Question

Basically, I have this code:

DirectoryInfo dir = new DirectoryInfo(@'\\MYNETWORK11\ABCDEFG\ABCDEFGHIJKL\00806\'); FileInfo[] files = dir.GetFiles('200810*'); 

I expect it to match any files starting with 200810. However, it’s matching files named

20070618_00806.bak and 20070817_00806.bak (the stars aren’t in the filename, that was the only way I could include the underscore)

I tried it with dir from a command prompt, and it matches those files also. Why?

Edit:

Maybe using C: as the example was not a good thing. The directory I’m actually querying is a network share \\MYNETWORK11\ABCDEFG\ABCDEFGHIJKL\00806\

If checking against the short name has anything to do with it, won’t 20070817_00806.bak be 200708~1.bak? That doesn’t match either

Answer 1

msdn states that

‘Because this method checks against file names with both the 8.3 file name format and the long file name format, a search pattern similar to ‘*1*.txt‘ may return unexpected file names. For example, using a search pattern of ‘*1*.txt‘ will return ‘longfilename.txt‘ because the equivalent 8.3 file name format would be ‘longf~1.txt‘.’

Could this be the cause?
