예제

다음 코드 예제에는 읽기 및 쓰기는 방법을 보여 줍니다 Double 를 사용 하 여 메모리 데이터를 BinaryReaderBinaryWriter 의 맨 위에 있는 클래스는 MemoryStream 클래스.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. MemoryStream 읽기 및 쓰기만 Byte 데이터입니다.MemoryStream only reads and writes Byte data.

   Random^ randomGenerator = gcnew Random;
   for ( i = 0; i < arrayLength; i++ )
   {
      dataArray[ i ] = 100.1 * randomGenerator->NextDouble();

   }
   BinaryWriter^ binWriter = gcnew BinaryWriter( gcnew MemoryStream );
   try
   {
