# If multiple strings are different

Hi,

I have a robot that generates 3 figures (as strings). These should all be different, so I want to include a logic check to ensure this. However, I am a bit stuck…

Basically I want to use an IF A =/= B =/= C, but I don’t know how to right this?

Thanks

Hi,
To use a IF and string comparison in UiPath you can use :

not A.equals( B ) and not A.equals( C ) and not B.equals( C )

Have fun

If StrA, StrB and StrC are your String Variables, then declare a Boolean Variable, say ValidStringFlag. Write an Assign statement as below:

ValidStringFlag = (StrA<>StrB) And (StrA<>StrC) And (StrB<>StrC)

You can have this logic in IF Condition

Not ((strA=strB) or (strB=strC) or (strA=strC))

`A <> B AndAlso A <> C AndAlso B <> C`
I suggest `AndAlso` because it uses short circuit evaluation. If `A = B`, the process will not check the others and determine that the criteria has already failed to be met. This saves on execution time.
FYI the counterpart to this related to karthick’s example is `Not ( A = B OrElse A = C OrElse B = C)`.
since he needs all to be different then he needs the later one: ` Not (A=B OrElse A=C OrElse B=C)`
