text中img标签：
匹配img标签的正则表达式：string Pattern = @"]*/s*src/s*=/s*([']?)(?/S+)'?[^>]*>";
匹配img 的src的正则表达式：string Pattern = @"(?<=src/s*=/s*[/'/""]?)(?[http/:]?[^'""]+)";
获取text中img的src地址：
string Pattern = @"(?<=src/s*=/s*[/'/""]?)(?[http/:]?[^'""]+)";
Regex reg = new Regex(Pattern, RegexOptions.IgnoreCase);
MatchCollection colMatch = reg.Matches(text文本);
StringBuilder strImage = new StringBuilder();
if (colMatch.Count > 0)
{
foreach (Match m in colMatch)
{
strImage.Append(m.Value).Append(',');
}
}
匹配text的img,并给img标签加上链接
string Pattern = @"]*/s*src/s*=/s*([']?)(?/S+)'?[^>]*>";
Regex reg = new Regex(Pattern, RegexOptions.IgnoreCase);
MatchEvaluator myEvaluator=new MatchEvaluator(RepleaceReg);
string content = reg.Replace(text文本), myEvaluator);
RepleaceReg函数:
private string RepleaceReg(Match m)
{
string result=m.ToString();
if (albumid != -1)
{
result="" + m + "";} return result;}
