Split a string by another string in C#

I've been using the Split() method to split strings, but this only appears to work if you are splitting a string by a character. Is there a way to split a string, with another string being the split by parameter?

I've tried converting the splitter into a character array, with no luck.

In other words, I'd like to split the string:

THExxQUICKxxBROWNxxFOX

by xx, and return an array with values:

THE, QUICK, BROWN, FOX

What I have tried:

i tried to use linq but never got the desired response.

The simpler solution is top just use the string overload version: String.Split Method (System) | Microsoft Docs[^]

C#

string data = "THExxQUICKxxBROWNxxFOX";
foreach (string s in data.Split("xx"))
	{
	Console.WriteLine(s);
	}

Paul, i see 2 errors:
1) no closing bracket in foreach line
2) Split method does not accept single string as a parameter (C1503 - cannot convert string to char[]).
Am i wrong?

It was introduced at .NET 6 - check the link.

The missing ")" was a copy'n'paste error - I'll fix it.

Sorry, but i do not see relevant information or override method...

Strange - the link takes me direct to it:

Split(String, StringSplitOptions)
Splits a string into substrings that are based on the provided string separator.

C#

Copy
public string[] Split (string? separator, StringSplitOptions options = System.StringSplitOptions.None);

If you go to the top of the link page, is the .NET version set to ".NET 6"?

Yes, it's really strange. The link takes me direct to Split function and i see .Net 6.0 version on the top of page, but i do not see overide method with single string parameter :(
I'm not using .Net 6.0, so i can not confirm, but i do believe that there's such of version.

Do you see one with two parameters? The second is defaulted ...

Maciej Los 8-Mar-22 11:28am

Check this out on Splt.Net6 | C# Online Compiler | .NET Fiddle[^]. So, i can confirm that the second parameter is default even if i do not see that in the documentation.

That's pretty much identical to what I did to test it - and ion Fiddle as well! :D

Actually, it was added in Core 2.0 - expand the box under "applies to". :)

Maciej Los 8-Mar-22 11:30am

Under "Aplies to" i see all versions of .Net :(

Solution 1

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

C#

string data = "THExxQUICKxxBROWNxxFOX";

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

5ed!
Tip: i'd use: StringSplitOptions.RemoveEmptyEntries as a second parameter of Split function.
