一、新建解决方案MyADOdotNET。
二、在解决方案中添加类库项目Data，设置属性。
三、在类库Data中添加类Data.cs。
四、在Data.cs中添加代码：
namespace WestGarden.Data
{
namespace SqlClient
{
public class SqlConnection
{
public string Information = "WestGarden.Data.SqlClient.SqlConnection";
}
public class SqlCommand
{
public string Information = "WestGarden.Data.SqlClient.SqlCommand";
}
public class SqlDataReader
{
public string Information = "WestGarden.Data.SqlClient.SqlDataReader";
}
public class SqlDataAdapter
{
public string Information = "WestGarden.Data.SqlClient.SqlDataAdapter";
}
}
namespace OleDb
{
public class OleDbConnection
{
public string Information = "WestGarden.Data.OleDb.OleDbConnection";
}
public class OleDbCommand
{
public string Information = "WestGarden.Data.OleDb.OleDbCommand";
}
public class OleDbDataReader
{
public string Information = "WestGarden.Data.OleDb.OleDbDataReader";
}
public class OleDbDataAdapter
{
public string Information = "WestGarden.Data.OleDb.OleDbDataAdapter";
}
}
namespace Odbc
{
public class OdbcConnection
{
public string Information = "WestGarden.Data.Odbc.OdbcConnection";
}
public class OdbcCommand
{
public string Information = "WestGarden.Data.Odbc.OdbcCommand";
}
public class OdbcDataReader
{
public string Information = "WestGarden.Data.Odbc.OdbcDataReader";
}
public class OdbcDataAdapter
{
public string Information = "WestGarden.Data.Odbc.OdbcDataAdapter";
}
}
namespace OracleClient
{
public class OracleConnection
{
public string Information = "WestGarden.Data.OracleClient.OracleConnection";
}
public class OracleCommand
{
public string Information = "WestGarden.Data.OracleClient.OracleCommand";
}
public class OracleDataReader
{
public string Information = "WestGarden.Data.OracleClient.OracleDataReader";
}
public class OracleDataAdapter
{
public string Information = "WestGarden.Data.OracleClient.OracleDataAdapter";
}
}
}
五、在解决方案中添加网站项目Web。
六、在Default.aspx.cs中添加代码：
using System;
using WestGarden.Data.SqlClient;
using WestGarden.Data.OleDb;
using WestGarden.Data.Odbc;
using WestGarden.Data.OracleClient;
namespace WestGarden.Web
{
public partial class Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
Response.Write("SQLServer.NET数据提供程序核心类有4个，分别是：</br>");
SQLServer();
Response.Write("OleDb.NET数据提供程序核心类有4个，分别是：</br>");
OleDb();
Response.Write("Odbc.NET数据提供程序核心类有4个，分别是：</br>");
Odbc();
Response.Write("Oracle.NET数据提供程序核心类有4个，分别是：</br>");
Oracle();
}
void SQLServer()
{
SqlConnection conn = new SqlConnection();
SqlCommand cmd = new SqlCommand();
SqlDataReader rdr = new SqlDataReader();
SqlDataAdapter da = new SqlDataAdapter();
Response.Write(conn.Information + "</br>");
Response.Write(cmd.Information + "</br>");
Response.Write(rdr.Information + "</br>");
Response.Write(da.Information + "</br></br>");
}
void OleDb()
{
OleDbConnection conn =new OleDbConnection();
OleDbCommand cmd = new OleDbCommand();
OleDbDataReader rdr =new OleDbDataReader();
OleDbDataAdapter da =new OleDbDataAdapter();
Response.Write(conn.Information + "</br>");
Response.Write(cmd.Information + "</br>");
Response.Write(rdr.Information + "</br>");
Response.Write(da.Information + "</br></br>");
}
void Odbc()
{
OdbcConnection conn =new OdbcConnection();
OdbcCommand cmd = new OdbcCommand();
OdbcDataReader rdr = new OdbcDataReader();
OdbcDataAdapter da = new OdbcDataAdapter();
Response.Write(conn.Information + "</br>");
Response.Write(cmd.Information + "</br>");
Response.Write(rdr.Information + "</br>");
Response.Write(da.Information + "</br></br>");
}
void Oracle()
{
OracleConnection conn =new OracleConnection();
OracleCommand cmd = new OracleCommand();
OracleDataReader rdr =new OracleDataReader();
OracleDataAdapter da =new OracleDataAdapter();
Response.Write(conn.Information + "</br>");
Response.Write(cmd.Information + "</br>");
Response.Write(rdr.Information + "</br>");
Response.Write(da.Information + "</br></br>");
}
}
}
