ctigeek / Split.cs

Last active January 24, 2019 15:16

Split a string on a character, but don't split based on start-end characters.

	/// <summary>
	/// Split a string while preserving sections of it.
	/// Similar to string.Split, but you can define start-end characters (e.g. quotes, brackets, braces) inside of which it will NOT split.
	/// Preservers can also be "recursive" which means it can determine if it's in nested brackets or parens, etc.
	/// If the start & end characters are different, there's a good chance you want to set recursive to true.
	/// See the associated unit test for an example that can parse json....
	/// Also supports escape characters so the separator and start-end characters can be ignored.
	/// </summary>
