ASP.NET连接数据库

连接Access:

OleDbConnection conn = new OleDbConnection();
conn.ConnectionString = "provider=microsoft.jet.oledb.4.0;data source=绝对路径";//+Server.MapPath("相对路径");

连接SqlServer

SqlConnection conn1 = new SqlConnection();
conn1.ConnectionString = "Data Source=服务器名;uid=用户名;pwd=密码;database=数据库名;integrated security=true";

conn.Open();//开启连接
conn.Close();//关闭连接

操作数据库

OleDbCommand comm = new OleDbCommand();
comm.CommandText = "数据库操作命今";
comm.Connection = conn;
comm.ExecuteNonQuery();
