Because the behavior of {0} could vary based on the current user's locale settings, replace this call in {1} with a call to {2}. If the result of {2} will be displayed to the user, such as when sorting a list of items for display in a list box, specify 'StringComparison.CurrentCulture' or 'StringComparison.CurrentCultureIgnoreCase' as the 'StringComparison' parameter. If comparing case-insensitive identifiers, such as file paths, environment variables, or registry keys and values, specify 'StringComparison.OrdinalIgnoreCase'. Otherwise, if comparing case-sensitive identifiers, specify 'StringComparison.Ordinal'.
