I would like to ask how can I make below structured data globally available to all classes:

```
class clsData1
{
   int Num1;
   int Num2;
   string Str1;
}

class clsData2
{ 
   int Num3;
   int Num4;
   string Str2;
}

class Main
{
   clsData1 clsData1A;
   clsData2 clsData2A;
}

```

I guess solution is with singleton, but example would be helpful.

Aditionally I would like that this data structure works as global over all classes.
