怎样从一个字段是切割出所有图片地址保存到数组中

Question

 string ss = "<p><img height='0' width='0' alt='' src='/project/UserFiles/Image/a.jpg' /><img height='115' width='140' alt='' src='/project/UserFiles/Image/cgzs/01.jpg' /></p>" +
"<p><img height='80' width='120' alt='' src='/project/UserFiles/Image/cgzs/03.jpg' /></p>";现在要得到的数组结果如下/project/UserFiles/Image/a.jpg
/project/UserFiles/Image/cgzs/01.jpg
/project/UserFiles/Image/cgzs/03.jpg 

Answer 1

   private void button2_Click(object sender, EventArgs e)
        {
            string ss = " <p> <img height='0' width='0' alt='' src='/project/UserFiles/Image/a.jpg' /> <img height='115' width='140' alt='' src='/project/UserFiles/Image/cgzs/01.jpg' /> </p>" +
" <p> <img height='80' width='120' alt='' src='/project/UserFiles/Image/cgzs/03.jpg' /> </p>";
           MatchCollection mc=  Regex.Matches(ss, @"src=\S*\s*/>");
           List<string> list = new List<string>();
           foreach (Match m in mc)
           {
              
               string s=m.Value.Replace("src='",string.Empty);
               s= Regex.Replace(s, @"\s*/>",string.Empty);
               list.Add(s);
           }           string[] sarr = list.ToArray();
        }

            string ss = " <p> <img height='0' width='0' alt='' src='/project/UserFiles/Image/a.jpg' /> <img height='115' width='140' alt='' src='/project/UserFiles/Image/cgzs/01.jpg' /> </p>" +
" <p> <img height='80' width='120' alt='' src='/project/UserFiles/Image/cgzs/03.jpg' /> </p>";
           MatchCollection mc=  Regex.Matches(ss, @"src=\S*\s*/>");
           List<string> list = new List<string>();
           foreach (Match m in mc)
           {
              
               string s=m.Value.Replace("src='",string.Empty);
               s= Regex.Replace(s, @"'\s*/>",string.Empty);//上面的代码漏了一个'号
               list.Add(s);
           }           string[] sarr = list.ToArray();

try...string ss = " <p> <img height='0' width='0' alt='' src='/project/UserFiles/Image/a.jpg' /> <img height='115' width='140' alt='' src='/project/UserFiles/Image/cgzs/01.jpg' /> </p>" +
" <p> <img height='80' width='120' alt='' src='/project/UserFiles/Image/cgzs/03.jpg' /> </p>"; 
MatchCollection mc = Regex.Matches(ss, @"(?i)<img(?>(?:(?!src=)[^>])*)src=(['""]?)(?<src>[^""'\s>]*)\1[^>]*>");
foreach (Match m in mc)
{
    richTextBox2.Text += m.Groups["src"].Value + "\n";
}

Answer 4

 List<String> lst = new List<sting>(); 
    Regex regex = new Regex(" <img[^>]*src=\"?(? <URL>\\S*)\"?[^>]*>", RegexOptions.IgnoreCase); 
    foreach (Match m in regex.Matches("")) 
    { 
        lst.Add(m.Groups("URL").Value); 
    }
