怎样提高WebService的性能 服务器端WebService程序 using System.Runtime.Serialization.Formatters.Binary; using System.IO; using System.IO.Compression; using System.Data.SqlClient; ……… public class Service1 : System.Web.Services.WebService { [WebMethod(Description = 直接返回 DataSet 对象。)] public DataSet GetNorthwindDataSet() { string sql = SELECT * FROM XT_TEXT; SqlConnection conn = new SqlConnection(Server=8;DataBase=s168593;user id=s168593;password=h0y+FeC*;); conn.Open(); SqlDataAdapter dataadapter = new SqlDataAdapter(sql, conn); DataSet ds = new DataSet(); dataadapter.Fill(ds, XT_TEXT); conn.Close(); return ds; } [WebMethod(Description = 返回 DataSet 对象用 Binary 序列化后的字节数组。)] public byte[] GetDataSetBytes() { DataSet dataSet = GetNorthwindDataSet(); BinaryFormatter ser = new BinaryFormatter(); MemoryStream ms = new MemoryStream(); ser.Serialize(ms, dataSet); byte[] buffer = ms.ToArray(); return buffer; } [WebMethod(Description = 返回 DataSetSurrogate 对象用 Binary 序列化后的字节数组。)] public byte[] GetDataSetSurrogateBytes() { DataSet dataSet = GetNorthwindDataSet(); DataSetSurrogate dss = new DataSetSurrogate(dataSet); BinaryFormatter ser = new BinaryFormatter(); MemoryStream ms = new MemoryStream(); ser.Serialize(ms, dss); byte[] buffer = ms.ToArray(); return buffer; } [WebMethod(Description = 返回 DataSetSurrogate 对象用 Binary 序列化并 Zip 压缩后的字节数组。)] public byte[] GetDataSetSurrogateZipBytes() { DataSet dataSet = GetNorthwindDataSet(); DataSetSurrogate dss = new DataSetSurrogate(dataSet); BinaryFormatter ser = new BinaryFormatter(); MemoryStream ms = new MemoryStream(); ser.Serialize(ms, dss); byte[] buffer = ms.ToArray(); byte[] zipBuffer = Compress(buffer); return zipBuffer; } public byte[] Compress(byte[] data)
