Array.GetValue Method (Int64, Int64)
.NET Framework (current version)
Gets the value at the specified position in the two-dimensional Array. The indexes are specified as 64-bit integers.
Assembly: mscorlib (in mscorlib.dll)
<ComVisibleAttribute(False)> Public Function GetValue ( index1 As Long, index2 As Long ) As Object
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.
| Exception | Condition |
|---|---|
| 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
