奇数IndexOutOfRangeException，即使被捕获也是如此

问题描述

|| 好吧，我有一个公共静态常量：

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

。 调试向我显示了此代码（稍后在同一文件中）：

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

将鼠标悬停在每个数据点上后，将显示num12为0，chatLine为chatLine [0]。这很奇怪，因为我的公共常量与我在上面显示的一样……知道为什么会这样吗？ 。 。 完整的堆栈跟踪如下：

system.indexOutOfRangeException was unhandled
  Message=Index was outside the bounds of the array.

解决方法

由于

chatLine

的长度为零，因此创建数组时the4ѭ的长度为零。设置

numChatLines

后应创建数组。     ,这可能是因为numChatLines在

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

..被初始化，将给出一个0值。 尝试：

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