If your query is like that, in my opinion you don't need the temp table. Simply try:

SQL

select A.* 
from(select A.field
           ,B.field
           ,C.field
     from tableA A
          inner join tableB B on A.field=B.field
          inner join TableC C on B.field=C.field
     where A.field= 11) as A

i want to use temp table Query in DataAdapter in asp.net

Why? What is the benefit?

Of course you can execute several commands in the same SqlCommand but breaking the logic into multiple statement very often slows down the execution and introduces unnecessary complexity.

Having that said, have a look at Executing multiple SQL statements as one against SQL Server[^]
Especially part "Using SqlDataAdapter for multiple SELECT statements"

A more simplified version that you can use is

SQL

select
A.field
,B.field
,C.field
 from tableA A
inner join tableB B
    on A.field=B.field
inner join TableC C
    on B.field=C.field
where A.field= 11
