Regex for string in C#

I have string on C#: string buf = "\r\n \r\n \r\n 103E\r\n \r\n \r\n \r\n \r\n \r\ntest1 \r\n \r\n \r\n test2\r\n \r\n \r\n \r\n \r\n 开发者_开发百科 \r\n \r\n \r\n \r\n  x16\r\n \r\n"

I want to get the strings

1. 103E
2. test1
3. test2
4. 16

How to do it using regex.

Try this:

var separator = new string[] { "\r", "\n", " ", " " };
var result = buf.Split(separator, StringSplitOptions.RemoveEmptyEntries);
// result == { "103E", "test1", "test2", "x16" }

Note that, if your input is arbitrary HTML, you should use an HTML parser.

\S+ will match one or more non-whitespace characters. That should get you started.
