Split a string by another string in C#

In order to split by a string you'll have to use the string array overload.

string data = "THExxQUICKxxBROWNxxFOX";

return data.Split(new string[] { "xx" }, StringSplitOptions.None);

There is an overload of Split that takes strings.

"THExxQUICKxxBROWNxxFOX".Split(new [] { "xx" }, StringSplitOptions.None);

You can use either of these StringSplitOptions

• None - The return value includes array elements that contain an empty string
• RemoveEmptyEntries - The return value does not include array elements that contain an empty string

So if the string is "THExxQUICKxxxxBROWNxxFOX", StringSplitOptions.None will return an empty entry in the array for the "xxxx" part while StringSplitOptions.RemoveEmptyEntries will not.

Regex.Split(string, "xx")

is the way I do it usually.

Of course you'll need:

using System.Text.RegularExpressions;

or :

System.Text.RegularExpressions.Regex.Split(string, "xx")

but then again I need that library all the time.
