c# - 奇数IndexOutOfRangeException，即使被捕获

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：

最佳答案

由于chatLine的长度为零，因此在创建数组时numChatLines为零。设置numChatLines后，您应该创建阵列。
