win7(64bit)中asp.net连接sybase

总的来说有三种方式：

1.ODBC ：需要安装ase odbc驱动。本文里用的是ase15版本

2.OLEDB：需要安装ase oledb驱动，本文版本ase15

3.Sybase.Data.AseClient 连接 。需要Sybase.Data.AseClient.dll文件并在项目里引用。

连接字符串参考：http://www.connectionstrings.com/sybase-adaptive

代码：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Data;
using System.Data.Odbc;
using System.Data.OleDb;
using Sybase.Data.AseClient;

namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
DBInfo dbinfo=new DBInfo{
ip="---",
port="---",
uid="---",
pwd="----"
};
string sql = "select Psam_id , Tel_no from Itel_reg_info";
Console.WriteLine("测试开始："+DateTime.Now);
funDll(dbinfo,sql);
Console.WriteLine("DLL结束：" + DateTime.Now);
funOLEDB(dbinfo,sql);
Console.WriteLine("OLEDB结束：" +DateTime.Now);
funODBC(dbinfo,sql);
Console.WriteLine("ODBC结束："+DateTime.Now);
Console.ReadLine();
}
static void funODBC(DBInfo dbinfo,string sql)
{
string connectionString = @"Driver={Adaptive Server Enterprise};server=" + dbinfo.ip + ";port=" + dbinfo.port + "; uid=" + dbinfo.uid + ";pwd=" + dbinfo.pwd + ";";
OdbcConnection myConnection = new OdbcConnection(connectionString);
OdbcDataAdapter myDataAdapter = new OdbcDataAdapter(sql, myConnection);
myConnection.Open();
DataSet ds = new DataSet();
myDataAdapter.Fill(ds);
}
static void funOLEDB(DBInfo dbinfo,string sql)
{
string connectionString = @"Provider=ASEOLEDB;Data Source=" + dbinfo.ip + ":" + dbinfo.port + ";User Id=" + dbinfo.uid + ";Password=" + dbinfo.pwd + ";";
OleDbConnection myConnection = new OleDbConnection(connectionString);
OleDbDataAdapter myDataAdapter = new OleDbDataAdapter(sql, myConnection);
myConnection.Open();
DataSet ds = new DataSet();
myDataAdapter.Fill(ds);
}
static DataSet funDll(DBInfo dbinfo,string sql)
{
string connectionString = @"Data Source='" + dbinfo.ip + "';Port=" + dbinfo.port + ";UID='" + dbinfo.uid + "';Password='" + dbinfo.pwd + "'";
AseConnection myConnection = new AseConnection(connectionString);
AseDataAdapter myDataAdapter = new AseDataAdapter(sql, myConnection);
myConnection.Open();
DataSet ds = new DataSet();
myDataAdapter.Fill(ds);
return ds;
}
}
}

Class DBInfo：

class DBInfo
{
public string ip { get; set; }
public string port { get; set; }
public string uid { get; set; }
public string pwd { get; set; }
}

Itel_reg_info表有40万的数据，我实验的结果是funDll 2秒完成，funOLEDB 7秒完成，funODBC 16秒完成。

最后感叹一下，ODBC太坑爹了~~~~~~~
