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：

1. using System.IO;
2. using System.Net;
3. using System;
4. namespace Framework
5. {
6. public class NetStream
7. {
8. private MemoryStream stream;
9. private BinaryReader reader;
10. private BinaryWriter writer;
11. public NetStream(byte[] buffer = null)
12. {
13. if (buffer == null)
14. {
15. this.stream = new MemoryStream();
16. }
17. else
18. {
19. this.stream = new MemoryStream(buffer);
20. }
21. this.reader = new BinaryReader(this.stream);
22. this.writer = new BinaryWriter(this.stream);
23. }
24. public void Close()
25. {
26. this.stream.Close();
27. this.reader.Close();
28. this.writer.Close();
29. }
30. public long ReadInt64()
31. {
32. return IPAddress.HostToNetworkOrder(this.reader.ReadInt64());
33. }
34. public int ReadInt32()
35. {
36. return IPAddress.HostToNetworkOrder(this.reader.ReadInt32());
37. }
38. public int ReadInt16()
39. {
40. return IPAddress.HostToNetworkOrder(this.reader.ReadInt16());
41. }
42. public byte ReadByte()
43. {
44. return this.reader.ReadByte();
45. }
46. public string ReadString8()
47. {
48. return System.Text.Encoding.UTF8.GetString
49. (
50. this.reader.ReadBytes(ReadByte())
51. );
52. }
53. public string ReadString16()
54. {
55. return System.Text.Encoding.UTF8.GetString
56. (
57. this.reader.ReadBytes(ReadInt16())
58. );
59. }
60. public long Seek(long offset)
61. {
62. return this.stream.Seek(offset, SeekOrigin.Begin);
63. }
64. // -------------------------------------------------------------------------------
65. public void WriteByte(byte value)
66. {
67. this.writer.Write(value);
68. }
69. public void WriteInt16(short value)
70. {
71. this.writer.Write
72. (
73. BitConverter.GetBytes
74. (
75. IPAddress.HostToNetworkOrder(value)
76. )
77. );
78. }
79. public void WriteInt32(int value)
80. {
81. this.writer.Write
82. (
83. BitConverter.GetBytes
84. (
85. IPAddress.HostToNetworkOrder(value)
86. )
87. );
88. }
89. public void WriteInt64(long value)
90. {
91. this.writer.Write
92. (
93. BitConverter.GetBytes
94. (
95. IPAddress.HostToNetworkOrder(value)
96. )
97. );
98. }
99. public void WriteString8(string value)
100. {
101. WriteByte
102. (
103. (byte) value.Length
104. );
105. this.writer.Write
106. (
107. System.Text.Encoding.UTF8.GetBytes(value)
108. );
109. }
110. public void WriteString16(string value)
111. {
112. WriteInt16
113. (
114. (short) value.Length
115. );
116. this.writer.Write
117. (
118. System.Text.Encoding.UTF8.GetBytes(value)
119. );
120. }
121. public byte[] GetBuffer()
122. {
123. return this.stream.ToArray();
124. }
125. public int GetLength()
126. {
127. return (int) this.stream.Length;
128. }
129. }
130. }
