Use

checked

Like in example bellow:

try
{
    // The following line raises an exception because it is checked.
    z = checked(maxIntValue + 10);
}
catch (System.OverflowException e)
{
    // The following line displays information about the error.
    Console.WriteLine("CHECKED and CAUGHT:  " + e.ToString());
}

Where does the "e" comes from. What does "e" mean?

Look at type

catch (System.OverflowException e)
        { ...

e is my variable name it is short for exception. It is not obligatory to use any name if you wanna catch OverflowException without more information.

How to save treeview in database ???

See here: checked (C# Reference)[^]
Or you can enable it for the whole app:
Go to project Properties and find the Build tab.
Click "Advanced" button.
In the resulting dialog, check the “Check for arithmetic overflow/underflow” box, and press OK.

This is not a good question - we cannot work out from that little what you are trying to do.
Remember that we can't see your screen, access your HDD, or read your mind.
Edit your question and provide better information.

It's probably a question to him!
Trouble is he is so close to it (and likely English is not his first language) that he didn't consider that we need more than that. It's all he needs, because he knows what he is doing, and assumes there is only one way to do it, and we know what that is! Laugh | :laugh:

Ask the user.

You'll never get very far if all you do is follow instructions.

Unless you want to search the entire file system of the device, and in the event of multiple files with the same names GUESS at which one is the correct path, you're going to have to ask the user.
