c# exceptions

[npa]

if, when using c# with asp.net, we have an exception that
we do not catch, i.e:

string s = null;
Response.Write(s.ToString());

we get the exact line numbers, etc, output when the
page displays the exception to us. we also get the
previous calls that have got us to this point (methods,
etc).

however, if we do something like:

// Page_Load(){
exceptionCheck();
// }

public void exceptionCheck(){
 try {
  throw new Exception("test");
 } catch(Exception e){
   Response.Write(e.ToString());
 }
}

we do not get the line-numbers from where this
method was called ... (exceptionCheck). why ? is it
just my setup ? i really need to have this ability
but i just can't figure it out .... i hope i am clear.

i wish i could help .. i haven't worked much with asp.net .. but lots with c#.

it's nice to see someone else around here working with c# too =)

please post if you find an answer elsewhere.

Use the StackTrace property:

public void exceptionCheck(){
 try {
  throw new Exception("test");
 } catch(Exception e){
   Response.Write(e.StackTrace);
 }
}

sdeming, the .toString contains that data already ...

the answer is actually to do:

catch(Exception e){
  System.Diagnostics.StackTrace st = new ... StackTrace();
  Response.Write(st.ToString());
}

you will, however, need to have "debugging" enabled
in your project. (or something like that).
