Odd IndexOutOfRangeException，即使被抓住

本文关键字：IndexOutOfRangeException Odd | 更新日期: 2023-09-27 17:57:24

好吧，我有一个公共静态常量：

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

.

调试向我显示了以下代码（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时，它向我显示 num12 是 0，聊天线是 chatLine[0]。 这很奇怪，因为我的公众常识就像我上面向您展示的那样...... 知道为什么会这样吗？

..

完整堆栈跟踪如下：

Odd IndexOutOfRangeException，即使被抓住

由于chatLine的长度为零，因此创建数组时numChatLines为零。您应该在设置 numChatLines 后创建数组。

这可能是因为numChatLines在之后被赋予了一个值

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

.. 被初始化，这将给出一个 0 值。

尝试：

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