• how move file has no file extension? c# 3 answers

the file test has no extension , need either move or rename file extension

if(file.exists(@"c:\\users" + environment.username + "\\desktop\\test")) {                                                                 /\                                                file has no file extension } 

i created file named test no extension in folder m:\incoming.

running following code works in both cases:

if (file.exists(@"m:\incoming\test"))     console.writeline("exists");  if (file.exists(@"m:\\incoming\\test"))     console.writeline("exists"); 

when using @ not need specify 2 slashes, although makes no difference anyway in example.

output:

exists

exists

your problem in way in concatenating strings.
