Im trying to modify a C code into C# and Im stuck here:
typedef struct { char index; char f; char g; char k; } todo;
 
static const todo for4[] = {
  {0,2,15,4} , {0,3,5,1} , {0,3,25,11} , {0,5,9,3}

It looks like a delegate function of sort but Im not sure how I could translate the code into C#. I have read this:
http://msdn.microsoft.com/en-us/library/05w82thz%28v=vs.71%29.aspx[^]
 
But still cant wrap my head around how to do it in C#.
 

BTW: There are several simular tables with other eaqualy sized arrays named:
static const todo for6[] = {...
static const todo for12[] = {...

This code should get you going in the right direction :
 
public class todo
    {
        public char index;
        public char f;
        public char g;
        public char k;
    }
 
    public class A{
        static readonly todo[] for4 = 
          new todo[]{new todo(){index='a',f='a',g='a',k='a'},
                                                 
                     new todo(){index = (char)1,f='a',g='a',k='a'}
        };
    }
 
Some shortcuts are possible by providing a constructor to the todo class so that you don't have to name each member in its construction as it is in my example.
I provided one element as (char)1 to show how to use numbers like in your code.

Almost there I guess, so typdef works in this case like a delegate to a List?
Philip Stuyck - 15 Sep '12 - 16:42
A c# delegate to me is a pointer to a method. A typedef in C or C++ is just something for the compiler it does not introduce any code nor does it introduce a new type. In C they usually do typedef struct blabla name; I don't like this syntax, and usually do struct name{blabla}. It is the struct keyword that introduces the new type not the typedef.
