BitArray无法正常工作

Question

I have this BitArray :

    BitArray bits = new BitArray(2);
    bits[0] = false;
    bits[1] = true;

Which represents : 10b --> 2

Let's see what's its value :

  int[] array = new int[1];
  bits.CopyTo(array, 0);
  Console.WriteLine(array[0]);  // value=2

Great.

Now I'm changing the first code to :

   bool[] bits = new bool[2] {  false, true }; //same value !
   BitArray myBA4 = new BitArray( bits );

   //and again...
   int[] array = new int[1];
   bits.CopyTo(array, 0);
   Console.WriteLine(array[0]);

• Exception : Destination array was not long enough. Check destIndex and length, and the array's lower bounds.

Question

Where is my mistake ? I think it should be same result.

Answer 1

bool[] bits = new bool[2] { false, true };

allocates an array of two elements, and CopyTo is supposed to copy them one by one. It cannot succeed because

• the second array is too short;
• bool cannot be converted to int implicitly.
