1.1.2 ADO.NET模型

源代码：13033480群共享

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 @R_968_4045@ion = "WestGarden.Data.sqlClient.sqlConnection";
        }
        public class sqlCommand
        {
            public string @R_968_4045@ion = "WestGarden.Data.sqlClient.sqlCommand";
        }
        public class sqlDataReader
        {
            public string @R_968_4045@ion = "WestGarden.Data.sqlClient.sqlDataReader";
        }
        public class sqlDataAdapter
        {
            public string @R_968_4045@ion = "WestGarden.Data.sqlClient.sqlDataAdapter";
        }
    }

    namespace OleDb
    {
        public class OleDbConnection
        {
            public string @R_968_4045@ion = "WestGarden.Data.OleDb.OleDbConnection";
        }
        public class OleDbCommand
        {
            public string @R_968_4045@ion = "WestGarden.Data.OleDb.OleDbCommand";
        }
        public class OleDbDataReader
        {
            public string @R_968_4045@ion = "WestGarden.Data.OleDb.OleDbDataReader";
        }
        public class OleDbDataAdapter
        {
            public string @R_968_4045@ion = "WestGarden.Data.OleDb.OleDbDataAdapter";
        }
    }
    
    namespace Odbc
    {
        public class OdbcConnection
        {
            public string @R_968_4045@ion = "WestGarden.Data.Odbc.OdbcConnection";
        }
        public class OdbcCommand
        {
            public string @R_968_4045@ion = "WestGarden.Data.Odbc.OdbcCommand";
        }
        public class OdbcDataReader
        {
            public string @R_968_4045@ion = "WestGarden.Data.Odbc.OdbcDataReader";
        }
        public class OdbcDataAdapter
        {
            public string @R_968_4045@ion = "WestGarden.Data.Odbc.OdbcDataAdapter";
        }
    }
   
    namespace OracleClient
    {
        public class OracleConnection
        {
            public string @R_968_4045@ion = "WestGarden.Data.OracleClient.OracleConnection";
        }
        public class OracleCommand
        {
            public string @R_968_4045@ion = "WestGarden.Data.OracleClient.OracleCommand";
        }
        public class OracleDataReader
        {
            public string @R_968_4045@ion = "WestGarden.Data.OracleClient.OracleDataReader";
        }
        public class OracleDataAdapter
        {
            public string @R_968_4045@ion = "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.@R_968_4045@ion + "</br>");

            Response.Write(cmd.@R_968_4045@ion + "</br>");

            Response.Write(rdr.@R_968_4045@ion + "</br>");

            Response.Write(da.@R_968_4045@ion + "</br></br>");

        }

        void OleDb()

        {

            OleDbConnection conn = new OleDbConnection();

            OleDbCommand cmd = new OleDbCommand();

            OleDbDataReader rdr = new OleDbDataReader();

            OleDbDataAdapter da = new OleDbDataAdapter();

 

            Response.Write(conn.@R_968_4045@ion + "</br>");

            Response.Write(cmd.@R_968_4045@ion + "</br>");

            Response.Write(rdr.@R_968_4045@ion + "</br>");

            Response.Write(da.@R_968_4045@ion + "</br></br>");

        }

        void Odbc()

        {

            OdbcConnection conn = new OdbcConnection();

            OdbcCommand cmd = new OdbcCommand();

            OdbcDataReader rdr = new OdbcDataReader();

            OdbcDataAdapter da = new OdbcDataAdapter();

 

            Response.Write(conn.@R_968_4045@ion + "</br>");

            Response.Write(cmd.@R_968_4045@ion + "</br>");

            Response.Write(rdr.@R_968_4045@ion + "</br>");

            Response.Write(da.@R_968_4045@ion + "</br></br>");

        }

 

        void Oracle()

        {

            OracleConnection conn = new OracleConnection();

            OracleCommand cmd = new OracleCommand();

            OracleDataReader rdr = new OracleDataReader();

            OracleDataAdapter da = new OracleDataAdapter();

 

            Response.Write(conn.@R_968_4045@ion + "</br>");

            Response.Write(cmd.@R_968_4045@ion + "</br>");

            Response.Write(rdr.@R_968_4045@ion + "</br>");

            Response.Write(da.@R_968_4045@ion + "</br></br>");

        }

    }

}
