Linq orderby is ignored

Hello I'm not clear why my linq statement orderby is not working as expected.

  var q = from DirectoryInfo subDirectory
          in item.GetDirectories()
          orderby (item.Name == "TableDefinition" ? 1 : 2), item.Name
          select subDirectory;
  foreach (DirectoryInfo subDirectory in q)
  {
    Execute(subDirectory);
  }

I want the items sorted first by seeing if the name is "TableDefinition" or not, then secondly just by name.

It appears that it's just sorting by name only, in alpha order ascending.

You have to use subDirectory in place of item

var q = from DirectoryInfo subDirectory
        in item.GetDirectories()
        orderby (subDirectory.Name == "TableDefinition" ? 1 : 2), subDirectory.Name
        select subDirectory;
foreach (DirectoryInfo subDirectory in q)
{
    Execute(subDirectory);
}
