What is the Difference Between `new object()` and `new {}` in C#?

Question

First of all i searched on this and i found the following links on Stack Overflow:

• Is there any difference between `new object()` and `new {}` in c#?
• Difference between object a = new Dog() vs Dog a = new Dog()

But i'm not satisfied with this answer, it's not explained well (i didn't get it well). Basically, i want to know the difference between new object() and new {}. How, they are treated at compile time and runtime?

Secondaly, i have the following code which i have used for WebMethods in my asp.net simple application

[WebMethod] [ScriptMethod(UseHttpGet = false)] public static object SaveMenus(MenuManager proParams) {     object data = new { }; // here im creating an instance of an 'object' and i have typed it `new {}` but not `new object(){}`.     try     {         MenuManager menu = new MenuManager();             menu.Name = proParams.Name;         menu.Icon = proParams.Icon;         bool status = menu.MenuSave(menu);         if (status)         {             // however, here i'm returning an anonymous type             data = new             {                 status = true,                 message = "Successfully Done!"             };         }     }     catch (Exception ex)     {         data = new { status = false, message = ex.Message.ToString() };     }     return data; } 

So, (as you can see in comments in code), How new object(){} and new {} differences?

Is this even the right way that i have write the code? Can you suggest a best way for this code?

I know, i can't explain it well and i'm asking alot, but that's the best i have right now.

Answer 1

new {...} always creates an anonymous object, for instance:

  Object sample = new {};   String sampleName = sample.GetType().Name; // <- something like "<>f__AnonymousType0"                                               //                    not "Object" 

while new Object() creates an instance of Object class

  Object sample = new Object() {};   String sampleName = sample.GetType().Name; // <- "Object" 

since all objects (including anonymous ones) are derived from Object you can always type

  Object sample = new {};
