Question

Whats wrong with following code? 🙁

int? parentFolderId = null;
if( this.Request.QueryString ["folderId"] != null )
    parentFolderId = Convert.ToInt32( this.Request.QueryString ["folderId"] );
f = ( from x in this.EntityDataContext.folders
        where x.parent_id == parentFolderId
        select x ).ToList();

It returns nothing! Though there ARE records in database with parent_id as NULL.

However, when I explicitly state NULL; it works!

f = ( from x in this.EntityDataContext.folders
        where x.parent_id == null
        select x ).ToList();

What could be the issue?

PS: I hate working with mysql using Entity Framework …. every damn simple thing has million issues!
