Příklady

Následující příklad kódu vytvoří prázdné Dictionary<TKey,TValue> řetězce s klíči řetězce a přistupuje k němu IDictionary<TKey,TValue> prostřednictvím rozhraní.The following code example creates an empty Dictionary<TKey,TValue> of strings, with string keys, and accesses it through the IDictionary<TKey,TValue> interface.

Příklad kódu používá Add metodu k přidání některých prvků.The code example uses the Add method to add some elements. Příklad ukazuje, že metoda Add je vyvolána ArgumentException při pokusu o přidání duplicitního klíče.The example demonstrates that the Add method throws ArgumentException when attempting to add a duplicate key.

V příkladu se používá Item[TKey] vlastnost (indexer v C#rámci) k načtení hodnot, což KeyNotFoundException demonstruje, že je vyvolána výjimka, když požadovaný klíč není k dispozici, a je-li zobrazeno, že hodnota přidružená ke klíči může být nahrazena.The example uses the Item[TKey] 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.

Příklad ukazuje, jak použít TryGetValue metodu jako efektivnější způsob, jak načíst hodnoty, pokud program často musí vyzkoušet klíčové hodnoty, které nejsou ve slovníku, a jak ContainsKey použít metodu k otestování, zda existuje klíč před voláním metody Addmetoda.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 how to use the ContainsKey method to test whether a key exists prior to calling the Add method.

Nakonec příklad ukazuje, jak vytvořit výčet klíčů a hodnot ve slovníku a jak pomocí Values vlastnosti vytvořit výčet hodnot samostatně.Finally, the example shows how to enumerate the keys and values in the dictionary, and how to enumerate the values alone using the Values property.

Poznámky

IDictionary<TKey,TValue> Rozhraní je základní rozhraní pro obecné kolekce párů klíč/hodnota.The IDictionary<TKey,TValue> interface is the base interface for generic collections of key/value pairs.

Každý prvek je dvojice klíč/hodnota uložená v KeyValuePair<TKey,TValue> objektu.Each element is a key/value pair stored in a KeyValuePair<TKey,TValue> object.

Každý pár musí mít jedinečný klíč.Each pair must have a unique key. Implementace se mohou lišit v závislosti na key tom, nullzda jsou povoleny.Implementations can vary in whether they allow key to be null. Hodnota může být null a nemusí být jedinečná.The value can be null and does not have to be unique. IDictionary<TKey,TValue> Rozhraní umožňuje výčet obsažených klíčů a hodnot, ale nezahrnuje žádné konkrétní pořadí řazení.The IDictionary<TKey,TValue> interface allows the contained keys and values to be enumerated, but it does not imply any particular sort order.

foreach Příkaz C# jazykaFor Each (v C++Visual Basic v)vracíobjekttypuprvkůvkolekci.for eachThe foreach statement of the C# language (For Each in Visual Basic, for each in C++) returns an object of the type of the elements in the collection. Vzhledem k tomu, že IDictionary<TKey,TValue> každý prvek je dvojice klíč/hodnota, typ prvku není typ klíče nebo typ hodnoty.Since each element of the IDictionary<TKey,TValue> is a key/value pair, the element type is not the type of the key or the type of the value. Místo toho je KeyValuePair<TKey,TValue>typ prvku.Instead, the element type is KeyValuePair<TKey,TValue>. Příklad:For example:

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

foreach Příkaz je Obálka kolem čítače, který umožňuje pouze čtení z, nikoli zápis do kolekce.The foreach statement is a wrapper around the enumerator, which only allows reading from, not writing to, the collection.

Poznámka

Vzhledem k Equals tomu, že klíče mohou být zděděny a jejich chování bylo změněno, jejich absolutní jedinečnost nemůže být zaručena porovnáním pomocí metody.Because keys can be inherited and their behavior changed, their absolute uniqueness cannot be guaranteed by comparisons using the Equals method.

Poznámky pro implementátory

Implementující třída musí mít prostředek pro porovnání klíčů.The implementing class must have a means to compare keys.
