网络数据是大端模式，而c#中的数据小端结构，那么在读写网络数据的时候需要进行转换。c#类库IPAddress已经封装了大小端的转换。

封装代码如下：

[csharp] view plain copy

using System.IO;
using System.Net;
using System;
namespace Framework
{
public class NetStream
{
private MemoryStream stream;
private BinaryReader reader;
private BinaryWriter writer;
public NetStream(byte[] buffer = null)
{
if (buffer == null)
{
this.stream = new MemoryStream();
}
else
{
this.stream = new MemoryStream(buffer);
}
this.reader = new BinaryReader(this.stream);
this.writer = new BinaryWriter(this.stream);
}
public void Close()
{
this.stream.Close();
this.reader.Close();
this.writer.Close();
}
public long ReadInt64()
{
return IPAddress.HostToNetworkOrder(this.reader.ReadInt64());
}
public int ReadInt32()
{
return IPAddress.HostToNetworkOrder(this.reader.ReadInt32());
}
public int ReadInt16()
{
return IPAddress.HostToNetworkOrder(this.reader.ReadInt16());
}
public byte ReadByte()
{
return this.reader.ReadByte();
}
public string ReadString8()
{
return System.Text.Encoding.UTF8.GetString
(
this.reader.ReadBytes(ReadByte())
);
}
public string ReadString16()
{
return System.Text.Encoding.UTF8.GetString
(
this.reader.ReadBytes(ReadInt16())
);
}
public long Seek(long offset)
{
return this.stream.Seek(offset, SeekOrigin.Begin);
}
// -------------------------------------------------------------------------------
public void WriteByte(byte value)
{
this.writer.Write(value);
}
public void WriteInt16(short value)
{
this.writer.Write
(
BitConverter.GetBytes
(
IPAddress.HostToNetworkOrder(value)
)
);
}
public void WriteInt32(int value)
{
this.writer.Write
(
BitConverter.GetBytes
(
IPAddress.HostToNetworkOrder(value)
)
);
}
public void WriteInt64(long value)
{
this.writer.Write
(
BitConverter.GetBytes
(
IPAddress.HostToNetworkOrder(value)
)
);
}
public void WriteString8(string value)
{
WriteByte
(
(byte) value.Length
);
this.writer.Write
(
System.Text.Encoding.UTF8.GetBytes(value)
);
}
public void WriteString16(string value)
{
WriteInt16
(
(short) value.Length
);
this.writer.Write
(
System.Text.Encoding.UTF8.GetBytes(value)
);
}
public byte[] GetBuffer()
{
return this.stream.ToArray();
}
public int GetLength()
{
return (int) this.stream.Length;
}
}
}
