Verification of file existence

Anusha Byna

Scenario : File abc.txt verification

If file exists then call method1()

else

verify the file location(C:\lfs\abc.txt) for every 10sec until the file is found and when the file is available, call the method1().

Since I'm beginner, done scripting for the file existence case but stuck at the verification of every 10sec. Any suggestions for this scenaio will be great

Thanks

hi,

you can use timer to check every 10 seconds, code sample as shown below

First create a function to varify the location and if file availble call that method1() which you have already wrtten .

declare globally below code(outside function)
System.Timers.Timer AutoTimer = new Timer();
then write these below code in main function in your case inside else condition
AutoTimer.Interval = 1000*10;//set interval of 10 seconds

AutoTimer.Elapsed += new ElapsedEventHandler(YourFunctionNameToCallEvery10SecWhichYouhaveWrittenAlready);

AutoTimer.Start();
inside method1() write

AutoTimer.Stop();
to stop checking file again.

Thank you.

Hi. For file existence you can check, if(File.Exists(filename)). For 10 sec time you can use Timer. For more you can follow up with this article, https://www.c-sharpcorner.com/article/timer-in-C-Sharp/
