Description

Array Copy(Array, Array, Int64) copies a range of elements from an Array starting at the first element and pastes them into another Array starting at the first element. The length is specified as a 64-bit integer.

Syntax

Array.Copy(Array, Array, Int64) has the following syntax.

public static void Copy(
  Array sourceArray,/*from w  w w  .j  a  v  a  2  s  .  c  om*/
  Array destinationArray,
  long length
)

Parameters

Array.Copy(Array, Array, Int64) has the following parameters.

• sourceArray - The Array that contains the data to copy.
• destinationArray - The Array that receives the data.
• length - A 64-bit integer that represents the number of elements to copy. The integer must be between zero and Int32.MaxValue, inclusive.

Returns

Array.Copy(Array, Array, Int64) method returns

Example

/* ww w .jav  a2  s. c om*/
using System;
public class SamplesArray  {
   public static void Main()  {
      Array myIntArray=Array.CreateInstance( typeof(System.Int32), 5 );
      for ( int i = myIntArray.GetLowerBound(0); i <= myIntArray.GetUpperBound(0); i++ )
         myIntArray.SetValue( i+1, i );

      Array myObjArray = Array.CreateInstance( typeof(System.Object), 5 );
      for ( int i = myObjArray.GetLowerBound(0); i <= myObjArray.GetUpperBound(0); i++ )
         myObjArray.SetValue( i+26, i );

      Array.Copy( myIntArray, myObjArray, 2 );


   }
}

The code above generates the following result.
