VB.NET WITH command convert to C#

Having Finally passed the MSAD exams in C#, i thought that i should start looking to use these new skills in the code behind to programme excel 2003, so I start work on the examples given on the Visual Studio Tools for Office but they are for VB.Net and i come across a problem when trying to convert a section of code that uses the WITH, END WITH command e.g


VB.NET

With this.Application.CommandBars("Task Pane")
.Width =300
.Position = Microsoft.Office.Core.MsoBarPosition.msoBarLeft
END WITH

so i try to convert it to C# :

this.Application.CommandBars("Task Pane").Width = 300;
this.Application.CommandBars("Task Pane").Position = Microsoft.Office.Core.MsoBarPosition.msoBarLeft;


But it will not compile

ERROR:
'Microsoft.Office.Interop.Excel._Application.CommandBars' is a 'property' but is used like a 'method'

As anyone got any ideas.

I have also tried to get hold of the CommandBar object using this:

Office.CommandBar z = this.Application.CommandBars("Task Pane");

z.Position = Microsoft.Office.Core.MsoBarPosition.msoBarLeft;

but I am still getting the same error.
