Determines whether the specified IEqualityComparer<T> is a well-known ordinal string comparer.
public:
static bool IsWellKnownOrdinalComparer(System::Collections::Generic::IEqualityComparer<System::String ^> ^ comparer, [Runtime::InteropServices::Out] bool % ignoreCase);public static bool IsWellKnownOrdinalComparer (System.Collections.Generic.IEqualityComparer<string?>? comparer, out bool ignoreCase);static member IsWellKnownOrdinalComparer : System.Collections.Generic.IEqualityComparer<string> * bool -> boolPublic Shared Function IsWellKnownOrdinalComparer (comparer As IEqualityComparer(Of String), ByRef ignoreCase As Boolean) As BooleanParameters
- comparer
- IEqualityComparer<String>
The comparer to query.
- ignoreCase
- Boolean
When this method returns, contains a value stating whether comparer is case-insensitive. Set to false if this method returns false.
Returns
true if comparer is a well-known ordinal string comparer; otherwise, false.
Remarks
A "well-known ordinal comparer" describes a comparer that behaves identically to Ordinal
when passed to Dictionary<TKey,TValue> or HashSet<T>.
For example, Default is a well-known ordinal comparer because
a Dictionary<TKey,TValue> given Default as a constructor
argument will behave identically to a Dictionary<TKey,TValue> given Ordinal
as a constructor argument. If ignoreCase is true on method exit,
then comparer behaves identically to OrdinalIgnoreCase when passed to the
constructor of such a collection.
