ASP.net连接access数据库例程c#:
using System.Data.OleDb;
OleDbConnection myConnection;
OleDbCommand myCommand;
void page_load()
{
//1.连接数据库
string dbname;
dbname=Server.MapPath("authors.mdb");
myConnection = new OleDbConnection( "PROVIDER=Microsoft.Jet.OLEDB.4.0;DATA Source=" + dbname );
myConnection.Open();
la1.text="Connection Opened!";
//2.添加记录
myCommand = new OleDbCommand( "Insert INTO Authors(Authors,country) Values('Simson','usa')", myConnection );
myCommand.ExecuteNonQuery();
la2.text="New Record Inserted!";
//3 更新数据(Access)
myCommand = new OleDbCommand( "UPDATE Authors SET Authors='Bennett' WHERE Authors = 'Simson'", myConnection );
myCommand.ExecuteNonQuery();
la3.text="Record Updated!";
//4 删除数据(access)
myCommand = new OleDbCommand( "DELETE FROM Authors WHERE Authors = 'David'", myConnection );
myCommand.ExecuteNonQuery();
la4.text="Record Deleted!";
//5 使用DateGrid显示数据
myCommand = new OleDbCommand( "select * FROM Authors", myConnection );
MyDataGrid.DataSource=myCommand.Executereader();
MyDataGrid.DataBind();
