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

public interface IComparer<T>
J# supports the use of generic types and methods, but not the declaration of new ones.
JScript does not support generic types and methods.
Not applicable.

Type Parameters

T

The type of objects to compare.

This interface is used with the System.Collections.Generic.List.Sort and System.Collections.Generic.List.BinarySearch methods. It provides a way to customize the sort order of a collection. Classes that implement this interface include the SortedDictionary and SortedList generic classes.

The default implementation of this interface is the Comparer class. The StringComparer class implements this interface for type String.

This interface supports ordering comparisons. That is, when the Compare method returns 0, it means that two objects sort the same. Implementation of exact equality comparisons is provided by the IEqualityComparer generic interface.
