Question

C# 怎么用indexof,substring,lastindexof 3个方法来截取字符串里的字符

m = reginfo.Match(art.FullHtml);

if (m.Success)
{
string che = m.Groups[1].Value;
//art.Contact = che.Substring(XXXXXXXXX);
}
else
{
error += "信息未知";
}
我把文章的内容传了进来，想把里面首尾的<p>和</p>去掉怎么用那三个方法。。

Answer 1

art.FullHtml = art.FullHtml.substring(art.FullHtml.indexOf(">")+1,art.FullHtml.lastIndexOf(art.FullHtml)-art.FullHtml.indexOf(">"))

Answer 2

最简单的是che.Replace("<p>","");che.Replace("</p>","");
