You can call base.method1() from the derived class. I don't know of any other way. Although I'm not Anders[^], there could be a way, I just can't think of one. Perhaps someone with more experience can confirm or deny this.
El'Cachubrey wrote: 2. Only way to invoke Base Class method it's mark overriden method with "new" keyword in derived class.
Well, like I said, it might not be the only way. It's a way though. Just be aware that the 'new' keyword causes different behaviour to the override keyword. What you are doing is conceptually something slightly different. Make sure you understand all the behaviour differences and consequences and that they are what you want before you do it. (And don't forget, other people who use your code won't be expecting this, so note it heavily in the comments, or consider naming the methods differently)

Wrong, wrong, wrong. I showed you how to do it.

Wrong again. If you make a "new" method, it completely hides the base version from other objects that use your derived class.

By marking the method in the base class virtual and the method in the derived class override, you are stating that you do not want to be able to call the base class' version directly from an instance of the derived class, and therefore it can't be done.
If, you do want to be able to call the base class' version from an instance of the derived class, then do not use virtual and override.

Well, not *technically*...

What do you mean by embedded database? Something like SQLite[^] ?
|
|
|
|

Yes Sql Lite and also someothers like firebird and perst
but honestly am not quite sure which one to use
do you have any idea which would be good and simple to work
Thanks,
Mamtha

Go with Sqlite. It's good and stable. You will get managed APIs also for accessing it.
|
|
|
|
|
Thanks,
and does SQL Lite support storing of binary data and image formats in it
just wondering,
Thanks.

SQL Compact Edition (SQL CE) is pretty good and you have the advantage of designing your database in visual studio. 
oooo, the Jedi's will feel this one....

Try MS SQL Compact

Thanks Lev and Mirko
but as far as i know SQL Server CE isnt an open source one.
you guys worked on firebird or perst anytime
Thanks

SQL Server CE is free to download as well as to redistribute. Is it a requirement to use open source-material? If so, what are you planning on doing with the source?
Most of the time, it's about money, and it that case, "free" is just as good as "open source".

Thanks Eddy,
yes it is more or less means to the money, but am just wondering that i hope i need not run the CE on the client machines using my application.
mine is not a web but a windows application that i am looking to integrate the database to
Thanks,
Mamtha

Go for SQLite: it's opensource, there is a managed provider, compatible with linq and entity framework and fast.

Thanks Giorgi,
I hope sql lite support storing of binary data in it.
Thanks,
Mamtha

SQL Server Express is free too, I use it for a few things.
Given that the out-the-door price is the same (free), the cost difference would be in:
1) maintenance -- Microsoft maintains it, perhaps more rigorously than a bunch of guys in their free time
2) support -- Millions of SQL Server users, many of them here on Code Project; go to the database forum, nearly all the questions are about SQL server, and most of the answers assume SQL Server
3) eventual migration to SQL Server when you realize you need something better -- you're already there

Hi,
I am processing a large xml file which is about 90MB as follows:
The problem is that every time I process this file, my machine really slows down even after I have completed my work and close the application.
I wonder if I should close the doc after usage?
Any suggestions please?
//xml file path refers to the location of the .xml file...
xmlDocument doc = new XmlDocument();
doc.load(xmlFilePath)
//processing on the file happens here...
