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.

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

public:
SortedDictionary(
	IDictionary<TKey, TValue>^ dictionary
)

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.
