I was hoping there would be a way to create a object with object attributes just like that on the fly without having to make a class like:

class exampleObject{
string name;
string phoneNum;
}

Does something like this exist? Thanks.

What you're asking for breaks the strong statically-typed nature of C#. If you really want to do this, you can de-serialize the JSON into a dynamic object. However, it's much better to use either a Dictionary, or your own strongly-typed class which is much safer. See How to decode a JSON string using C#? — Jonathon Reinhart

You were close. Check out documentation on anonymous types: msdn.microsoft.com/en-us/library/bb397696.aspx — itsme86

Yes. These are called anonymous types (although format and usage is a little different than what you have there). You can find much more about anonymous types in C# on MSDN: http://msdn.microsoft.com/en-us/library/bb397696.aspx.

An example usage using info from your question would be:

var exampleObject = new { Name = "x", PhoneNum = "123456789" };

Take a look at ExpandoObject

dynamic exampleObject = new ExpandoObject();      
exampleObject.Name= "X";
exampleObject.PhoneNum= "123456789";
