Hi, I am finding difficult on copying a file from folder to folder, actually in a Folder A there are audio files of mp3, wav and dss, i want to copy the file by giving the filename but without extension. Below is the code, if i try i am getting error as illegal path.

Kindly help

C#

string filenumber = textBox1.Text ;

string soureFile = @"C:\Folder A\";
string targetFile = @"D:\Audios\";

string sourceFile = System.IO.Path.Combine(soureFile, filenumber);
string destFile = System.IO.Path.Combine(targetFile, filenumber);

string chifex = sourceFile + filenumber;
if (File.Exists(chifex))

what happens if "C:\Folder A\" contains song1.mp3 and song1.wav? which file will be copied? why is the extension ignored?

It is not possible to do what you are trying to do. To access a file, you are required to give the full file name including the extension. Sorry!

It is not possible directly but you can do by customizing your code.
following code gives you list of files regardless of extension

C#

string[] filePaths = Directory.GetFiles(@"C:\MyDir\", "1.*",SearchOption.AllDirectories);

it will return files having name 1 with all extensions.

C#

string[] files = Directory.GetFiles(soureFile, filenumber + ".*");
foreach (string file in files)
    System.IO.File.Copy(file, System.IO.Path.Combine(targetFile,System.IO.Path.GetFileName(file)));
