Normalize newlines in C#

Question

I have a data stream that may contain \\r, \\n, \\r\\n, \\n\\r or any combination of them. Is there a simple way to normalize the data to make all of them simply become \\r

Answer 1

It's a two step process.
First you convert all the combinations of \r and \n into a single one, say \r
Then you convert all the \r into your target \r\n

normalized = 
    original.Replace("\r\n", "\r").
             Replace("\n\r", "\r").
             Replace("\n", "\r").
             Replace("\r", "\r\n"); // last step

Answer 2

I agree Regex is the answer, however, everyone else fails to mention Unicode line separators. Those (and their variations with \n) should be included.
