c# - C# 正则表达式解析以从 Markdown 中提取照片？

Question

markdown 中的照片看起来像![alt text](src). 我想解析一个降价块，将所有照片源拉到一个IList<string>.

我知道正则表达式可能是答案，但它对我来说就像一种古老的神秘语言......我将如何将所有照片解析成IList<string>使用 C#？

When I say "Japanese-Chinese" food I'm not referring to some new type of restaurant      serving both Japanese and Chinese food. This means the restaurant serves Chinese food   prepared for Japanese tastes.

This is **subuta** -- sweet and sour pork, this one photo showing the meal set (tenshoku in Japanese). It's one of many Chinese dishes this restaurant serves... and they have **A LOT**!

Answer 1

像这样的东西，应该工作：

!\[.*?\]\(.*?\)

在这里玩一下，看看它是如何工作的：

var matches = new Regex(@"!\[.*?\]\(.*?\)")
    .Matches(str)
    .Cast<Match>()
    .Select(m => m.Value)
    .ToList();
