double quote inside a double quote

Question

I would like to know how to detect a double quote inside of a double quoted string when I am reading a text file, for example if I have a line likes this

                           text_line ="Project "Comment" Goes Here"


How can I detect the double quote around the word Comment and how can I delete those two double quotes around the word Comment.

Thank you,
Liang

Hi, if you are reading from a text file, then the double quotes would have been escaped.

To check if the string has double quotes you can use:
text_line.Contains("\"");

Here \" will escape the double-quote.

To Remove them you could use:
text_line = text_line.Replace("\"", "'"); // Replace double with single quotes.
text_line = text_line.Replace("\"", " "); // Replace double quotes with a space or u could use an empty string as well

Hi,

Following code might help you. Code written on VS2008.

string s = File.ReadAllText("data.txt");

string[] arr = s.Split('"');

StringBuilder sb = new StringBuilder();

foreach (string str in arr)

{

sb.Append(str);

}

string newStr = sb.ToString();

Asanga.
