It is possible to read files located on any hosts?

Hello,</o></o>It is possible to read with Visual Studio 2003 / 2005 files located on anywhere on any hosts ?</o></o>I wrote the following line code with both Visual 2003 and 2005 :</o></o>
File.Open ("http://www.wwv-it.de/Statistic1.txt", FileMode.Open, FileAccess.Read,FileShare.Read); </o>
</o>
I got the following error:</o>
Exception Details: System.ArgumentException: URI formats are not supported.</o>
</o>
Thank you in advance for your answers!</o>

You'll have to pull the file over HTTP. try something like this...

Hi Joel,</o>
</o>
Thanks a lot!</o>
I have converted your Visual Basic class to Visual C#.</o>
It works fine.</o>
I use that class / methods to read text files derived from Excel maps (.csv) or Word tables. </o>
Then I convert the data to DataSets for uploading in database tables.</o>
I have enclosed the Visual C# class.</o>
