Answer 1

MatchCollection titleMatch = Regex.Matches(htmlCode,@"<script.*?[^>]*?>",RegexOptions.Singleline | RegexOptions.IgnoreCase);
foreach(Match t in titleMatch )
{
string str_scriptold= t.Groups[0].Value;
string str_jsold=Regex.Match(t,@"<script[^>]*?src=""[^\""|\'].*?[\"",\']");
string str_js=str_jsold.substring(0,str_jsold.length-1);
str_js+="?tt="+datetime.now.tostring();
string str_script=str_scriptold.Replace(str_jsold,str_js);
htmlCode.Replace(str_scriptold,str_script);
}

编译不通报错了

追答

oo 不好意思 在后面加上.Groups[0].Value;

Answer 2

string addCode = "?ccc=ttt";
Regex linkReg = new Regex("<script [^>]*src=\"([^\"]*)\"");
MatchCollection linkCollection = linkReg.Matches(richTextBox1.Text);
foreach (Match linkMatch in linkCollection)
{
richTextBox1.Text = richTextBox1.Text.Replace(linkMatch.Groups[1].Value.Trim(), linkMatch.Groups[1].Value.Trim() + addCode);
}

Answer 3

要用C# 给每一个script 标签中的引用地址加上时间戳如何替换？

例如:
