 1 dim s as string = "name:ok,link:none,name:ok2,link:none2"
 2         '提取字符串中"name:"到","之间的字符
 3         dim sp() as string = dsapi.字串提取.提取所有中间文本(s, "name:", ",")
 4         for each m as string in sp
 5             console.writeline(m)
 6         next
 7         '输出 ok ok2

 9 
10         '提取字符串中"link:"到","之间的字符,由于后面的link后面没有","，所以提取的时候后面补一下，使得最后一个link也能被捕捉进来
11         sp = dsapi.字串提取.提取所有中间文本(s & ",", "link:", ",")
12         for each m as string in sp
13             console.writeline(m)
14         next
15         '输出 none none2

18         '提取字符串中的"name:"到","，但只提取第一个匹配的。
19         console.writeline(dsapi.字串提取.提取中间文本(s, "name:", ","))
