Question

I need to split a string based on some character array of separators and not lose these separators in string. I.e.:

string: "Hello world!"
separators: " !"
result: ("Hello", " ", "world", "!")

Of course, i can write something that goes through that string and returns me needed result, but isn’t there something already allowing me to do this, like magically configured String.Split?

Upd: I need to solution without regexp, because it is very slow for me.

Use regular expression:

string[] parts = Regex.Split(myString, yourPattern);

Test:

string[] parts = Regex.Split("Hello World!", "(!| )");

output:

Hello
" "//just space
World
!
""//empty string
