When I used Datatable.Expression = [1874 characters] BUT it stops reading/running..
Is there a Max Length on this? How can I make my very long "expression string" works?
Expression is a string so I doubt there's a real limit. You might have a bug in the text/expression you are using. But really, if your expression is that long, you might want to rethink what you're doing. I, for one, would not want to maintain or deal with
an expression that long; what a nightmare that would be.
But it seems there is a limitation.. I understand that the expression is too long but the design of this process is dynamic and that expression is not possible.. the expression is just like this btw... "1 + 2 + 3 + 4...." (up 1800+ characters)...
Do you propose other "expression" way or something?
If possible, you might do some of the processing in a stored procedure perhaps. Or perhaps use LINQ to facilitate maintenance. It's hard to say wihtout knowing more.

Hi Everyone,
When I used Datatable.Expression = [1874 characters] BUT it stops reading/running..
Is there a Max Length on this? How can I make my very long "expression string" works?
Thanks...

@ Kurai
likely, you'll need to use the debugger* at least to provide your peers here with better information.
with the minimal information that you've provided, it's difficult to help you; for example, you've not shown us the relevant snippets of your code.
what is it ????????
what about 1873, 1872, ... and lower?
