spliting string with double new line characters

I have a .txt file, the data of which I have stored in a long string. There are many single new line characters in the string after every line. And there are double new line characters at the end of paragraphs. What I want is to split the string into an array of paragraphs.

what I thought is the following but it is not working

string filePath = "C:\\Users\\Data.txt";
StreamReader readFile = new StreamReader(filePath);
string Data = readFile.ReadToEnd();
string[] paragraphss = Regex.Split(Data, "(^|[^\n])\n{2}(?!\n)");

please help thank you

Inspired by @LueTm's answer and @Traubenfuchs' comment, just making it look compiler friendly and complete. Here's how to split a string with double new line characters:

Data.Split(new string[] { "\r\n\r\n" }, StringSplitOptions.None);

On windows systems the newline character is \r\n, on Unix systems it is \n. This may be why the lines aren't being split, because you're specifically looking for \n\n instead of \r\n\r\n.

You can however use Environment.Newline, which will return the correct newline character for whatever environment the software is running on.

If you're OK with not using regex, Data.Split("\n\n") should do the trick.
