BitArray.CopyTo Method

Copies the entire BitArray to a compatible one-dimensional Array, starting at the specified index of the target array.

Namespace:  System.Collections
Assembly:  mscorlib (in mscorlib.dll)

public void CopyTo(
	Array array,
	int index
)

Parameters

array
Type: System.Array
The one-dimensional Array that is the destination of the elements copied from BitArray. The Array must have zero-based indexing.
index
Type: System.Int32
The zero-based index in array at which copying begins.

Implements

ICollection.CopyTo(Array, Int32)

ExceptionCondition
ArgumentNullException

array is null.

ArgumentOutOfRangeException

index is less than zero.

ArgumentException

array is multidimensional.

-or-

The number of elements in the source BitArray is greater than the available space from index to the end of the destination array.

InvalidCastException

The type of the source BitArray cannot be cast automatically to the type of the destination array.

The specified array must be of a compatible type. Only bool, int, and byte types of arrays are supported.

This method uses Array.Copy to copy the elements.

This method is an O(n) operation, where n is Count.

The following code example shows how to copy a BitArray into a one-dimensional Array.


using System;
using System.Collections;
public class SamplesBitArray  {

   public static void Main()  {

      // Creates and initializes the source BitArray.
      BitArray myBA = new BitArray( 4 );
      myBA[0] = myBA[1] = myBA[2] = myBA[3] = true;

      // Creates and initializes the one-dimensional target Array of type Boolean.
      bool[] myBoolArray = new bool[8];
      myBoolArray[0] = false;
      myBoolArray[1] = false;

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

      // Copies the entire source BitArray to the target BitArray, starting at index 3.
      myBA.CopyTo( myBoolArray, 3 );

      // Displays the values of the target Array.
      PrintValues( myBoolArray );

      // Creates and initializes the one-dimensional target Array of type integer.
      int[] myIntArray = new int[8];
      myIntArray[0] = 42;
      myIntArray[1] = 43;

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

      // Copies the entire source BitArray to the target BitArray, starting at index 3.
      myBA.CopyTo( myIntArray, 3 );

      // Displays the values of the target Array.
      PrintValues( myIntArray );

      // Creates and initializes the one-dimensional target Array of type integer.
      Array myByteArray = Array.CreateInstance( typeof(byte), 8 );
      myByteArray.SetValue( (byte) 10, 0 );
      myByteArray.SetValue( (byte) 11, 1 );

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

      // Copies the entire source BitArray to the target BitArray, starting at index 3.
      myBA.CopyTo( myByteArray, 3 );

      // Displays the values of the target Array.
      PrintValues( myByteArray );

      // Returns an exception if the array is not of type Boolean, integer or byte.
      try  {
         Array myStringArray=Array.CreateInstance( typeof(String), 8 );
         myStringArray.SetValue( "Hello", 0 );
         myStringArray.SetValue( "World", 1 );
         myBA.CopyTo( myStringArray, 3 );
      } catch ( Exception myException )  {
         Console.WriteLine("Exception: " + myException.ToString());
      }
   }

   public static void PrintValues( IEnumerable myArr )  {
      foreach ( Object obj in myArr ) {
         Console.Write( "{0,8}", obj );
      }
      Console.WriteLine();
   }

}
