Question

I am reading text from a file into a string builder, I make a quick replacement using .Replace(), then I need to run two regex against the string builder to completely overwrite the string builder. What is the best way to do this?

I used Append to initially load the StringBuilder from the streamreader, then used .Replace() for the simple replacement. Now I need to remove the beginning and end of each line based on two different regex.

Answer 1

You will have to convert the StringBuilder into a string (calling its ToString() method) and perform the Regex operations on the string.

Also if you are just interested in reading all text from a file, you don’t need to use a stream and a StringBuilder, instead just use File.ReadAllText(someFile) which returns a string, or File.ReadAllLines(someFile) which returns a string array .
