Match m1 = Regex.Match(this.richTextBox1.Text, "src=\".*jquery.*\"");
Match m2 = Regex.Match(this.richTextBox1.Text, "src=\".*knockout.*\"");
Match m3 = Regex.Match(this.richTextBox1.Text, "src=\".*priv.*\"");

MessageBox.Show(m4.Value);
MessageBox.Show(this.richTextBox1.Text.Replace(m4.Value, m4.Value + "tt==dd"));

string s = @"<script src=""../../Jscript/jquer5-1.6.4.min.js"" language=""javascript"" type=""text/javascript""></script>";--------------------编程问答-------------------- Regex.Replace(input,@"(?is)(?<=\<script.*?\.js).*?(?=['""])","?dd="+new Random().Next()); --------------------编程问答--------------------
string r = Regex.Replace(s, @"(?is)(?<=<script src=([""']))(.*?)(?=\1)", delegate(Match match)
{
bool b = Regex.IsMatch(match.Groups[2].Value, @"(?i)jquery|knockout|priv");
if (!b)
return match.Groups[2].Value + "?tt=" + DateTime.Now.Ticks;
else
return match.Groups[2].Value;
});
输出r;
