Inline Definition and Declaration

Question

Ok, im sure im mis-wording the concept but here it is anyways.

I know in CSharp you can do

el.AppendChild(new UISize(file, "TSize") { CX = 95, CY = 20 });

which declares a temporary bucket variable and then assigns the associate property values to the variable. Which then sends it to the XMLElement AppendChild method.

1. What is this design concept called?
2. What is the conversion to VB.Net?

I have tried using my own online utility that does a 90-95% conversion rate from C# <-> VB.Net. It has failed in this instance, and so need a hand-up on what i am looking to do to convert this from C# to VB.Net.

I would really like to not have to do a long-declaration of a variable with assignments, if at all possible.

Answer 1

This is using object initializers in C#. The syntax to do the same is subtly different in VB

var uiSize = new UISize(file, "TSize") { CY = 95, CY = 20 }; // C#
Dim uiSize = New UISize(file, "TSize") With {.CX = 95, .CY = 20} ' VB

And, of course, you can inline the instantiation of the object inside a method call as well.

someObject.SomeMethod(New UISize(file, "TSize") With {.CX = 95, .CY = 20})
