.net - Search for a file in a specific directory C# -

-

this question has answer here:

i attempting(without luck) search specific file if exist in particular directory.

for example: search test.txt if resides within directory structure of testfolder(does not have in testfolder have in 1 of subfolders of testfolder). location of testfolder not known.

i have tried this, errors out when hits dir not have access too. 

string[] list = directory.getdirectories("c://", "testfolder", searchoption.alldirectories);

the though find directory , search within directory file.

any appreciated!

the way describe should work (i.e. find directories , search within them).

most got "unauthorizedaccessexception" exception related security system in windows 7.

i suggest add try-catch skip folder can't access
