I am attempting to convert a C++ application to C#.  In the application I 
use a static array of structures to maintain a device capabilities matrix.  
Basically I am communication with a series of devices across the internet.  
All of the devices are these same but have minor differences based on model 
and firmware revision.  To keep it strait, in the C++ app I defined a 
structure containing the variable parameters for a device.  Then I created 
a static array of this stricture which is populated with the appropriate 
parameters for the model.

struct TWidget
{
  int MemAvail;
  int MemOffset;
};

static TWidget Widget[2] =
{
  {0x100,0x200},
  {0x120,0x400}
};

In my app I can just refer to Widget[Model].MemAvail  which will give me 
the amount of available memory for any model.  When we release a new model, 
I just add a new layer to the array...

How can I convert it to C#?  So far I can find no syntax that works.

You could do something like:

    struct TWidget
    {
    int MemAvail;
    int MemOffset;
        internal TWidget(int a, int o) { MemAvail = a; MemOffset = o;
}
    };


    class Program {

        static TWidget[] Widget = {
          new TWidget(1,2),
          new TWidget(2,4)  
         };

Thanks, I will give it a shot, but I wish there were an easier way to 
implement a static data table.

I use this a lot for lookup tables in conversion routines.

What about some sort of constant declaration?

As an alternative I am considering loading the tables from files, or 
possible program resources.
