• Re: Should I use an abstract class or an interface?

  You should probably have both . The interface then an abstract class for the common implementation of that interface.

• Re: Parallel computing in .net 3.5 Sp1 to read large chunk of textfile

  1) why are you using a stringbuilder? My gut feeling is that no, parallelism wont really help your code. This looks like code that will be very IO bound. A very simple test would be to add another loop which simply reads the lines off the disk and throws them away. The difference in performance you see between the two loops is approximatly the difference in performance youd see from parallelizing.

• Re: Parallel computing in .net 3.5 Sp1 to read large chunk of textfile

  From the sounds of it, you might have some luck with using the Jet text drivers and treating these files like a database source.

• Re: Unable to cast object of type 'SoftwareArchitects.Web.Configuration.CachingSection' to type 'SoftwareArchitects.Web.Configuration.CachingSection'

  This generally indicates a versioning issue where you have two different versions of the assembly.

  basically you'd take the info from Much ADO about text files to construct your connection string and feed that connection string into an OleDbConnection .

• Re: IENumerable selecting indexes

  If you're trying to implement paging w/ linq to sql or entity framework use: var selection = products.Where(...).Skip(pageIndex * pageSize).Take(pageSize); The other two solutions will perform the full query and filter the indexes on the app-server where as linq to sql will emit sql to only bring back the results you want which will perform much better.

• Re: Performance metrics/baseline tools

  I'm not sure I understand the question. It looks to me like the type of data you're looking to gather would require specifically instrumenting an application. Are your users complaining about or do they percive the site as 'slow'?

• Re: ASP.net C# Cron Service

  I wrote a custom scheduler for a place once. It sucked. This type of service always ends up needing a data-store of some sort. If the db requirement is an issue consider that Quartz can be configured to use SQLite as its data-store. Also consider: Dont reinvent the wheel unless you plan on learning more about wheels . If learning more about how this type of application works is your goal. By all means write your own.
