String.Equals Method (String, StringComparison)
Determines whether this string and a specified String object have the same value. A parameter specifies the culture, case, and sort rules used in the comparison.
Assembly: mscorlib (in mscorlib.dll)
- Type: System.String
The string to compare to this instance.
- Type: System.StringComparison
One of the enumeration values that specifies how the strings will be compared.
Return ValueType: System.Boolean
true if the value of the value parameter is the same as this string; otherwise, false.
The following example creates a string array that consists of an uppercase "I", a lowercase "i", and a dotless "ı". It then calls the method to compare them by using each possible StringComparison enumeration value.
The following example compares four sets of words by using each member of the StringComparison enumeration. The comparisons use the conventions of the English (United States) and Sami (Upper Sweden) cultures. Note that the strings "encyclopædia" and "encyclopedia" are considered equivalent in the en-US culture but not in the Sami (Northern Sweden) culture.
