An anonymous type (vb.net)

Objects can be initialized as an anonymous type without even creating or naming a class.

Dim myObject = New With { .id = 1, .type="dog", .name="hello" }

The compile will create and initialize a type for you.

With the "Key" keyword, it will allow you to select exactly which variables in an anonymous type should be used in either the calculation of a hashcode (using GetHashCode) or an equality comparison.


Dim myObject = New With {Key .id = 1, Key .type="dog", Key .name="hello" }

Dim myObject2 = New With {Key .id = 1, Key .type="dog", Key .name="hello" }

Console.WriteLine(myObject.GetHashCode)

Console.WriteLine(myObject .Equals(myObject2 ))
