Comparer Class

Compares two objects for equivalence, where string comparisons are case-sensitive.

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

public final class Comparer implements IComparer, ISerializable

This class is the default implementation of the IComparer interface. The CaseInsensitiveComparer class is the implementation of the IComparer interface that performs case-insensitive string comparisons.

Comparison procedures use the Thread.CurrentCulture of the current thread unless otherwise specified. String comparisons might have different results depending on the culture. For more information on culture-specific comparisons, see the System.Globalization namespace and Encoding and Localization.

The following code example shows how Compare returns different values depending on the culture associated with the Comparer.
