Array.SetValue Method (Object, Int32, Int32, Int32)

Sets a value to the element at the specified position in the three-dimensional Array. The indexes are specified as 32-bit integers.

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

public void SetValue (
	Object value,
	int index1,
	int index2,
	int index3
)
public void SetValue (
	Object value, 
	int index1, 
	int index2, 
	int index3
)
public function SetValue (
	value : Object, 
	index1 : int, 
	index2 : int, 
	index3 : int
)
Not applicable.

Parameters

value

The new value for the specified element.

index1

A 32-bit integer that represents the first-dimension index of the Array element to set.

index2

A 32-bit integer that represents the second-dimension index of the Array element to set.

index3

A 32-bit integer that represents the third-dimension index of the Array element to set.

Exception typeCondition

ArgumentException

The current Array does not have exactly three dimensions.

InvalidCastException

value cannot be cast to the element type of the current Array.

IndexOutOfRangeException

index1 or index2 or index3 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.

For more information about conversions, see Convert.

This method is an O(1) operation.

NoteNote:

If SetValue is used to assign a null reference (Nothing in Visual Basic) to an element of an array of value types, all fields of the element are initialized to zero. The value of the element is not a null reference, and cannot be found by searching for a null reference.

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 ) );

   }
 
}
