Im folgenden Codebeispiel wird veranschaulicht, wie Double-Daten mithilfe der BinaryReader-Klasse und der BinaryWriter-Klasse in Zusammenarbeit mit der MemoryStream-Klasse im Arbeitsspeicher gelesen und geschrieben werden.
using System; using System.IO; class BinaryRW { static void Main() { int i; const int arrayLength = 1000; // Create random data to write to the stream. Random randomGenerator = new Random(); double[] dataArray = new double[arrayLength]; for(i = 0; i < arrayLength; i++) { dataArray[i] = 100.1 * randomGenerator.NextDouble(); } using(BinaryWriter binWriter = new BinaryWriter(new MemoryStream())) { // Write the data to the stream. Console.WriteLine("Writing data to the stream."); for(i = 0; i < arrayLength; i++) { binWriter.Write(dataArray[i]); } // Create a reader using the stream from the writer. using(BinaryReader binReader = new BinaryReader(binWriter.BaseStream)) { try { // Return to the beginning of the stream. binReader.BaseStream.Position = 0; // Read and verify the data. Console.WriteLine("Verifying the written data."); for(i = 0; i < arrayLength; i++) { if(binReader.ReadDouble() != dataArray[i]) { Console.WriteLine("Error writing data."); break; } } Console.WriteLine("The data was written " + "and verified."); } catch(EndOfStreamException e) { Console.WriteLine("Error writing data: {0}.", e.GetType().Name); } } } } }
