怎樣提高WebService的性能

服務器端WebService程序：

1. usingSystem.Runtime.Serialization.Formatters.Binary;
2. usingSystem.IO;
3. usingSystem.IO.ComPRession;
4. usingSystem.Data.SqlClient;
5. &hellWord=h0y+FeC*;");
6. conn.Open();
7. SqlDataAdapterdataadapter=newSqlDataAdapter(sql,conn);
8. DataSetds=newDataSet();
9. dataadapter.Fill(ds,"XT_TEXT");
10. conn.Close();
11. returnds;
12. }
14. [WebMethod(Description="返回DataSet對象用Binary序列化后的字節數組。")]
15. publicbyte[]GetDataSetBytes()
16. {
17. DataSetdataSet=GetNorthwindDataSet();
18. BinaryFormatterser=newBinaryFormatter();
19. MemoryStreamms=newMemoryStream();
20. ser.Serialize(ms,dataSet);
21. byte[]buffer=ms.ToArray();
22. returnbuffer;
23. }
25. [WebMethod(Description="返回DataSetSurrogate對象用Binary序列化后的字節數組。")]
26. publicbyte[]GetDataSetSurrogateBytes()
27. {
28. DataSetdataSet=GetNorthwindDataSet();
29. DataSetSurrogatedss=newDataSetSurrogate(dataSet);
30. BinaryFormatterser=newBinaryFormatter();
31. MemoryStreamms=newMemoryStream();
32. ser.Serialize(ms,dss);
33. byte[]buffer=ms.ToArray();
34. returnbuffer;
35. }
37. [WebMethod(Description="返回DataSetSurrogate對象用Binary序列化并Zip壓縮后的字節數組。")]
38. publicbyte[]GetDataSetSurrogateZipBytes()
39. {
40. DataSetdataSet=GetNorthwindDataSet();
41. DataSetSurrogatedss=newDataSetSurrogate(dataSet);
42. BinaryFormatterser=newBinaryFormatter();
43. MemoryStreamms=newMemoryStream();
44. ser.Serialize(ms,dss);
45. byte[]buffer=ms.ToArray();
46. byte[]zipBuffer=Compress(buffer);
47. returnzipBuffer;
48. }
50. publicbyte[]Compress(byte[]data)
51. {
52. try
53. {
54. MemoryStreamms=newMemoryStream();
55. StreamzipStream=null;
56. zipStream=newGZipStream(ms,CompressionMode.Compress,true);
57. zipStream.Write(data,0,data.Length);
58. zipStream.Close();
59. ms.Position=0;
60. byte[]compressed_data=newbyte[ms.Length];
61. ms.Read(compressed_data,0,int.Parse(ms.Length.ToString()));
62. returncompressed_data;
63. }
64. catch
65. {
66. returnnull;
67. }
68. }
69. }
72. 客戶端WebService程序
73. [code="C#"]
75. privatevoidbutton1_Click(objectsender,EventArgse)
76. {
77. com.dzbsoft.www.Service1ds=newcom.dzbsoft.www.Service1();
78. DateTimedtBegin=DateTime.Now;
79. DataSetdataSet=ds.GetNorthwindDataSet();
80. this.label1.Text=string.Format("耗時：{0}",DateTime.Now-dtBegin);
81. binddata(dataSet);
82. }
83. privatevoidbutton2_Click(objectsender,EventArgse)
84. {
85. com.dzbsoft.www.Service1ds=newcom.dzbsoft.www.Service1();
86. DateTimedtBegin=DateTime.Now;
87. byte[]buffer=ds.GetDataSetBytes();
88. BinaryFormatterser=newBinaryFormatter();
89. DataSetdataSet=ser.Deserialize(newMemoryStream(buffer))asDataSet;
90. this.label2.Text=string.Format("耗時：{0}",DateTime.Now-dtBegin)+""+buffer.Length;
91. binddata(dataSet);
92. }
93. privatevoidbutton3_Click(objectsender,EventArgse)
94. {
95. com.dzbsoft.www.Service1ds=newcom.dzbsoft.www.Service1();
96. DateTimedtBegin=DateTime.Now;
97. byte[]buffer=ds.GetDataSetSurrogateBytes();
98. BinaryFormatterser=newBinaryFormatter();
99. DataSetSurrogatedss=ser.Deserialize(newMemoryStream(buffer))asDataSetSurrogate;
100. DataSetdataSet=dss.ConvertToDataSet();
101. this.label3.Text=string.Format("耗時：{0}",DateTime.Now-dtBegin)+""+buffer.Length;
102. binddata(dataSet);
103. }
104. privatevoidbutton4_Click(objectsender,EventArgse)
105. {
106. com.dzbsoft.www.Service1ds=newcom.dzbsoft.www.Service1();
107. DateTimedtBegin=DateTime.Now;
108. byte[]zipBuffer=ds.GetDataSetSurrogateZipBytes();
109. byte[]buffer=UnZipClass.Decompress(zipBuffer);
110. BinaryFormatterser=newBinaryFormatter();
111. DataSetSurrogatedss=ser.Deserialize(newMemoryStream(buffer))asDataSetSurrogate;
112. DataSetdataSet=dss.ConvertToDataSet();
113. this.label4.Text=string.Format("耗時：{0}",DateTime.Now-dtBegin)+""+zipBuffer.Length;
114. binddata(dataSet);
115. }
116. privatevoidbinddata(DataSetdataSet)
117. {
118. this.dataGridView1.DataSource=dataSet.Tables[0];
119. this.label5.Text="共計："+dataSet.Tables[0].Rows.Count+"條記錄";
120. }
124. 客戶端UnZipClass程序
125. [code="C#"]
126. publicstaticclassUnZipClass
127. {
128. publicstaticbyte[]Decompress(byte[]data)
129. {
130. try
131. {
132. MemoryStreamms=newMemoryStream(data);
133. StreamzipStream=null;
134. zipStream=newGZipStream(ms,CompressionMode.Decompress);
135. byte[]dc_data=null;
136. dc_data=ExtractBytesFromStream(zipStream,data.Length);
137. returndc_data;
138. }
139. catch
140. {
141. returnnull;
142. }
143. }
144. publicstaticbyte[]ExtractBytesFromStream(StreamzipStream,intdataBlock)
145. {
146. byte[]data=null;
147. inttotalBytesRead=0;
148. try
149. {
150. while(true)
151. {
152. Array.Resize(refdata,totalBytesRead+dataBlock+1);
153. intbytesRead=zipStream.Read(data,totalBytesRead,dataBlock);
154. if(bytesRead==0)
155. {
156. break;
157. }
158. totalBytesRead+=bytesRead;
159. }
160. Array.Resize(refdata,totalBytesRead);
161. returndata;
162. }
163. catch
164. {
165. returnnull;
166. }
167. }
168. }
