Why this declaration is legal

Boki

Hi All,

I saw a code:

vertexBuffer = new VertexBuffer(
typeof(CustomVertex.TransformedColored), 3, dev, 0,
CustomVertex.TransformedColored.Format, Pool.Default);

but why not:

VertexBuffer vertexBuffer = new VertexBuffer(
typeof(CustomVertex.TransformedColored), 3, dev, 0,
CustomVertex.TransformedColored.Format, Pool.Default);

Best regards,
Boki.

Boki,

They should both be legal. What is the compiler error that you are
getting with the second declaration?

Why not indeed ? Both are legal, the first one assumes that there is already
either a field or a local variable of type VertexBuffer called vertexBuffer.
The second line declares the variable and initialises it at the same time.

Hi All,
Sorry, I miss there is a public variable:

/////////////////////////////////////////////////////////////
public class Vertices : Form
{
// Our global variables for this project
Device device = null; // Our rendering device
VertexBuffer vertexBuffer = null;

Best regards,
F.Y.
