En el ejemplo de código siguiente se muestra cómo leer Double y escribir datos en la memoria BinaryReader mediante BinaryWriter las clases y en la MemoryStream parte superior de la clase.The following code example shows how to read and write Double data to memory by using the BinaryReader and BinaryWriter classes on top of the MemoryStream class.

using namespace System;
using namespace System::IO;
int main()
{
   int i;
   const int arrayLength = 1000;
   
   // Create random data to write to the stream.
   array<double>^dataArray = gcnew array<double>(arrayLength);
   Random^ randomGenerator = gcnew Random;
   for ( i = 0; i < arrayLength; i++ )
   {
      dataArray[ i ] = 100.1 * randomGenerator->NextDouble();

   }
   BinaryWriter^ binWriter = gcnew BinaryWriter( gcnew MemoryStream );
   try
   {
      
      // Write data to the stream.
      Console::WriteLine( "Writing data to the stream." );
      i = 0;
      for ( i = 0; i < arrayLength; i++ )
      {
         binWriter->Write( dataArray[ i ] );
