How do I split a String by another String?

Hi, I am using split function to parse a large file and the delimiter I want to use is "March". Wowever when I run the following script, only the word "M" is used as a delimiter. How can I use the full word "March" instead?

var lines : String[] = html.Split("March"[0]);

See String.Split at MSDN. There's an overload that take `String[]` and `StringSplitOptions`.

var lines = html.Split(["March"], System.StringSplitOptions.RemoveEmptyEntries);
