<b>ASP.NET mssql server衔接数据库</b>[网站编程]

//

public partial class _default : system.web.ui.page
{
protected void page_load(object sender, eventargs e)
{

}
protected void btn_sendmessage_click(object sender, eventargs e)
{

sqlconnection conn = new sqlconnection(@"sever = .sqlexpress;database=guestbook; trusted_connection=true");
string sql = "insert into tbguestbook (username,posttime,message,isreplied,reply) values ('test','2006-11-1 12:00','www.hackline.net',0,'ac')";
sqlcommand cmd = new sqlcommand (sql, conn);
conn.open();
cmd.executenonquery();
conn.close();

}

//衔接数据库后再查询数据

private void page_load(object sender, system.eventargs e)
{
if(!ispostback)
{
string myconnectstring = "server=localhost;uid=sa;database=manager ";
sqlconnection myconnection =new sqlconnection(myconnectstring);
string comstring = "select * from newstudent ";
sqlcommand mycommand = new sqlcommand(comstring,myconnection);
mycommand.connection=myconnection;
myconnection.open();
dataset ds=new dataset();
sqldataadapter mydataadepter =new sqldataadapter(comstring,myconnection);
mydataadepter.fill(ds, "newstudent ");

datagrid1.datasource=ds.tables[ "newstudent "].defaultview;
datagrid1.databind();
datalist.datasource=ds.tables[ "newstudent "].defaultview;
datalist.databind();
}
}

//办法三

在vs中的web.config文件里面可以设置的,
<connectionstrings>
<add name="sqlconnectionstring" connectionstring="data source=pc-200909160824; initial catalog=shopping; integrated security=true"></add>
</connectionstrings>
data source是衔接的数据源,initial catalog是你要衔接的数据库名,integrated security阐明你衔接数据库的方法为windows身份考证
