Array.GetValue Method (Int32())

[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]

Gets the value at the specified position in the multidimensional Array. The indexes are specified as an array of 32-bit integers.

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

'Declaration
Public Function GetValue ( _
	ParamArray indices As Integer() _
) As Object

Parameters

indices
Type: System.Int32 ()
A one-dimensional array of 32-bit integers that represent the indexes specifying the position of the Array element to get.

Return Value

Type: System.Object
The value at the specified position in the multidimensional Array.

ExceptionCondition
ArgumentNullException

indices is Nothing.

ArgumentException

The number of dimensions in the current Array is not equal to the number of elements in indices.

IndexOutOfRangeException

Any element in indices is outside the range of valid indexes for the corresponding dimension of the current Array.

The number of elements in indices must equal the number of dimensions in the Array. All elements in the indices array must collectively specify the position of the desired element in the multidimensional 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.



Public Class Example

   Public Shared Sub Demo(ByVal outputBlock As System.Windows.Controls.TextBlock)

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

      ' Sets the element at index 3.
      myArr1.SetValue("three", 3)
      outputBlock.Text += String.Format("[3]:   {0}", myArr1.GetValue(3)) & vbCrLf


      ' 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)
      outputBlock.Text += String.Format("[1,3]:   {0}", myArr2.GetValue(1, 3)) & vbCrLf


      ' 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)
      outputBlock.Text += String.Format("[1,2,3]:   {0}", myArr3.GetValue(1, 2, 3)) & vbCrLf


      ' 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)
      outputBlock.Text += String.Format("[1,2,3,0,1,2,3]:   {0}", myArr7.GetValue(myIndices)) & vbCrLf

   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
