Code Tester Webpart C#

Hi, Sharepoint is like a candy, sweet, but this webpart make this more sweet, i was looking in codeplex and saw this webpart and i think "iisreset, forget me" 2 or 3 minutes waiting see some sharepoint page, Code Tester webpart, but this can be a break of security because you can call all .dll inside the server and delete your c:\ and other things like sharing and sending emails with server details, please just use in your develomp zone, and with responsable persons...

You problably have this problem i ask to heaven "WHY?????", well the answer is bad code, yes i do have the read 12 times the sdk to follow the microsoft good source code.
I have this problem, and .AllowUnsafeUpdates = true; dont answer because the using method was bad, then i find this Post this give some ligths on my BAD code :P .


But first We have to read the best pratices by microsoft, after reading this well, hope dont have this problem anymore....

//simple steep
String str;

using(SPSite oSPsite = new SPSite("http://server"))
{
using(SPWeb oSPWeb = oSPSite.OpenWeb())
{
str = oSPWeb.Title;
str = oSPWeb.Url;
}
}

//This steep is the most complete but like microsoft say Response.Redirect WILL NOT execute the finally block
String str;
SPSite oSPSite = null;
SPWeb oSPWeb = null;

try
{
oSPSite = new SPSite("http://server");
oSPWeb = oSPSite.OpenWeb(..);

str = oSPWeb.Title;
if(bDoRedirection)
{
if (oSPWeb != null)
oSPWeb.Dispose();

if (oSPSite != null)
oSPSite.Dispose();

Response.Redirect("newpage.aspx");
}
}
catch(Exception e)
{
}
finally
{
if (oSPWeb != null)
oSPWeb.Dispose();

if (oSPSite != null)
oSPSite.Dispose();
}

So after you learn this first litle steep i start to understan whats wrong with my code, and understand what Kjetil Gullen do.


Thanks Kjetil Gullen.
