The `comparisonType` parameter indicates whether the comparison should use the current or invariant culture, honor or ignore the case of the two strings being compared, or use word or ordinal sort rules.

The following example compares four sets of words by using each member of the <xref:System.StringComparison> enumeration. The comparisons use the conventions of the English (United States) and Sami (Upper Sweden) cultures. Note that the strings "encyclopædia" and "encyclopaedia" are considered equivalent in the en-US culture but not in the Sami (Northern Sweden) culture.

The following example compares three sets of strings by using each member of the <xref:System.StringComparison> enumeration. The comparisons use the conventions of the English (United States), Thai (Thailand) and Turkish (Turkey) cultures. Note that the strings "a" and "a-" are considered equivalent in the "th-TH" culture but not in the others, while "i" and "İ" are considered equivalent in the "tr-TR" culture when case is ignored but not in the other cultures.
