Question

I’m new to C#, so forgive this noobish question. I’m playing with a simple XNA game demo. I have a struct that I want to be available to several classes. It is defined as follows:

PhotonType.cs

using System;

namespace ShipDemo
{
 public struct PhotonType {
        public Color tint;
 }
}

In another file in the same folder/namespace, Ship.cs, I reference this struct:

namespace ShipDemo {
    public class Ship {
    //...
       private PhotonType photonType;
       //...
       public Ship(float x, float y, float ang, Boolean correctSound, PhotonType photonType) {
    //...
  }
}

This gives me compilation errors on both references to PhotonType.

Error 1 The type or namespace name
‘PhotonType’ could not be found (are
you missing a using directive or an
assembly
reference?)

What am I doing wrong here?

Also, the C# documentation says

It is an error to initialize an
instance field in a struct.

But what if I want to provide default values?

I’m using Visual Studio Ultimate 2010 Beta.

Answer 1

Are the 2 files in the same Project? If your namespace is split up between 2 projects, you need to reference the project containing PhotonType in the other project.

I fthis is the case, I would question the design as usually we don’t split the same namespace in more than one assembly.
