How to replace the text between two characters in c#

Question

I am bit confused writing the regex for finding the Text between the two delimiters { } and replace the text with another text in c#,how to replace?

Answer 1

To get the string between the parentheses to be replaced, use the Regex pattern

    string errString = "This {match here} uses 3 other {match here} to {match here} the {match here}ation";
    string toReplace =  Regex.Match(errString, @"\{([^\}]+)\}").Groups[1].Value;    
    Console.WriteLine(toReplace); // prints 'match here'  

To then replace the text found you can simply use the Replace method as follows:

string correctString = errString.Replace(toReplace, "document");

Explanation of the Regex pattern:

\{                 # Escaped curly parentheses, means "starts with a '{' character"
        (          # Parentheses in a regex mean "put (capture) the stuff 
                   #     in between into the Groups array" 
           [^}]    # Any character that is not a '}' character
           *       # Zero or more occurrences of the aforementioned "non '}' char"
        )          # Close the capturing group
\}                 # "Ends with a '}' character"
