Esempio

Nell'esempio seguente gli schemi di bit dei valori vengono convertiti Boolean in Byte matrici con il GetBytes metodo.The following example converts the bit patterns of Boolean values to Byte arrays with the GetBytes method.

using namespace System;

int main()
{
    // Define Boolean true and false values.
    array<bool>^ values = { true, false };

    // Display the value and its corresponding byte array.
    Console::WriteLine("{0,10}{1,16}\n", "Boolean", "Bytes");
    for each (Byte value in values) {
       array<Byte>^ bytes = BitConverter::GetBytes(value); 
       Console::WriteLine("{0,10}{1,16}", value, 
                          BitConverter::ToString(bytes));
    }
}
// This example displays the following output:
//        Boolean           Bytes
//     
//           True              01
//          False              00

using System;

class Example
{
   public static void Main( )
   {
      // Define Boolean true and false values.
      bool[] values = { true, false };

      // Display the value and its corresponding byte array.
      Console.WriteLine("{0,10}{1,16}\n", "Boolean", "Bytes");
      foreach (var value in values) {
         byte[] bytes = BitConverter.GetBytes(value);
         Console.WriteLine("{0,10}{1,16}", value,
                           BitConverter.ToString(bytes));
      }
   }
}
// The example displays the following output:
//        Boolean           Bytes
//
//           True              01
//          False              00

Module Example
   Public Sub Main()
      ' Define Boolean true and false values.
      Dim values() As Boolean = { true, false }

      ' Display the value and its corresponding byte array.
      Console.WriteLine("{0,10}{1,16}", "Boolean", "Bytes")
      Console.WriteLine()
      
      For Each value In values
         Dim bytes() As Byte = BitConverter.GetBytes(value) 
         Console.WriteLine("{0,10}{1,16}", value, 
                           BitConverter.ToString(bytes))
      Next
    End Sub

Commenti

L'ordine dei byte nella matrice restituita dal GetBytes metodo varia a seconda che l'architettura del computer sia little-endian o big-endian.The order of bytes in the array returned by the GetBytes method depends on whether the computer architecture is little-endian or big-endian.
