Array.GetValue Method (Int64, Int64)

Gets the value at the specified position in the two-dimensional Array. The indexes are specified as 64-bit integers.

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

'Declaration
<ComVisibleAttribute(False)> _
Public Function GetValue ( _
	index1 As Long, _
	index2 As Long _
) As Object
'Usage
Dim instance As Array 
Dim index1 As Long 
Dim index2 As Long 
Dim returnValue As Object 

returnValue = instance.GetValue(index1, _
	index2)

Parameters

index1
Type: System.Int64

A 64-bit integer that represents the first-dimension index of the Array element to get.

index2
Type: System.Int64

A 64-bit integer that represents the second-dimension index of the Array element to get.

Return Value

Type: System.Object
The value at the specified position in the two-dimensional Array.

ExceptionCondition
ArgumentException

The current Array does not have exactly two dimensions.

ArgumentOutOfRangeException

Either index1 or index2 is outside the range of valid indexes for the corresponding dimension of the current Array.

The GetLowerBound and GetUpperBound methods can determine whether any of the indexes is out of bounds.

This method is an O(1) operation.

The following code example demonstrates how to set and get a specific value in a one-dimensional or multidimensional array.

Imports System

Public Class SamplesArray

   Public Shared Sub Main()

      ' Creates and initializes a one-dimensional array. 
      Dim myArr1(4) As [String]

      ' Sets the element at index 3.
      myArr1.SetValue("three", 3)
      Console.WriteLine("[3]:   {0}", myArr1.GetValue(3))


      ' Creates and initializes a two-dimensional array. 
      Dim myArr2(5, 5) As [String]

      ' Sets the element at index 1,3.
      myArr2.SetValue("one-three", 1, 3)
      Console.WriteLine("[1,3]:   {0}", myArr2.GetValue(1, 3))


      ' Creates and initializes a three-dimensional array. 
      Dim myArr3(5, 5, 5) As [String]

      ' Sets the element at index 1,2,3.
      myArr3.SetValue("one-two-three", 1, 2, 3)
      Console.WriteLine("[1,2,3]:   {0}", myArr3.GetValue(1, 2, 3))


      ' Creates and initializes a seven-dimensional array. 
      Dim myArr7(5, 5, 5, 5, 5, 5, 5) As [String]

      ' Sets the element at index 1,2,3,0,1,2,3. 
      Dim myIndices() As Integer = {1, 2, 3, 0, 1, 2, 3}
      myArr7.SetValue("one-two-three-zero-one-two-three", myIndices)
      Console.WriteLine("[1,2,3,0,1,2,3]:   {0}", myArr7.GetValue(myIndices))

   End Sub 'Main 

End Class 'SamplesArray


'This code produces the following output. 

'[3]:   three 
'[1,3]:   one-three 
'[1,2,3]:   one-two-three 
'[1,2,3,0,1,2,3]:   one-two-three-zero-one-two-three
