C# Socket流数据大小端读写封装
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:
- 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;
- }
- }
- }
