I am porting an existing application to C# and want to improve performance wherever possible. Many existing loop counters and array references are defined as System.UInt32, instead of the Int32 I would have used.
Is there any significant performance difference for using UInt32 vs Int32?
I don’t think there are any performance considerations, other than possible difference between signed and unsigned arithmetic at the processor level but at that point I think the differences are moot.
The bigger difference is in the CLS compliance as the unsigned types are not CLS compliant as not all languages support them.
