Remarks

The SortedDictionaryTKey, TValue generic class is a binary search tree with O(log n) retrieval, where n is the number of elements in the dictionary. In this respect, it is similar to the SortedListTKey, TValue generic class. The two classes have similar object models, and both have O(log n) retrieval. Where the two classes differ is in memory use and speed of insertion and removal:

Each key/value pair can be retrieved as a KeyValuePairTKey, TValue structure, or as a DictionaryEntry through the nongeneric IDictionary interface.

Keys must be immutable as long as they are used as keys in the SortedDictionaryTKey, TValue. Every key in a SortedDictionaryTKey, TValue must be unique. A key cannot be , but a value can be, if the value type TValue is a reference type.

SortedDictionaryTKey, TValue requires a comparer implementation to perform key comparisons. You can specify an implementation of the IComparerT generic interface by using a constructor that accepts a comparer parameter; if you do not specify an implementation, the default generic comparer ComparerTDefault is used. If type TKey implements the SystemIComparableT generic interface, the default comparer uses that implementation.

The foreach statement of the C# language (for each in C++, For Each in Visual Basic) requires the type of each element in the collection. Since each element of the SortedDictionaryTKey, TValue is a key/value pair, the element type is not the type of the key or the type of the value. Instead, the element type is KeyValuePairTKey, TValue. The following code shows C#, C++, and Visual Basic syntax.

For Each kvp As KeyValuePair(Of String, String) In myDictionary
    Console.WriteLine("Key = {0}, Value = {1}", kvp.Key, kvp.Value)
Next kvp
foreach( KeyValuePair<string, string> kvp in myDictionary )
{
    Console.WriteLine("Key = {0}, Value = {1}", kvp.Key, kvp.Value);
}
for each(KeyValuePair<String^, String^> kvp in myDictionary)
{
    Console::WriteLine("Key = {0}, Value = {1}", kvp.Key, kvp.Value);
}

The foreach statement is a wrapper around the enumerator, which allows only reading from the collection, not writing to it.

Examples

The following code example creates an empty SortedDictionaryTKey, TValue of strings with string keys and uses the Add method to add some elements. The example demonstrates that the Add method throws an ArgumentException when attempting to add a duplicate key.

The example uses the Item property (the indexer in C#) to retrieve values, demonstrating that a KeyNotFoundException is thrown when a requested key is not present, and showing that the value associated with a key can be replaced.

The example shows how to use the TryGetValue method as a more efficient way to retrieve values if a program often must try key values that are not in the dictionary, and it shows how to use the ContainsKey method to test whether a key exists before calling the Add method.

The example shows how to enumerate the keys and values in the dictionary and how to enumerate the keys and values alone using the Keys property and the Values property.

Finally, the example demonstrates the Remove method.

Thread Safety

Public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.

A SortedDictionaryTKey, TValue can support multiple readers concurrently, as long as the collection is not modified. Even so, enumerating through a collection is intrinsically not a thread-safe procedure. To guarantee thread safety during enumeration, you can lock the collection during the entire enumeration. To allow the collection to be accessed by multiple threads for reading and writing, you must implement your own synchronization.
