Is it possible to wait for a file to be created to continue in c# asp.net
im currently working on a report builder for the buisness I work for. 

I have a little problem with the big files generation. 
The code just ignores it when crystal reports and CSLA has been working for too long. I changed settings in iis and it didnt changed anything. 

Now i wish to know if there is a way to stop the code until the file i create is present. 

I hope my uestion is clear. (My english is not as good as it should be ).
