System.Web.UI, System.Web.UI.WebControls, System.Web.UI.HtmlControls,

System.Web.Security, System.Web.UI.WebControls.WebParts, System.Configuration;

-------代码部份如下-----------------------------

procedure TDefault.Button1_Click(sender: System.Object; e: System.EventArgs);

var s:string;

CNN:SqlConnection;

COMM:SqlCommand;

Query:SqlDataReader;

begin

s:='Data Source=LocalHost"MSSQL;Initial Catalog=pubs;User ID=sa;Password=admin';//连SQL-Server的字串

CNN:=SqlConnection.Create(s);

CNN.Open();

COMM:=CNN.CreateCommand();

COMM.CommandText:='select * from employee';

Query:=COMM.ExecuteReader;

while Query.Read do begin

Response.Write(Query['fname'].ToString()+'   '+Query['lname'].ToString()+'<br>');

end;
