SortedList.CopyTo Method

Copies SortedList elements to a one-dimensional Array object, starting at the specified index in the array.

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

Public Overridable Sub CopyTo ( _
	array As Array, _
	arrayIndex As Integer _


Type: System.Array

The one-dimensional Array object that is the destination of the DictionaryEntry objects copied from SortedList. The Array must have zero-based indexing.

Type: System.Int32

The zero-based index in array at which copying begins.


ICollection.CopyTo(Array, Int32)


array is Nothing.


arrayIndex is less than zero.


array is multidimensional.


The number of elements in the source SortedList object is greater than the available space from arrayIndex to the end of the destination array.


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

The key/value pairs are copied to the Array object in the same order in which the enumerator iterates through the SortedList object.

To copy only the keys in the SortedList, use SortedList.Keys.CopyTo.

To copy only the values in the SortedList, use SortedList.Values.CopyTo.

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

The following code example shows how to copy the values in a SortedList object into a one-dimensional Array object.

   Public Shared Sub Main()

      ' Creates and initializes the source SortedList.

      Console.WriteLine("The target Array contains the following (before and after copying):")
      PrintValues(myTargetArray, " "c)

      ' Copies the entire source SortedList to the target SortedList, starting at index 6.
      mySourceList.CopyTo(myTargetArray, 6)

      ' Displays the values of the target Array.
      PrintValues(myTargetArray, " "c)

'This code produces the following output. 
'The target Array contains the following (before and after copying): 
' The quick brown fox jumped over the lazy dog
