Question

We have a network folder that is the landing place for csv files processed by different servers. We alter the extension of the csv files to match the server that processed the file; for instance a file with the name FooBar that was process by Server1 would land in the network share with the name FooBar.Server_1.

The information I have available to to me is file name: FooBar and the path to the share. I am not guaranteed the extension as there are multiple servers sending csv files to the network share. I am guaranteed that there will only be one FooBar file in the share.

Is there a method in .net 2.0 that can be used to get the extension of the csv armed only with the path and filename? Or do I need to craft my own?

Answer 1

Directory.GetFiles(NETWORK_FOLDER_PATH, "FooBar.*")[0] will give you the full path.

Path.GetExtension will give you the extension.

If you want to put it all together:

string extension = Path.GetExtension(
    Directory.GetFiles(NETWORK_FOLDER_PATH, "FooBar.*")[0]);
