Check File existence over HTTP using C#.net

[j_vijaydaniel]

Hi All..

I have a windows C#.net Application 1.3 which has Uploading and Downloading work over http to local system as well as local system to http.
My application runs through Web Service.

I encoded Downloading and Uploading options through the Client Windows application itself.

My problm is I am not able to check the File Existence over HTTP. Its throwing only exception if i do so.
Its urgent.
Pls help.. Thanks a lot in Advance..

Regards.,
Vijay Daniel

I could be wrong, but the only way you can check for a file is to try to download it from what you believe is its full Url (http://www.mysite.com/files/myfile.bin) and then you can catch Error 404 (File not found).

There may be a better way, but I dont know of it.

Thanks for ur reply buddy!! Currently i checked my file existence over HTTP thru Catch method only. But at times it always moves on to Catch giving me a message that " This file does not exists in "http://203.303.11/test"
This s a custom message given by me only.
I need a code to check a file in the Web Server ie, http.

Thanks

Could the web service not check for the existence of the file and throw a specific exception if it is missing?

The client would then catch this exception and know the file wasnt there.
