i am trying to get the string input from an input field after its sent then compare it to a string from an csv excel file. i am debugging and they have the same values but when i run the code it doesnt work. pls help
#Comparing 2 strings
violet wren
have you tried .Equals()?
neat bobcat
like ras.Equals(rs)?
violet wren
ye
violet wren
how about with tostring?
violet wren
damn yeah im not sure
neat bobcat
how would u compare an input text with a string
maybe my method is worng
maybe the way i am taking the input
violet wren
yeah see what rasp.text gives
violet wren
Debug.Log()
neat bobcat
:)))
i didnt use unity in such long time
kinda ashamed
k ima run and lets see
returns 2
and i entered 2
and the other string is 2
mild stag
make sure it's exactly the same. a string with spaces would not be considered equal. i.e. "2" is not equal to "2 " (and when it's in something like a text box, that kind of thing is easy to miss)
mild stag
and still shown as not equal?
neat bobcat
yep
mild stag
🤔
okay try this
Debug.Log(BitConverter.ToString(THE_STRING.Select(c => (byte)c).ToArray()));
Replace THE_STRING with the name of the string. This will output the bytes of the string, in numeric form
maybe there's a hidden whitespace char or something
neat bobcat
imported both but the select still isnt ok
mild stag
👍
Run it, and it should print out the bytes in hex form
and you can then compare that with the bytes of the other string
neat bobcat
mild stag
there ya go
0B is the ASCII code for a vertical tab
so there was a crafty hidden whitespace character there
neat bobcat
how do i delete it?
mild stag
go to the text box, hit Ctrl+A to select all of it, and hit Delete. and then just enter 2
mild stag
working now?
neat bobcat
but whenever i enter sum it puts the whitespace back
mild stag
🤨
mild stag
I wonder too
neat bobcat
should i just delte the input and put it back?
mild stag
but for hacky workaround: you could just Trim the strings. foo.Trim() will return foo but with all whitespace removed from the start and end of the string
but a better solution is finding out why vertical tab gets put there in the first place
neat bobcat
whitespace doesnt mean a normal space, right?
mild stag
whitespace includes anything that isn't a visible character. so space, tab, new line, stuff like that
anything that's considered a "space" in some form
mild stag
well that's just a space
neat bobcat
so it gets erased?
mild stag
so "this string " will turn into "this string"
mild stag
I've used C# for a very long time 
neat bobcat
thank you so much
mild stag
you're welcome
neat bobcat
i havent even tested it but i am so thankful
mild stag
I'd still try and find the cause for the space being there in the first place, but Trimming it will do the job even if it's very hacky
mild stag
hm?
mild stag
what are you logging
neat bobcat
Debug.Log(BitConverter.ToString(THE_STRING.Select(c => (byte)c).ToArray()));```the thing u sent me
mild stag
are you logging the original text, or the trimmed text?
because the trimmed text should match
neat bobcat
the trimmed
mild stag
Debug.Log(BitConverter.ToString(ras.Select(c => (byte)c).ToArray()));
Debug.Log(BitConverter.ToString(rs.Select(c => (byte)c).ToArray()));
(after trimming both)
neat bobcat
neat bobcat
should i just delete the input and make another one?
mild stag
well this is certainly an interesting problem after all
that vertical tab has no right being here 
I have no idea why it's there but I'm gonna go ahead and blame Unity
mild stag
should i just delete the input and make another one?
I mean it's worth a shot, at this point
neat bobcat
ok it might take a while but i will msg under the thread the results
mild stag
cool 👍
mild stag
there's no harm in it if you don't need it
neat bobcat
ok so
in an input field
there is the input field as a parent
then a text placeholder and a text
i am getting the input from the text one, no?
mild stag
yes but you shouldn't need to do worry, if you get a reference to the root text object you can just do .text
neat bobcat
well then i got the same problem
ok so i found sum interesting
the problem stays if i am looking at the text under the input field
but i read the input field then there is no whitespace
that blue little line form the second picture is the whitespcae
space
mild stag
what on earth
neat bobcat
how do i take the text from the input

Check it out. All your answers in one place
severe raven
I will
and as per your post title you can compare two strings in various was
let s1 and s2 be two strings to be compared
string.Equals(s1, s2)//returns boolean
string.Equals(s1, s2, StringComparison.OrdinalIgnoreCase)//returns boolean
string.Compare(s1,s2)//returns integer compares them lexicographically
string.Compare(s1,s2, true)//returns integer compares them lexicographically```
Or you may create your own methods for comparing them. a protype would be to compare them lexicographically using for loop by extracting each character.
leaden marlin
have you tried .Equals()?
why would that work any different?
violet wren
was just throwing ideas 😂
leaden marlin
but like the == operator calls .Equals
so there's no reason they would work any different

This isn't Java
I have absolutely no idea why you're giving Java examples in #1006674323458764851
severe raven
This isn't Java
Shit!! Sorry!! I am changing it.
mild stag
You can also use a StringComparison value for Compare
In fact there's quite a few overloads
https://learn.microsoft.com/en-us/dotnet/api/system.string.compare
https://learn.microsoft.com/en-us/dotnet/api/system.string.equals
severe raven
but like the == operator calls .Equals
== fails drastically for string. works for char and int. Don't ask for the explanation. IDK, but it is a practical experience of mine....... 🙂
leaden marlin
personal experience is not evidence

it doesn't fail at all. it literally calls .Equals. a == b is identical to string.Equals(a, b) or a.Equals(b)
soft dune
NB: a.Equals(b) is the only one from the lot that will throw a NullReferenceException if a is null.
neat bobcat
ok so
what am i suposed to try?
for anyone wondering how to solve this i did it
just takee the text from the imput field and not from the text child of the input field
thanks to everyone who helped me
mild stag
I said to do that
mild stag
yes but you shouldn't need to do worry, if you get a reference to the root text ...
get a reference to the root text object
