Queue.CopyTo(Array, Int32) Metode

Definisi

Ruang nama:

System.Collections

Rakitan:

System.Collections.NonGeneric.dll

Sumber:

Queue.cs

Queue Menyalin elemen ke satu dimensi Arrayyang ada, dimulai pada indeks array yang ditentukan.

public:
 virtual void CopyTo(Array ^ array, int index);

public virtual void CopyTo (Array array, int index);

abstract member CopyTo : Array * int -> unit
override this.CopyTo : Array * int -> unit

Public Overridable Sub CopyTo (array As Array, index As Integer)

Parameter

array

Array

Satu dimensi Array yang merupakan tujuan elemen yang disalin dari Queue. Array harus memiliki pengindeksan berbasis nol.

index

Int32

Indeks berbasis nol tempat array penyalinan dimulai.

Penerapan

CopyTo(Array, Int32)

Pengecualian

ArgumentNullException

arrayadalah null.

ArgumentOutOfRangeException

index kurang dari nol.

ArgumentException

array bersifat multidmensional.

-atau-

Jumlah elemen dalam sumber Queue lebih besar dari ruang yang tersedia dari index ke akhir tujuan array.

ArrayTypeMismatchException

Jenis sumber Queue tidak dapat dilemparkan secara otomatis ke jenis tujuan array.

Contoh

Contoh berikut menunjukkan cara menyalin Queue ke dalam array satu dimensi.

using namespace System;
using namespace System::Collections;
void PrintValues( Array^ myArr, char mySeparator );
int main()
{
   // Creates and initializes the source Queue.
   Queue^ mySourceQ = gcnew Queue;
   mySourceQ->Enqueue( "three" );
   mySourceQ->Enqueue( "napping" );
   mySourceQ->Enqueue( "cats" );
   mySourceQ->Enqueue( "in" );
   mySourceQ->Enqueue( "the" );
   mySourceQ->Enqueue( "barn" );

   // Creates and initializes the one-dimensional target Array.
   Array^ myTargetArray = Array::CreateInstance( String::typeid, 15 );
   myTargetArray->SetValue( "The", 0 );
   myTargetArray->SetValue( "quick", 1 );
   myTargetArray->SetValue( "brown", 2 );
   myTargetArray->SetValue( "fox", 3 );
   myTargetArray->SetValue( "jumps", 4 );
   myTargetArray->SetValue( "over", 5 );
   myTargetArray->SetValue( "the", 6 );
   myTargetArray->SetValue( "lazy", 7 );
   myTargetArray->SetValue( "dog", 8 );

   // Displays the values of the target Array.
   Console::WriteLine( "The target Array contains the following (before and after copying):" );
   PrintValues( myTargetArray, ' ' );

   // Copies the entire source Queue to the target Array, starting at index 6.
   mySourceQ->CopyTo( myTargetArray, 6 );

   // Displays the values of the target Array.
   PrintValues( myTargetArray, ' ' );

   // Copies the entire source Queue to a new standard array.
   array<Object^>^myStandardArray = mySourceQ->ToArray();

   // Displays the values of the new standard array.
   Console::WriteLine( "The new standard array contains the following:" );
   PrintValues( myStandardArray, ' ' );
}

void PrintValues( Array^ myArr, char mySeparator )
{
   IEnumerator^ myEnum = myArr->GetEnumerator();
   while ( myEnum->MoveNext() )
   {
      Object^ myObj = safe_cast<Object^>(myEnum->Current);
      Console::Write( "{0}{1}", mySeparator, myObj );
   }

   Console::WriteLine();
}

Keterangan

Elemen disalin ke Array dalam urutan yang sama di mana enumerator melakukan iterasi melalui Queue.

Metode ini adalah O(n) operasi, di mana n adalah Count.
