SortedDictionary<TKey, TValue> Constructor (IDictionary<TKey, TValue>^)
Initializes a new instance of the SortedDictionary<TKey, TValue> class that contains elements copied from the specified IDictionary<TKey, TValue> and uses the default IComparer<T> implementation for the key type.
Assembly: System (in System.dll)
Parameters
- dictionary
-
Type:
System.Collections.Generic::IDictionary<TKey, TValue>^
The IDictionary<TKey, TValue> whose elements are copied to the new SortedDictionary<TKey, TValue>.
| Exception | Condition |
|---|---|
| ArgumentNullException | dictionary is null. |
| ArgumentException | dictionary contains one or more duplicate keys. |
Every key in a SortedDictionary<TKey, TValue> must be unique according to the default comparer; therefore, every key in the source dictionary must also be unique according to the default comparer.
SortedDictionary<TKey, TValue> requires a comparer implementation to perform key comparisons. This constructor uses the default generic equality comparer, Comparer<T>::Default. If type TKey implements the System::IComparable<T> generic interface, the default comparer uses that implementation. Alternatively, you can specify an implementation of the IComparer<T> generic interface by using a constructor that accepts a comparer parameter.
This constructor is an O(n log n) operation, where n is the number of elements in dictionary.
The following code example shows how to use SortedDictionary<TKey, TValue> to create a sorted copy of the information in a Dictionary<TKey, TValue>, by passing the Dictionary<TKey, TValue> to the SortedDictionary<TKey, TValue>(IComparer<TKey>^) constructor.
