Code Inspection: String.LastIndexOf is culture-specific
Similarly to the Specify a culture in string conversion explicitly, this inspection helps to avoid problems with running your code on machines with different culture settings.
When strings are compared using String.LastIndexOf
, comparison results may differ depending on the machine's locale. The canonical example is the Turkish where there is a lowercase dotless "ı" with the corresponding uppercase "I", and a lowercase "i" with an uppercase "İ" with the dot. As a result, your code may return different results on machines with different culture settings.
To resolve this problem, ReSharper suggests adding the culture-invariant StringComparison.Ordinal
explicitly to the method call.
