如果我用\cfoot它来评估并打印此部分计数器，它会在我的附录中显示正确的部分编号。
然而，当我使用 评估节计数器时\ifnumequal，它表明平等的表达式是绝不遇到了。为什么？
一个不那么简单的例子：

答案1
这个例子太长了。至少可以分析一下这个问题：
\ifnumequal{\number\value{CurrentSectionCounter}}{2}{%
\cfoot{\number\value{CurrentSectionCounter}}%
}{%
\cfoot{Wrong number}%
}% This line always yields "wrong number"
比较只在执行时进行一次。显然此时\ifnumequal的值不同，因此所有后续页面的页脚均设置为。CurrentSectionCounter\cfoot{Wrong number}
