Not Able to delete Drawing View

Forums:

Hello Guys,

I am trying to delete DrawingView searching by it's name.
It gets deleted for the first time. But if i will add any base view into drawing then it is not getting deleted.
As an example First i will add the view by Name "A0" then I will add Baseview and after that I will run below code so it will delete the A0 view.
After that I will add the view which name is "A1" and will run the code so at that time it will not delete the A1 view.

Can anyone please help me to solve this issue ?
Below is the code:
