I want to move this code out of the while loop and place it in a seperate method , what is the best way improve the performance of the application

Implementing the code as a static method, or a non static method

Note: The code contains objects like Datasets, Datareaders, and data adapters whic

Answer 1

There is almost no difference between calling a static method and calling an instance method. There is a slight difference since one is doing CLR call and the other doing virtual call and CLR has to navigate the types to find the implementation but that is really negligible .

Your main concern here must be readability when you have a 1000-line code rather than performance. Whatever you do, calling your database will be the slowest part of your code so instead focus on refactoring .

Answer 2

静态或非静态对您的情况没有影响。

Answer 3

I would move the code into the DoWork method of a BackgroundWorker . This way, your code can run in a background thread, give periodic progress updates to the main UI thread, and let the UI thread know when the operations are completed by invoking the WorkerCompleted event.
