Easiest way to split a string on newlines in .NET?

I need to split a string into newlines in .NET and the only way I know of to split strings is with the Split method. However that will not allow me to (easily) split on a newline, so what is the best way to do it?

To split on a string you need to use the overload that takes an array of strings:

string[] lines = theText.Split(
    new[] { Environment.NewLine },
    StringSplitOptions.None
);

Edit:
If you want to handle different types of line breaks in a text, you can use the ability to match more than one string. This will correctly split on either type of line break, and preserve empty lines and spacing in the text:

string[] lines = theText.Split(
    new[] { "rn", "r", "n" },
    StringSplitOptions.None
);

怎么样使用StringReader ？

using (System.IO.StringReader reader = new System.IO.StringReader(input)) {
    string line = reader.ReadLine();
}

你应该能够很容易地分割你的字符串，就像这样：

aString.Split(Environment.NewLine.ToCharArray());
