Rather informative, thanks.
Then why C# don't sth like Java where the methods are declared virtual by default?

But it can - you just have to cast it back to a cat. ((cat) z).talk()
The advantage is that you can treat all common properties in the same way. So, you can have a generic series of methods that will work on any animal or class derived from an animal - think of List, which supports Object or anything which derives from an Object - i.e. everything. You don't have to produce a List for Animal and a List for Cat - they can both reside in the same List.

Was this an interview question?
There's really nothing to explain.
Let's say you used ExecuteScalar to return an integer value from a database. The compiler doesn't know that the value is an int, all it knows is that the value's type derives from object. But you, the programmer, know it's an int (and not null) so you tell the compiler:
int x = (int) cmd.ExecuteScalar() ;
This type of cast is not a conversion, it's merely a note to the compiler that assigning the value to a variable of type int is safe.

I am creating a project it contains two textbox.
In first TextBox i paste text from an excel sheet.
On click of button it generates some code set it to text property of Second TextBox.
currently i compile & excute project, generate code and then i paste to my project and then again i compile & execute project again to run this code.
As i can't past the screen shot of that here else i can explain it well anyway if any body want to discuss i am available

Explaining it clearly at the first place didn't look like a good idea to you?

Dear
I have explained my problem as best as i can.
I was meant to say that i was able to explain better if there was a support of pasting image

Unfortunately not well enough for us to understand exactly what it is you are trying to do. I'm wondering whether you're trying to run Excel in your app, or convert information from Excel to C# code, which you want to compile and run. Or perhaps something else...

I am working in an organization in which i update the record to a central tracker. Mostly data provided to me is in Excel.
I pick the data from excel paste it into first TextBox. Data cosist of Two Columns as mentioned below
________________________
Site ID | DN Received |
------------------------
MDWH2813 | 10-May-08 |
MDWH2814 | 10-May-08 |
MDWH2739 | 10-May-08 |
------------------------
i will copy data excluding the header area from the upper section and paste it into 1st textbox that looks like as follow
MDWH2813 10-May-08
MDWH2814 10-May-08
MDWH2739 10-May-08
Then i click on a button and i generates a C# code as under and set as text on 2nd TextBox
updateCentralTracker("MDWH2813","10-May-08");
updateCentralTracker("MDWH2814","10-May-08");
updateCentralTracker("MDWH2739","10-May-08");
currently i copy the generated code from 2nd TextBox. copy it to my solution and rebuild & execute and then i click on the second button that executes the code and data is updated to the Central Tracker.
but i want when i generate the code on first run then i click on the second button and it should run that code at run time
i hope its now understandable
let me know if any query

Instead of trying to recompile on the fly, why don't you just parse the data you are already pasting into the box and issue your command to upload...all in one step?
Maybe I am missing the point but it looks like you are trying to make a simple solution as difficult as possible.

Do you want to automatically compile and run the text you outputted to your second textbox?
That's entirely possible, but before I look up an article about runtime compilation for you I'd like to know whether this was really what you had in mind..
|
|
|
|
|
Yes you are right
i dont want to compile but only execute.
but pasting it at desired place where currently i paste it manually
ignore the last line if you are not able to understand its about sequence/placement of auto. generated code.

Is it not possible to use the information from the text box directly? Something like "updateCentralTracker(string1, string2);"?
Is there some reason you have to create explicit string constants for the parameters?

Thanks for your valuable contribution. both (Searril & molesworth )
Yes that is possible but as this data is going to be update in central tracker and is copy pasted from excel file and there are chances that it can break my algorithm in some conditions when data is not provided to me in expected format. so i want to confirm it once time by watching it.
another point ; i am generating code to avoid loop in case i don't generate code i have to go through each line and apply my algo on it and then to send update to tracker and i cannot also verify it visually.
so it will be best solution to the problem if i can rum my code at runtime in my opinion else there are 101 way to do it.

Don't cross post please.
The web development (you posted there as well) or the asp.net forum is a better forum for this question.

Sorry for cross post. I didn't know which one is more appropriate.

... maybe "whateverYourEditControlIsCalled.SelectedText" ?

In your original post you said :-
jammmie999 wrote: The user selects some text on the HTML editor
From which I guessed meant he was selecting some text area in the editor you're writing.
However, if you're looking for a way to copy text from a browser window, including the HTML formatting tags that go with it, then I'm not too sure about that, as it's not an area I've looked at.
I think (but may be wrong) that using drag and drop you might be able to specify that you want to keep HTML formatting. Possibly paste operations can do something similar.
