string split c#

[stefanmz]

hey just a quick question can you use => as string splitter? For some reason in my task it says that the input has to be done like this. You know string.split('=>') it counts it as two symbols is there a button on the keyboard that types this symbol as one symbol? I also tried doing this string.split('=','>') but then when I type both => as a string splitter it breaks for example input=>input and so on

Hacky answer: split on '=' and remove '>' from all resulting strings (or vice versa).

 

EDIT: potentially less hacky: Use a String ("xxx") instead of Character ('x') and see if that works.

I think this is what you are looking for: https://docs.microsoft.com/en-us/dotnet/api/system.string.split?view=net-5.0#System_String_Split_System_Char___

 

So if I am understanding you correctly, you have a string like this:

text1=>text2=>text3=>

And you need to extract text1, text2 and text3?

No I was acttually wondering

yes but I checked this page it doesn't work if I put them as tow symbols = and >

Can you post your code and show the output?

It should probably go like this:

string s = "text1=>text2=>text3=>";
string[] subs = s.Split('=', '>');

with subs now being a string array with these 'text1', etc. strings in it.

So I tried both and it works only after adding this System.StringSplitOptions.RemoveEmptyEntries in the method for string split. I don't know what it does but it works fine so thanks

What's happening if you don't do that is that it's treating the 0-character gap in between the = > as a string:

 

a=>b
'a', '=', '', '>', 'b'

 

so you get a 3-element array instead of 2.

Yes. Read the documentation for string.Split(). Two overloads of this method take a string[] as an argument.

 

var text = "Hello=>here's=>some=>text=>and some symbols: 2=2, 5>4";
var delimiters = new string[] { "=>" };

string[] splittedStrings = text.Split(delimiters, StringSplitOptions.None);

foreach (var part in splittedStrings) Console.WriteLine(part);

// Output:
// Hello
// here's
// some
// text
// and some symbols: 2=2, 5>4

 

 

The suggestions above to split on chars '=' and '>' are not acceptable, because, well, the task is to split on the string "=>", not on chars '=' and '>'.

var text = "Hello=>here's=>some=>text=>and some symbols: 2=2, 5>4";
var separators = new char[] { '=', '>' };

string[] splittedStrings = text.Split(separators, StringSplitOptions.RemoveEmptyEntries);

foreach (var part in splittedStrings) Console.WriteLine(part);

// Output:
// Hello
// here's
// some
// text
// and some symbols: 2
// 2, 5
// 4

Oh I understand thanks for the info!

I'm not sure why you would want to split on => since that's the lambda operator. That's weird.

Because my task from my teacher said input to be done like this. I don't know if he insists on using this or it's just his choice and we can do whatever we want but just in case. Honestly I would have used , but I decided to do it exactly as shown in his example where it was string1=>string2 and his strings were separated by this
