Hi! Simple C# question, I'm just wondering the the connection will close in the code below:
try {
connection.Open();
command.ExecuteNonQuery();
throw new Exception();
} catch(Exception) {
throw;
}
finally {
connection.Close();
}

yes becouse finally block gets excecuted in any situation whether there is exception or code excecutes successfully.

So, in the statement sequence, will the connection.Close() be executed before or after the exception is rethrown in the catch(...) block?
If after, what if this whole thing is contained in another try... catch statement, will the catch statement in the parent next be executed first?

What happened when you tried? All you are asking can be easily checked by writing a simple program.

haha okay okay, i'll try then.

it will excecuted after the exception is rethrown and the outer catch block will be excecuted next.

You're right! I just made a small experiment as Navaneeth suggested and it looks like the case.
Thanks much!

Have you checked the InnerException value?

The namespace name would be different. Also this is not the correct forum. Try ASP.NET forum.

XMLDocument class provides a DOM model access to the XML file and it allows you to read and write. It uses XMLReader for reading and XMLWriter for writing.

Do you know anything about web services ? Have you written one ?
A web service is imported into your project and it's methods exist for you on a class that you call.

Well, a better choice is to read a book than posting in forums. When you import a webservice to your project, VS will create proxy classes to access the WS. You only need to call these classes by specifying values as parameters.

To expand on Navaneeth's response. I mean that you obviously have no idea, so you should either read a book, try to write some code and follow an online tutorial, or just plain give up before you ask questions that only show that you're not far enough along to stand much of a chance of understanding the answer.

1. Don't post the same question twice.
Reply to your original post right below.
2. Use a descriptive subject line.
3. Read the post by Chris Maunder, "How to get an answer to your question"[^]

Typically, all processes and services should have a mechanism to be stopped or started as a user selects. Anything else is almost always designed for malicious intent.
