So do it:

\$(?<postdollar>[\w]+)(?<term>\s|$)</term></postdollar>

Will extract the AAAA or BBBB into separate Matches: you can then use replace to change it:

C#

public static Regex regex = new Regex(
      "\\$(?<PostDollar>[\\w]+)(?<Term>\\s|$)",
    RegexOptions.IgnoreCase
    | RegexOptions.Multiline
    | RegexOptions.CultureInvariant
    | RegexOptions.IgnorePatternWhitespace
    | RegexOptions.Compiled
    );
public static string regexReplace = "http://webname/name.aspx?name=${PostDollar}";

string result = regex.Replace(inputText,regexReplace);

Solution 2

Hi Anrew, modified as per your clarification:
Input: "This is so Good $AAAA & $BBBB"
Output: This is So Good AAAA and AABB

C#

Regex reg = new Regex(@"\$[A-Z]*");
string input = "This is So Good $AAAA and $AABB";
string hyperlink;
string value;
string output = input;
foreach (var item in reg.Matches(input))
{
    value = item.ToString().Remove(0,1); // to remove the "$" character
    hyperlink = string.Format("<a href='http://webname/name.aspx?name={0}'>{0}</a>", value);
    output = output.Replace(item.ToString(), hyperlink);
}
Console.WriteLine(output);
//This is So Good <a href='http://webname/name.aspx?name=AAAA'>AAAA</a> and <a href='http://webname/name.aspx?name=AABB'>AABB</a>

that's not what i mean, what i mean is like this.
ex :
string s1 = "this is so Good $AABB and $BBCC".

it become "this is so Good $AABB and $BBCC"
