I have a browser text box that my users type into. I am trying the following to split up the contents that they enter by new line. I tried the following but none work. I either get errors or no splitting:

content.Split("\n", StringSplitOptions.None) < gives me an error Error The best overloaded method match for 'string.Split(params char[])' has some invalid arguments    

content.Split('\n', StringSplitOptions.None) < gives an error: The best overloaded method match for 'string.Split(params char[])' has some invalid arguments

content.Split(new[] { Environment.NewLine }, StringSplitOptions.None) < doesn't split as needed. When I look at the source in debugger I just see \n characters. 

content.Split(new[] { "\r\n" }, StringSplitOptions.None) < doesn't split as needed. When I look at the source in debugger I just see \n characters.

Can anyone suggest what I can do?

    Call content.Split correctly:

    content.Split(new [] { "\n" }, StringSplitOptions.None);
content.Split(new [] { '\n' }, StringSplitOptions.None);

    The third option does not work as in a Windows environment Environment.NewLine is “\n\r”, but your sting contains only “\n”.

    In the fourth option you look for “\n\r” again.

    Alternatively you could use 

    content.Split(new [] { '\r', '\n' }, StringSplitOptions.RemoveEmptyEntries);

    This would split on “\r” and “\n” and remove all empty lines.
