Ejemplos

En el ejemplo de código siguiente se muestra cómo se puede copiar StringDictionary en una matriz.The following code example shows how a StringDictionary can be copied to an array.

#using <System.dll>

using namespace System;
using namespace System::Collections;
using namespace System::Collections::Specialized;
void main()
{
   
   // Creates and initializes a new StringDictionary.
   StringDictionary^ myCol = gcnew StringDictionary;
   myCol->Add( "red", "rojo" );
   myCol->Add( "green", "verde" );
   myCol->Add( "blue", "azul" );
   
   // Displays the values in the StringDictionary.
   Console::WriteLine( "KEYS\tVALUES in the StringDictionary" );
   IEnumerator^ myEnum = myCol->GetEnumerator();
   while ( myEnum->MoveNext() )
   {
      DictionaryEntry^ myDE = safe_cast<DictionaryEntry^>(myEnum->Current);
      Console::WriteLine( "{0}\t{1}", myDE->Key, myDE->Value );
      Console::WriteLine();
      
      // Creates an array with DictionaryEntry elements.
      array<DictionaryEntry>^myArr = gcnew array<DictionaryEntry>(3);
      
      // Copies the StringDictionary to the array.
      myCol->CopyTo( myArr, 0 );
      
      // Displays the values in the array.

         Console::WriteLine( "{0}\t{1}", myArr[ i ].Key, myArr[ i ].Value );
      Console::WriteLine();
   }

CopyTo copia objetos a los que se puede convertir System.Collections.DictionaryEntry .CopyTo copies objects that can be typecast to System.Collections.DictionaryEntry. DictionaryEntry contiene la clave y el valor.DictionaryEntry contains both the key and the value.

Los elementos copiados en Array se ordenan en el mismo orden en que el enumerador recorre en iteración StringDictionary .The elements copied to the Array are sorted in the same order that the enumerator iterates through the StringDictionary.

Este método es una operación O ( n ), donde n es Count .This method is an O(n) operation, where n is Count.
