Looping To Drop Temp Tables

Hello,

I have a query that's in development that uses several temp tables. In order to test the query repeatedly while it's being written I have the following code at the beginning to discard the temp tables. This allows the query can recreate the temp tables when called in the code.
if object_id('tempdb..#temp1') is not null drop table #temp1
if object_id('tempdb..#temp2') is not null drop table #temp2
if object_id('tempdb..#temp3') is not null drop table #temp3
if object_id('tempdb..#temp4') is not null drop table #temp4
if object_id('tempdb..#temp5') is not null drop table #temp5

Even though this works, it takes multiple lines of code. One of my queries has to drop 12 temp tables, thus 12 lines of code. I have been experimenting with looping the above as follows:

declare @n as nvarchar(3), @table as nvarchar(10)

set @n = 1
while @n <= 5 begin

set @table = '#temp'+@n

if object_id('tempdb..#temp'+@n) is not null drop table @table

set @n = @n + 1
end

Unfortunately, the above does not work. It gives this error message:
Server: Msg 170, Level 15, State 1, Line 5
Line 5: Incorrect syntax near '@table'.


I have also tried:
declare @n as nvarchar(3), @dropstmt as nvarchar(25)

set @n = 1
while @n <= 5 begin

set @dropstmt = 'drop table #temp'+@n

if object_id('tempdb..#temp'+@n) is not null @dropstmt

set @n = @n + 1
end

This does not work either. It gives this error message:
Server: Msg 170, Level 15, State 1, Line 5
Line 5: Incorrect syntax near '@dropstmt'.

Does anyone know how to get this to work?

Thanks.
