Exempel

I följande kodexempel visas hur du läser och skriver Double data till minnet med hjälp BinaryReader av klasserna och BinaryWriter ovanpå MemoryStream klassen.

using System;
using System.IO;

class BinaryRW

        for(i = 0; i < arrayLength; i++)
        {
            dataArray[i] = 100.1 * randomGenerator.NextDouble();
        }
