Array.SetValue Método (Object, Int64, Int64, Int64)

Sets a value to the element at the specified position in the three-dimensional Array.Os índices são especificados como números inteiros de 64 bits.

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

[ComVisibleAttribute(false)]
public void SetValue(
	Object value,
	long index1,
	long index2,
	long index3
)

Parâmetros

value
Tipo: System.Object
O novo valor para o elemento especificado.
index1
Tipo: System.Int64
A 64-bit integer that represents the first-dimension index of the Array element to set.
index2
Tipo: System.Int64
A 64-bit integer that represents the second-dimension index of the Array element to set.
index3
Tipo: System.Int64
A 64-bit integer that represents the third-dimension index of the Array element to set.

ExceçãoCondição
ArgumentException

The current Array does not have exactly three dimensions.

InvalidCastException

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

ArgumentOutOfRangeException

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.

Este método é uma operação O(1).

ObservaçãoObservação:

If SetValue is used to assign null to an element of an array of value types, all fields of the element are initialized to zero.The valor of the elemento is not a NULL Reference, and cannot be found by searching for a NULL Reference.

O exemplo de código a seguir demonstra como configurar e obter um valor específico em uma matriz unidimensional ou multidimensional.

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 ) );

   }

}
