Array.GetValue Método

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

using namespace System;
int main()
{
   
   // Creates and initializes a one-dimensional array.
   array<String^>^myArr1 = gcnew array<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.
   array<String^, 2>^myArr2 = gcnew array<String^,2>(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.
   array<String^, 3>^myArr3 = gcnew array<String^,3>(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.
   array<String^, 7>^myArr7 = gcnew array<String^,7>(5,5,5,5,5,5,5);
   
   // Sets the element at index 1,2,3,0,1,2,3.
   array<Int32>^myIndices = {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 ) );
}
