主要代码如下:
//连接字符串 string strConn="user id=sa;password=123456;initial catalog=MyDb;Server=192.168.47.144,1433;Connect Timeout=10";
//创建连接对象
SqlConnection objConn = new SqlConnection(strConn); try
{ //开始连接数据库
objConn.Open();
//执行SQL语句
string sql = "SELECT * FROM tb_People";
SqlCommand sqlCom = new SqlCommand(sql,objConn);
//创建数据读取器对象,注意:该对象只能顺序读取记录
SqlDataReader sqlDataReader = sqlCom.ExecuteReader();
//循环输出记录
int i = 1;
while(sqlDataReader.Read()){ Console.WriteLine("\n表tb_People第{0}条记录为:{1}{2}",
i,
sqlDataReader.GetValue(0),
sqlDataReader.GetValue(1));
i++;
}
//断开与数据库的连接...
objConn.Close();
}
//捕获异常...
catch(SqlException e){ objConn.Close();
Console.WriteLine(e.Message+e.ErrorCode);
}
