1. void StartProcess()
2. {
3. // do your stuffs here
4. // call the same method again, when all stuffs done
5. StartProcess();
6. }
Have a look an example of recursive methd, send the data to the API when you have data in your JSON file, otherwise call the same function to read the next value (if available)

can you please elaborate how to do in recursive way .some sample code for this

I ll prefer you to do this method in a recursive way and not by using a while loop, the next request will only being sent when it com0letes the current one, this will become more efficient than usimg while loop

yes it is window service check for new request every time .secondly after request it is written for delete but it skips and go further

This is due to usimg of while loop

while (true)

{

SqlDataReader rdr = null;

...

}

Avoid using this and then execute your code, is there any specific using while loop?

This will also leads to degradation in application performance.
