HI!!
i have a problem with ConvertFeatureClass(..) , i have Error "Open featureclass failed"
i Need a help please about this methode! why i have this error ?

private void Conversion2(string fileName, string currentView, string alias)
        {
            string nom_repertoire = System.IO.Path.GetDirectoryName(fileName);

You're more likely to get help if you post in the appropriate forum, which is probably
over in ArcObjects - All Development Languages. When you post there, be sure to
specify which version and service pack of ArcGIS you are using. It will also make
your post more readable if you use the CODE tags and try to preserve indentation.
