C#简单连接sql数据库的方法

本文实例讲述了C#简单连接sql数据库的方法。分享给大家供大家参考,具体如下:

?

using System;

using System.Collections.Generic;

using System.Text;

//数据库操作对象库

using System.Data;

using System.Data.SqlClient;

using worddic;

namespace testDB

{

   class Program

   {

     static void Main( string [] args)

     {

       //char[] array = new char[2] ;

       string [] a = new string [2];

       FileOp words = new FileOp();

       words.openfile( "worddic.txt" );

       words.getwords( ref a);

       /* Console.WriteLine("请输入Data Source:");

       string data_source = Console.ReadLine();

       Console.WriteLine("请输入Initial Catalog:");

       string initial_catalog = Console.ReadLine();

       Console.WriteLine("请输入user id:");

       string user_id = Console.ReadLine();

       Console.WriteLine("请输入pass word:");

       string pword = Console.ReadLine();

       //连接字符串

       string strConn ="Data Source="+data_source+";Initial Catalog="+initial_catalog+";User ID="+user_id+";Password="+pword+"";//YourPwd替换为你设置的sa账户密码

       */

       string strConn = "Data Source=HYPER-V-WIN2003\\SQLSRV2005;Initial Catalog=Mytest;User ID=sa;Password=sa" ;

       SqlConnection conn = null ;

       SqlCommand sqlCmd = null ;

       try

       {

         //创建connection对象

         conn = new SqlConnection(strConn);

         //打开数据库连接

         conn.Open();

         //创建Transac Sql命令对象

         sqlCmd = conn.CreateCommand();

         //创建建表语句

         //sqlCmd.CommandText = "create table wordlist(wrongwords varchar(30),rightwords varchar(30),sign char(20),)";

         //sqlCmd.ExecuteScalar();

         while (a[0] != null ) {

           sqlCmd.CommandText = "insert into wordlist(wrongwords,rightwords,sign) values('" + a[0] + "','" + a[1] + "',1 )" ;

           sqlCmd.ExecuteScalar();

           a[0] = null ;

           a[1] = null ;

           words.getwords( ref a);

         }

         words.fileclose();

         Console.WriteLine();

         //打印所有记录

       }

       catch (SqlException e)

       {

         Console.WriteLine(e.Message);

       }

       finally

       {

         conn.Close();

       }

       Console.WriteLine( "程序结束,按任意键退出" );

       Console.ReadKey();

     }

   }

}

希望本文所述对大家C#程序设计有所帮助。
