BitArray.Or(BitArray) BitArray.Or(BitArray) BitArray.Or(BitArray) BitArray.Or(BitArray) Method

定義

現在の BitArray オブジェクトの要素と指定した配列内の対応する要素の間で、ビットごとの OR 演算を実行します。Performs the bitwise OR operation between the elements of the current BitArray object and the corresponding elements in the specified array. 現在の BitArray オブジェクトが変更され、ビットごとの OR 演算の結果を格納します。The current BitArray object will be modified to store the result of the bitwise OR operation.

public:
 System::Collections::BitArray ^ Or(System::Collections::BitArray ^ value);
public System.Collections.BitArray Or (System.Collections.BitArray value);
member this.Or : System.Collections.BitArray -> System.Collections.BitArray
Public Function Or (value As BitArray) As BitArray

パラメーター

value
BitArray BitArray BitArray BitArray

ビットごとの OR 演算の実行対象となる配列。The array with which to perform the bitwise OR operation.

戻り値

ビットごとの OR 演算の結果を含み、現在の BitArray オブジェクトへの参照である配列。An array containing the result of the bitwise OR operation, which is a reference to the current BitArray object.

例外

value の要素数と現在の BitArray の要素数が異なります。value and the current BitArray do not have the same number of elements.

次のコード例は、2 つの OR 演算を実行する方法を示しますBitArrayオブジェクト。The following code example shows how to perform the OR operation between two BitArray objects.

using namespace System;
using namespace System::Collections;
void PrintValues( IEnumerable^ myList, int myWidth );
int main()
{
   
   // Creates and initializes two BitArrays of the same size.
   BitArray^ myBA1 = gcnew BitArray( 4 );
   BitArray^ myBA2 = gcnew BitArray( 4 );
   myBA1[ 0 ] = false;
   myBA1[ 1 ] = false;
   myBA1[ 2 ] = true;
   myBA1[ 3 ] = true;
   myBA2[ 0 ] = false;
   myBA2[ 1 ] = true;
   myBA2[ 2 ] = false;
   myBA2[ 3 ] = true;
   
   // Performs a bitwise OR operation between BitArray instances of the same size.
   Console::WriteLine( "Initial values" );
   Console::Write( "myBA1:" );
   PrintValues( myBA1, 8 );
   Console::Write( "myBA2:" );
   PrintValues( myBA2, 8 );
   Console::WriteLine();
   Console::WriteLine( "Result" );
   Console::Write( "OR:" );

   Console::WriteLine();
   Console::WriteLine( "After OR" );
   Console::Write( "myBA1:" );
   PrintValues( myBA1, 8 );
   Console::Write( "myBA2:" );
   PrintValues( myBA2, 8 );
   Console::WriteLine();
   
   // Performing OR between BitArray instances of different sizes returns an exception.
   try
   {
      BitArray^ myBA3 = gcnew BitArray( 8 );
      myBA3[ 0 ] = false;
      myBA3[ 1 ] = false;
      myBA3[ 2 ] = false;
      myBA3[ 3 ] = false;
      myBA3[ 4 ] = true;
      myBA3[ 5 ] = true;
      myBA3[ 6 ] = true;
      myBA3[ 7 ] = true;
      myBA1->Or( myBA3 );
   }
   catch ( Exception^ myException ) 
   {
      Console::WriteLine( "Exception: {0}", myException );
   }

}

{
   int i = myWidth;
   IEnumerator^ myEnum = myList->GetEnumerator();

   {
      Object^ obj = safe_cast<Object^>(myEnum->Current);

         Console::WriteLine();
      }

      i--;

   }

   Console::WriteLine();

注釈

ビットごとの OR 演算を返しますtrue場合は 1 つまたは両方のオペランドがtrue、し、返しますfalse場合、両方のオペランドがfalseします。The bitwise OR operation returns true if one or both operands are true, and returns false if both operands are false.

このメソッドは O (n) 操作、nCountします。This method is an O(n) operation, where n is Count.
