C# regular parsing HTML to capture all images_html/css_WEB-ITnose
抓取html中的所有图片，目前img标签中的已经能够拿出来了，但是还有一些是这样写的
比如
<div style="background-image:url('../image/493aid.png')"></div><div style="background-image:url(../image/493aid.png)"></div>或者是这种写法
<div style="background:url('../image/493aid.png')"></div>也有可能不是div，可能是td，或者其他标签。
弄了半天，始终没弄好。
求大神帮助。

有的图片是流输出的 也是要考虑的
<body ><div id = "a"><div style="background-image:url('../image/493aid.png')"></div><div style="background-image:url(../image/491aid.png)"></div><div style="background:url('../image/492aid.png')"></div></div></body><script>var all = document.getElementById("a").innerHTML, reg = /[^\'\"\(]+(\.png|\.jpf|\.bmp)/g;console.log(all);allImg = all.match(reg);console.log(allImg);var allimg = [];all.replace(reg,function($1){ allimg.push($1);});console.log(allimg);说起来，感觉你去抓取这些没有意义的啊，大部分的背景图片，都是以class中加载过来的。
一般不写在标签中的啊。

虽然你完全没达到我的要求，但是还是给分，我已经自己实现，一边看正则表达式的基础，一遍写正则验证，已经搞定了我的这个需求，虽然不是那么完美。

The difference between multithreading and asynchronous c#
Apr 03, 2025 pm 02:57 PM
The difference between multithreading and asynchronous is that multithreading executes multiple threads at the same time, while asynchronously performs operations without blocking the current thread. Multithreading is used for compute-intensive tasks, while asynchronously is used for user interaction. The advantage of multi-threading is to improve computing performance, while the advantage of asynchronous is to not block UI threads. Choosing multithreading or asynchronous depends on the nature of the task: Computation-intensive tasks use multithreading, tasks that interact with external resources and need to keep UI responsiveness use asynchronous.
