Beispiele

Im folgenden Codebeispiel werden Elemente von Byte Arrays in UInt16 -Werte mit ToUInt16 der-Methode konvertiert.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 ) );

   BAToUInt16( byteArray, 1 );
   BAToUInt16( byteArray, 0 );
   BAToUInt16( byteArray, 3 );
   BAToUInt16( byteArray, 5 );

Hinweise

Die ToUInt16 -Methode konvertiert die Bytes vom startIndex Index startIndex in + 1 in UInt16 einen-Wert.The ToUInt16 method converts the bytes from index startIndex to startIndex + 1 to a UInt16 value. Die Reihenfolge der Bytes im Array muss die Byte Reihenfolge der Architektur des Computer Systems widerspiegeln. Weitere Informationen finden Sie im Abschnitt BitConverter "Hinweise" im Thema zur-Klasse.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.
