SortedList<TKey, TValue> Constructor (IComparer<TKey>^)

 

Initializes a new instance of the SortedList<TKey, TValue> class that is empty, has the default initial capacity, and uses the specified IComparer<T>.

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

public:
SortedList(
	IComparer<TKey>^ comparer
)

Parameters

comparer
Type: System.Collections.Generic::IComparer<TKey>^

The IComparer<T> implementation to use when comparing keys.

-or-

null to use the default Comparer<T> for the type of the key.

Every key in a SortedList<TKey, TValue> must be unique according to the specified comparer.

This constructor uses the default value for the initial capacity of the SortedList<TKey, TValue>. To set the initial capacity, use the SortedList<TKey, TValue>(Int32, IComparer<TKey>^) constructor. If the final size of the collection can be estimated, specifying the initial capacity eliminates the need to perform a number of resizing operations while adding elements to the SortedList<TKey, TValue>.

This constructor is an O(1) operation.

The following code example creates a sorted list with a case-insensitive comparer for the current culture. The example adds four elements, some with lower-case keys and some with upper-case keys. The example then attempts to add an element with a key that differs from an existing key only by case, catches the resulting exception, and displays an error message. Finally, the example displays the elements in case-insensitive sort order.

No code example is currently available or this language may not be supported.
