本文展示了如何使用C#的BinaryWriter和BinaryReader类在内存中进行二进制数据的读写操作，避免了文件作为中介。通过创建随机数据，将其写入MemoryStream，然后从同一个流中读取并验证数据，确保数据的正确性。

该程序通过使用BinaryWrite流的基类流BaseStream流来建立BinaryRead流通过MemoryStream内存流来写入和读出数据这样就不必保存在文件的中介了。

源代码如下：using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

using System.IO;
namespace BinaryStreamConsole
{
    class Program{
        static void Main(string[] args){
             const int arrayLength = 100;
            // Create random data to write to the stream.
            byte[] dataArray = new byte[arrayLength];
            new Random().NextBytes(dataArray);
            BinaryWriter binWriter = new BinaryWriter(new MemoryStream());
            // Write the data to the stream.
            Console.WriteLine("Writing the data.");
            binWriter.Write(dataArray, 0, arrayLength);
            // Create the reader using the stream from the writer.
            BinaryReader binReader =new BinaryReader(binWriter.BaseStream);
            // Set Position to the beginning of the stream.
            binReader.BaseStream.Position = 0;
            // Read and verify the data.
            byte[] verifyArray = new byte[arrayLength];
            if (binReader.Read(verifyArray, 0, arrayLength) != arrayLength){
                Console.WriteLine("Error writing the data.");
                return;
            }
            for (int i = 0; i < arrayLength; i++){
                if (verifyArray[i] != dataArray[i]){
                    Console.WriteLine("Error writing the data.");
                    return;
                }else{
                    Console.WriteLine(verifyArray[i].ToString());
                }
            }
            Console.WriteLine("The data was written and verified.");
            Console.ReadLine();
        }
    }
}
