Question

Dysfunctional Example:

public struct MyStruct { public int i, j; }

static readonly MyStruct [] myTable = new MyStruct [3] 
{
    {0, 0}, {1, 1}, {2, 2}
}

I know that this code doesn’t work. Now how do I write this down please (proper syntax)?

The thought behind this is the following. Afaik the elements of arrays of struct are value types, so myTable points to a memory location containing three MyStruct objects (and not to a memory location containing three (uninitialized) pointers to MyStruct objects).

So how do I go about initializing those MyStruct objects, what would be the right syntax? I don’t have to allocate them anymore, right?

Answer 1

You need to use actual instances of your MyStruct, which you can create with the new keyword.

This should work…

struct MyStruct 
{ 
   int i, j; 

   public MyStruct(int a, int b)
   {
      i = a;
      j = b;
   }
}

static MyStruct[] myTable = new MyStruct[3]
{
   new MyStruct(0, 0),
   new MyStruct(1, 1),
   new MyStruct(2, 2)
};
