Ejemplos

En el ejemplo de código siguiente se convierten los elementos de las matrices Byte a valores UInt16 con el método ToUInt16.The following code example converts elements of Byte arrays to UInt16 values with the ToUInt16 method.

// Example of the BitConverter::ToUInt16 method.
using namespace System;

// Convert two byte array elements to an unsigned short and display it.
void BAToUInt16( array<unsigned char>^bytes, int index )
{
   unsigned short value = BitConverter::ToUInt16( bytes, index );
   Console::WriteLine( "{0,5}{1,17}{2,16}", index, BitConverter::ToString( bytes, index, 2 ), value );
}

int main()
{
   array<unsigned char>^byteArray = {15,0,0,255,3,16,39,255,255,127};
   Console::WriteLine( "This example of the BitConverter::ToUInt16( unsigned "
   "char[ ], int ) \nmethod generates the following output. It "
   "converts elements of a \nbyte array to unsigned short "
   "values.\n" );
   Console::WriteLine( "initial byte array" );
   Console::WriteLine( "------------------" );
   Console::WriteLine( BitConverter::ToString( byteArray ) );
   Console::WriteLine();
   Console::WriteLine( "{0,5}{1,17}{2,16}", "index", "array elements", "unsigned short" );
   Console::WriteLine( "{0,5}{1,17}{2,16}", "-----", "--------------", "--------------" );
   
   // Convert byte array elements to unsigned short values.
   BAToUInt16( byteArray, 1 );
   BAToUInt16( byteArray, 0 );
   BAToUInt16( byteArray, 3 );
   BAToUInt16( byteArray, 5 );
   BAToUInt16( byteArray, 8 );

El método ToUInt16 convierte los bytes del índice startIndex a startIndex + 1 a un valor UInt16.The ToUInt16 method converts the bytes from index startIndex to startIndex + 1 to a UInt16 value. El orden de los bytes de la matriz debe reflejar el modos endian de la arquitectura del sistema del equipo; para obtener más información, vea la sección Comentarios del tema de la clase BitConverter.The order of bytes in the array must reflect the endianness of the computer system's architecture; for more information, see the Remarks section of the BitConverter class topic.
