取字符串的问题
有一个字符串的内容为：
<img src="abc.jpg" border=0>jadsoiu<img src="bbb.jpg" border=0>adfsafds<img src="ccc.jpg" border=0>deas...
可能有一张或者是几张图片
我想从这个字符串中取出图片，
<img src="abc.jpg" border=0>jadsoiu<img src="bbb.jpg" border=0>adfsafds<img src="ccc.jpg" border=0>deas...

代码可以这样写
Regex r = new Regex(@"[A-Za-z0-9]+\.(jpg|bmp)+", RegexOptions.IgnoreCase); //忽略大小写
string s = " <img src="abc.jpg" border=0>jadsoiu<img src="bbb.jpg" border=0>adfsafds<img src="ccc.jpg" border=0>deas...";
MatchCollection mc = r.Matches(s); //找到所有符合规则的match
foreach(Match m in mc)
{
...
}
Regex r = new Regex(@"[A-Za-z0-9]+\.(jpg|bmp)+", RegexOptions.IgnoreCase); //忽略大小写
string s = " <img src="abc.jpg" border=0>jadsoiu<img src="bbb.jpg" border=0>adfsafds<img src="ccc.jpg" border=0>deas...";
MatchCollection mc = r.Matches(s); //找到所有符合规则的match
foreach(Match m in mc)
{
...
}

string str = " <img src=\"abc.jpg\" border=0>jadsoiu<img src=\"bbb.jpg\" border=0>adfsafds<img src=\"ccc.jpg\" border=0>deas...";
string imgsrc="img src=\"";
int index = str.IndexOf(imgsrc, 0);
while (index > 0)
{
index += +imgsrc.Length;
string img = str.Substring(index, str.IndexOf("\"", index)-index);
Console.WriteLine(img);
index = str.IndexOf("img src=\"", index);
}
string imgsrc="img src=\"";
int index = str.IndexOf(imgsrc, 0);
while (index > 0)
{
index += +imgsrc.Length;
string img = str.Substring(index, str.IndexOf("\"", index)-index);
Console.WriteLine(img);
index = str.IndexOf("img src=\"", index);
}

我的测试代码，存数组就简单了，楼主自己存下吧
string yourStr = ...........;
MatchCollection mc = Regex.Matches(yourStr, @"<img\s+src=""(?<img>[^""]*?)""[^>]*?>", RegexOptions.IgnoreCase);
foreach (Match m in mc)
{
richTextBox2.Text += m.Groups["img"].Value + "\n";
}
string yourStr = ...........;
MatchCollection mc = Regex.Matches(yourStr, @"<img\s+src=""(?<img>[^""]*?)""[^>]*?>", RegexOptions.IgnoreCase);
foreach (Match m in mc)
{
richTextBox2.Text += m.Groups["img"].Value + "\n";
}

用正则
[A-Za-z0-9]+\.(jpg|bmp)+
[A-Za-z0-9]+\.(jpg|bmp)+

正则:
(<img[^>]*?>[^<]*?)+?
(<img[^>]*?>[^<]*?)+?

最好能不能把图片的路径放到一个数组里去

如何匹配
<img align="absmi" border="0" src="aie39c9k/as9/837jd78hj33.gif" width="258" height=""58">
------------------------------------------
string yourStr = ...........;
MatchCollection mc = Regex.Matches(yourStr, @"<img\s+[^>]*?src=""(?<img>[^""]*?)""[^>]*?>", RegexOptions.IgnoreCase);
foreach (Match m in mc)
{
richTextBox2.Text += m.Groups["img"].Value + "\n";
}
