Odd IndexOutOfRangeException, even when caught

Well, I have a public static const of:

public static ChatLine[] chatLine = new ChatLine[numChatLines];

.

The debug shows me this code (later in the same file):

for (int num12 = 0; num12 < numChatLines; num12++)
{
    chatLine[num12] = new ChatLine();
}

Upon mousing over each data point, it shows me that num12 is 0 and chatLine is chatLine[0]. Which is very odd, since my public const is as I showed you above... Any idea why this is happe开发者_运维百科ning?

. .

The full stack trace is below:

As the length of chatLine is zero, numChatLines is zero when the array is created. You should create the array after setting numChatLines.

This is probably because numChatLines is given a value after

public static ChatLine[] chatLine = new ChatLine[numChatLines];

.. is initialised, which would give a 0 value.

Try:

public static ChatLine[] chatLine;
void main()
{
  /* ... your code ... */
  numChatLines = 12;
  chatLine = new ChatLine[numChatLines];
}
