I'm using code similar to the following to search a line of code. I want to
replace what was found with a modified version of the text. My regex
pattern is "ListView\w *". And the line of text that I am matching against
is: "public static void AutoSizeListVie w(ref ListView lv)". My RegEx finds
two matches but I want the resulting string to look like:
public static void AutoSize%TG%Lis tView%TG%(ref %TG%ListView%TG % lv)
As you can see - I'm replacing the text that was found with the same text
but with a "%TG%" on the front and behind the text. I'm not quite sure how
to take my match value and use it again in the replace. Can someone help me
out?
Thanks!
Brian

Use the key characters '$&' to refer to the 'match found string'
string text = "public static void AutoSizeListVie w(ref ListView lv)";
string pattern = @"ListView\w *";
text = Regex.Replace(t ext, pattern, "%TG%$&%TG% ");
