<p><span style="font-size: 16px"><strong>Delphi中的转义字符？</strong></span></p>
<p><span style="font-size: 16px">似乎没有。Delphi 中直接用ASCII代替，例如：</span></p>
<p><span style="font-size: 16px">\n&nbsp;-&gt;&nbsp;#10&nbsp; &nbsp; //换行<br>\r&nbsp;-&gt;&nbsp;#13&nbsp; &nbsp; //回车</span></p>
<p><span style="font-size: 16px">如果是对于字符串，有一种情况：</span></p>
<p><span style="font-size: 16px">对&nbsp;<strong> '</strong> 转义，那么需要用两个 <strong>'</strong> 代替。</span><br><span style="font-size: 16px">例如：</span></p>
<div class="cnblogs_Highlighter">
<pre class="brush:delphi;gutter:true;"><span style="font-size: 16px">sStr := 'I can''t do it';   // I can't do it
</span></pre>
</div>
<p><span style="font-size: 16px">　　</span></p>
