When the CaseInsensitiveComparer instance is created using the parameterless constructor, the Thread.CurrentCulture of the current thread is saved. Comparison procedures use the saved culture to determine the sort order and casing rules; therefore, string comparisons might have different results depending on the culture. For more information on culture-specific comparisons, see the System.Globalization namespace and Globalizing and Localizing .NET Framework Applications.
