Question

I have string like

[any characters]{$\prime$}[any characters]$[any characters]{$\prime$}[any characters]$[any characters]

I want to replace the $\prime$ that is inside $ “The second one” to be replaced by \prime
so the output from replace is

[any characters]{$\prime$}[any characters]$[any characters]{\prime}[any characters]$[any characters]

How can I do that using Reqex.Replace

and here is the code I use

trannsformContent = Regex.Replace(trannsformContent, @"(\$)(?<cont>.*?)(\$)\\prime(\$)(?<cont1>.*?)(\$)", @"${cont}\prime{cont1}$", RegexOptions.Compiled | RegexOptions.Singleline | RegexOptions.IgnoreCase);

Answer 1

I found the solution :

trannsformContent = Regex.Replace(trannsformContent, @"\${1}(?<cont>.*?)\${1}\\prime\${1}(?<cont1>.*?)\${1}", @"$$${cont}\prime${cont1}$", RegexOptions.Compiled | RegexOptions.Singleline | RegexOptions.IgnoreCase);
