Question

Simple example of scenario I am trying to implement

class ATest
{
    int a;
    int b;
    BTest[];
}

class BTest
{
    int X;
    int Y;
}

• I need to create ATest and BTest dynamically based on a value.
• I tried it as Atest[] aobj = new Atest[count]; (This count value will be set programmatically)
• Now I need to create Array of Objects of B dynamically and assign it to A

• Currently I assume static value for count and assigned it

  Atest[] aobj = new Atest[20];   
  BTest[] bobj = new BTest[1];
  bobj[0] = new Btest();
  aobj[0] = new ATest();
  aobj[0].BTest = bobj;
  BTest[] bobj1 = new BTest[1];
  bobj1[0] = new Btest();
  aobj1[0].BTest = bobj1;
  

This may not be the best way to code.

Please suggest on dynamically implementing it
– Dynamically create number of BTest object arrays and assign it for ATest instances

Answer 1

Try using constructors:

class ATest {
    int a;
    int b;
    BTest[] btests;
    public ATest(int numOfB) {
        btests = new BTest[numOfB];
    }
}

The you can create and initialize your atests in a simple loop:

int M = 20; // Number of Test A objects
int N = 10; // Number of Test B objects per Test A
var atests = new ATest[M];
for (var i = 0 ; i != M ; i++) {
    atests[i] = new ATest(N);
}
