如何从字符串c＃中的锚标记中提取文本

Question

我有一个字符串：

"<a href="/departments/Attachments/2043_3162016062557_test1_Health%20Check‌​%20Assessment.docx">SharePoint_Health Check Assessment.docx</a><br><a href="/departments/Attachments/2043_3162016062557_Test2%20W.docx">Tes‌​t2.docx</a><br>"

我如何修剪它才能得到文字：

/departments/Attachments/2043_3162016062557_test1_Health%20Check‌​%20Assessment.docx

/departments/Attachments/2043_3162016062557_Test2%20W.docx

我只需要网址的文字。

Answer 1

使用RegEx

Regex.Matches("yousStringHere" ,@"(?<=href=\")[^>]+(?=\">)")

Demo

Answer 2

string s = "<a href="/departments/Attachments/2043_3162016062557_test1_Health%20Check‌​%20Assessment.docx">SharePoint_Health Check Assessment.docx</a>"

int start = s.IndexOf("href=") + 5;
int end = s.IndexOf("/"", start);

string result = s.SubString(start, end - start);

没有HTML解析库或使用IndexOf和Substring的RegEx是最简单的方法。 注意：未经测试，使用iPhone编写。
