Question

i am writing a console app in c# to check if file ‘id’ in sql server table matches filename of file on local directory…i know how to use filename to check a location(all this does is check file exists in local directory)…

for example if there was an entry in a sql table of value ‘925677bb-cabb-4ff1-8c90-3e130a77b366’…i would want to perform check on location (c:\…) where any files with that filename would exist, ie ‘925677bb-cabb-4ff1-8c90-3e130a77b366.jpg’

what would be the best way to do this?

Answer 1

You could use the File.Exists function:

string id = ... go and fetch from your db
string filename = Path.ChangeExtension(Path.Combine(@"c:\somefolder", id), ".jpg");
if (File.Exists(filename))
{
    // the file c:\somefolder\925677bb-cabb-4ff1-8c90-3e130a77b366.jpg exists
}
