Hi,
exception is a way to provide information about an unusual behavior in a method. Sometimes this behavior is caused by an error. What you want is the error code. So the "default" Exception class you are catching does not provide an error code
http://msdn.microsoft.com/en-us/library/system.exception.aspx[^]
But if the specific class of the exception thrown by the called method contains a code, than you can receive this code by accessing the property from the exception (you have to cast before or catch a more specific type).
If you need further help I recommend to post the code also, causing the exception.
Regards
Sebastian

1) for example : System.FormatException
try
{
int i = int.Parse("Hi Thanks for your Help!");
}
catch (Exception ex)
{
Type tp= ex.GetType();
}
catch (FormatException Fex)
{
Type tp= ex.GetType();
}
2) where we can get all Exception types?
|

1) you have to catch the FormatException first. And as second one the common Exception. When not, the FormatException will never be catched, because a FormatException is an Exception.
2) Nowhere, because Exception are classes which can be derived from. So there are thousands of Exception types out there (waiting to be catched  ) (For all framework exceptions you can browse through msdn...)
3) Maybe you can explain what you want to achieve? To get an idea for exception handlung start reading this msdn article:
http://msdn.microsoft.com/en-us/library/ms173160.aspx[^]

Before all Thanks for your attention and Help !
I want to translate Exception to my Language (Persian,Farsi) then show the translate exception.(Note: I dont want to write down the error in catch like bellow:
try
{
}
catch
{
messagebox.show("Not like this");
}
OR
try
{
}
catch(Exception ex)
{
messagebox.show("Not like this");
}
OR
try
{
}
catch(FormatException ex)
{
messagebox.show("Not like this");
}

Isn't this exactly the same question that you posted three hours ago under the title ERROR?
It is generally considered bad form to post the same question multiple times.

You have been give the answer to this already; try reading the MSDN documentation on C# exceptions.

U can open a dialog by following way(Win7 OS):
Control Panel\All Control Panel Items--Network and Sharing Center
bellow View your active networks
CLICK Connections:local area connection ,you can see a window about local area connection status.
I want to get information on this window,such as
General-Connection-
IPV4 Connectivity : Internet
IPV6 Connectivity : No network access
Thanks very much!
-------------------------------------------------------------
i find that IPV4 Connectivity value is a best way to detect the availability of Internet.Using Ping Ip or get request from server is NOT a reliable way.

I've used wmi ever ,but the API called Win32_NetworkConnection don't fit my requirement.
or
[DllImport("wininet.dll", ExactSpelling=true, CharSet=CharSet.Ansi, SetLastError=true)]
private static extern bool InternetGetConnectedState(ref int lpSFlags, int dwReserved);
I only want to get the status the same as I mentioned from my question.

But Jhon Simpson the Outlow programmer answeared your question.
Use
cmd.Parameters.AddWithValue("@name", name);
cmd.Parameters.Add("@name", name);
As a side note, in order to work your class should extend the abstract class

hi all,
im new to the c# world..
there is some error showing on my test program..

using VS2008 pro to code..
wat is tat suppose to mean??
anyone can help me??
any help are deeply appreciated..
thank u..

Well you have a value/variable that is trying to be converted into another datatype which is not allowed such as;
DateTime testValue = Convert.ToDateTime(23);
This will also cause an "InvalidCastException" if it is not handled in a try/catch block.

Hi,
you tried to cast an object which wasn't able to cast (maybe it is null). If you post the code, it could be possible that we spot the line...

object ICOSDriver.Document
{
get
{
//return null;
throw new NotImplementedException();// ==>> shows error here while debug.
}
}
thank u..
|
|
|
|
|
I guess returning a null value will fail by the code consuming the ICOSDriver.Document property. Where do you use the property?
