How can I remove “\r\n” from a string in C#? Can I use a regular expression?

Question

I am trying to persist string from an ASP.NET textarea. I need to strip out the carriage return line feeds and then break up whatever is left into a string array of 50 chara

Here is the perfect method:

Please note that Environment.NewLine works on on Microsoft platforms.

In addition to the above, you need to add \r and \n in a separate function!

Here is the code which will support whether you type on Linux, Windows, or Mac:

var stringTest = "\r Test\nThe Quick\r\n brown fox";

Console.WriteLine("Original is:");
Console.WriteLine(stringTest);
Console.WriteLine("-------------");

stringTest = stringTest.Trim().Replace("\r", string.Empty);
stringTest = stringTest.Trim().Replace("\n", string.Empty);
stringTest = stringTest.Replace(Environment.NewLine, string.Empty);

Console.WriteLine("Output is : ");
Console.WriteLine(stringTest);
Console.ReadLine();
