如何按章节编号对列表进行编号？

我想在我的文档中包含多个带有章节的列表。我还希望每个列表都有标签，例如清单 2.1其中 2 是部分编号，1 是该部分中给定列表的编号。到目前为止，我能够生成以下代码：

\documentclass[a4paper]{article}
\usepackage{listings}
\lstset{frame=Trbl,numbers=left}

\begin{document}
\renewcommand{\thelstlisting}{\thesection.\arabic{lstlisting}}

\section{Introduction}
First listing is numbered properly.
\begin{lstlisting}[caption=First listing]
Lorem
Ipsum
\end{lstlisting}
Second is correct too.
\begin{lstlisting}[caption=Second listing]
Dolor sit Amet
\end{lstlisting}
So far, all listings in one section are correct.
\section{First problem}
When a new section begins, the counter doesn't get reset.
\begin{lstlisting}[caption=First listing in second section]
consectetur
adispicing
elit
\end{lstlisting}
\end{document}

但这会产生以下结果： 产生的结果

如何在每个部分开始后重置计数器？

解决方案是包含包chngcntr并放置\counterwithin{lstlisting}{section}在后面\begin{document}。完整的代码如下

\documentclass[a4paper]{article}
\usepackage{listings,chngcntr}
\lstset{frame=Trbl,numbers=left}
\usepackage{amsmath}

\begin{document}
\counterwithin{lstlisting}{section}

\section{Introduction}
First listing is numbered properly.
\begin{lstlisting}[caption=First listing]
Lorem
Ipsum
\end{lstlisting}
Second is correct too.
\begin{lstlisting}[caption=Second listing]
Dolor sit Amet
\end{lstlisting}
So far, all listings in one section are correct.
\section{First problem}
When a new section begins, the counter doesn't get reset.
\begin{lstlisting}[caption=First listing in second section]
consectetur
adispicing
elit
\end{lstlisting}
\end{document}
