Array.GetValue Method (Int32)

Gets the value at the specified position in the one-dimensional Array. The index is specified as a 32-bit integer.

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

public Object GetValue (
	int index
)
public Object GetValue (
	int index
)
public function GetValue (
	index : int
) : Object

Parameters

index

A 32-bit integer that represents the position of the Array element to get.

Return Value

The value at the specified position in the one-dimensional Array.

Exception typeCondition

ArgumentException

The current Array does not have exactly one dimension.

IndexOutOfRangeException

index is outside the range of valid indexes for the current Array.

The GetLowerBound and GetUpperBound methods can determine whether the value of index 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.

using System;

public class SamplesArray  {

   public static void Main()  {
 
      // Creates and initializes a one-dimensional array.
      String[] myArr1 = new String[5];

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


      // Creates and initializes a two-dimensional array.
      String[,] myArr2 = new String[5,5];

      // 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.
      String[,,] myArr3 = new String[5,5,5];

      // 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.
      String[,,,,,,] myArr7 = new String[5,5,5,5,5,5,5];

      // Sets the element at index 1,2,3,0,1,2,3.
      int[] myIndices = new int[7] { 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 ) );

   }
 
}
