BitArray::And Method (BitArray^)
Performs the bitwise AND operation between the elements of the current BitArray object and the corresponding elements in the specified array. The current BitArray object will be modified to store the result of the bitwise AND operation.
Assembly: mscorlib (in mscorlib.dll)
Parameters
- value
-
Type:
System.Collections::BitArray^
The array with which to perform the bitwise AND operation.
Return Value
Type: System.Collections::BitArray^An array containing the result of the bitwise AND operation, which is a reference to the current BitArray object.
| Exception | Condition |
|---|---|
| ArgumentNullException | value is null. |
| ArgumentException | value and the current BitArray do not have the same number of elements. |
The bitwise AND operation returns true if both operands are true, and returns false if one or both operands are false.
This method is an O(n) operation, where n is Count.
The following code example shows how to perform the bitwise AND 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[ 2 ] = false; myBA2[ 1 ] = true; myBA2[ 3 ] = true; // Performs a bitwise AND 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( "AND:" ); PrintValues( myBA1->And( myBA2 ), 8 ); Console::WriteLine(); Console::WriteLine( "After AND" ); Console::Write( "myBA1:" ); PrintValues( myBA1, 8 ); Console::Write( "myBA2:" ); PrintValues( myBA2, 8 ); Console::WriteLine(); // Performing AND 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->And( myBA3 ); } catch ( Exception^ myException ) { Console::WriteLine( "Exception: {0}", myException ); } } void PrintValues( IEnumerable^ myList, int myWidth ) { int i = myWidth; IEnumerator^ myEnum = myList->GetEnumerator(); while ( myEnum->MoveNext() ) { Object^ obj = safe_cast<Object^>(myEnum->Current); if ( i <= 0 ) { i = myWidth; Console::WriteLine(); } i--; Console::Write( "{0,8}", obj ); } Console::WriteLine(); } /* This code produces the following output. Initial values myBA1: False False True True myBA2: False True False True Result AND: False False False True After AND myBA1: False False False True myBA2: False True False True Exception: System.ArgumentException: Array lengths must be the same. at System.Collections.BitArray.And(BitArray value) at SamplesBitArray.Main() */
