Create dynamic Name for string

[KaHuNa]

I want create a string from a row of my db, but for each rows i need a new
string and a new name for the variable.

exemple:
int i = myRow["ID"];
string varName = "news";

createNameVar = varName + i;

but i can't eval this in C#, also the strings news1, new2,...,newsN don't
exist.
How i can do that?

Why do you need a new name for the variable? Why not just use an array?

Because i use the string to send the variable in a Macromedia Flash
interface.

You don't really need a new name for the variable
If you need to hold all the news strings at the same time you can use an
array or ArrayList

ArrayList newsList = new ArrayList();

foreach(row r in table.rows)
{
int i = r["ID"];
newsList.Add("news" + i);
}

newsList will then hold all the strings. You only need the reference, not
the name.

You need to be a bit clearer on exactly what you're doing here. How
does the Flash interface work, etc. If you could produce a really
"dummy" version of what you're trying to do (which needn't be related
to the real thing) that would help a lot. It could be that reflection
is what you need, but it's hard to say without more information.

You can always send these strings to flash
foreach(string s in newsList)
{
send s to flash
}

ok take this exemple:
you have a text file with a="abc"
you load the line and you have a string, but you can use the variable a.
With eval in jscript you can create a="abc" with a is the variable.
I want the same function in c#, a function which evaluates the string to
make varaibles....

Well, you can't - but if you'd explain more *why* you want this, *how*
you were going to use it, we could help to explain what to use instead.

Are you perhaps trying to ouput these values into a text file that is then
read in by Flash (which will then assign values in the text file to
variables within its own programming environment) ?

In that case just output " strings" that you build up into that text file...

Pseudo code:

for each row x in my data...

varForFlash = "news" + x + "=" + dataIwantVarToEqual

Ouput varForFlash to text file

next row

This will give you a text file with:
news1 = firstRowData
news2 = 2ndRowData

etc...

Flash will then be able to consume...

I hope this helps, if not then please provide clearer details on what you
are doing as suggested by the others..

Cheers

I think this method could be fine, because i can make the eval in flash and
the server works less....
thank you.

Flash will do that more or less for you :
