String::Equals Method (String, String, StringComparison)

Determines whether two specified String objects have the same value. A parameter specifies the culture, case, and sort rules used in the comparison.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

public:
static bool Equals(
	String^ a, 
	String^ b, 
	StringComparison comparisonType
)

Parameters

a
Type: System::String

The first string to compare, or nullptr.

b
Type: System::String

The second string to compare, or nullptr.

comparisonType
Type: System::StringComparison

One of the enumeration values that specifies the rules for the comparison.

Return Value

Type: System::Boolean
true if the value of the a parameter is equal to the value of the b parameter; otherwise, false.

ExceptionCondition
ArgumentException

comparisonType is not a StringComparison value.

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 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.
