A few weeks back, everything was working fine, and I've checked this on half a dozen computers with a similar setup and cannot reproduce the problem anywhere else.

The Watcher simply doesn't find all the files in the directory - only if the files are placed in the folder one by one - not if lots of files are copied to the folder at the same time... Is the creation of Threads the solution to the problem or is there another way to handle the problem ? 回答1: The documentation on that class details that problem: The Windows operating system notifies your component of file changes in a buffer

I have a loop in my program that gets a line from a file. Then there is a check to whether the line contains a string if ( line . Contains ( "String" )) { //Do other stuff } There are over 2 million rows in the file so if I can quicken the speed by even 1/10th millisecond then this would save me over 3 minutes on each run. So... Say a line is 1000 chars long, is it quicker to look for a short or long string, or does it not make a difference? line .
