Hello
i have 2 forms ,form1 has classe inside class ,i generate public static array of those classes in form1.
static public father[] xx = new father[3];//<----see line A in the code below
In form2 i wrote
int saveIn;
saveIn = Form1.xx[0].P[0].V[0].X;
the progrm did not run the error is
Inconsistent accessibility: field type 'test.Form1.father[]' is less accessible than field 'test.Form1.xx'

how could i redefine the above classes in order to have the program run ?
many thanks

What I have tried:

//Classes are in form1
    class MyNum
    {
        private int x;
        public MyNum() { }
        public MyNum(int Xx) { X = Xx; }
        public int X { get { return x; } set { x = value; } }
    }//MyNum
    class Sun
    {
        public int n;
        public MyNum[] V;
        public Sun() { }
        public Sun(int Xn) { N = Xn; }
        public int N { get { return n; } set { n = value; } }
        public MyNum this[int i]
        { get { return V[i]; } set { V[i] = value; } }
    }//MyLine
    class father
    {
        public int x;
        public Sun[] P;
        public father() { }
        public father(int Xx) { X = Xx; }
        public int X { get { return x; } set { x = value; } }
        public Sun this[int i] { get { return P[i]; } set { P[i] = value; } }
    }//father
    static public father[] xx = new father[3];//<--------------Line A
    // the line below is in Form_2_Load
         int SaveInt;
     saveInt = Form1.xx[0].P[0].V[0].X;

Solution 1

C# is case sensitive; these two lines do not refer to the same variable:

int SaveInt;
saveInt = Form1.xx[0].P[0].V[0].X;

Fix that, and it'll compile.
It won't work - you'll get null reference errors because you haven't created any father instances in the array xx - but it'll compile.
You need to something like this as well:

C#

for (int i = 0; i < 3; i++)
   {
   xx[i] = new father();
   }
