Query WHERE IN clause not working

In a SQL query we are using WHERE IN clause to filter the data. When I am passing 35000 fields in WHERE IN clause, The ExecuteNonQuery throws

Object reference not set to an instance exception

I have used try catch in where the ExecuteNonQuery excuted, but the exception not catched current method, it catched in parent method (button click)

If I reduced the count from 35000 to 25000 the SQL query works fine. Please help.

SELECT * FROM COUNTRY WHERE CountryID in ('1','2',......'35000')

I have tried to use Temp Table in SQL also, Same error happened.

IF OBJECT_ID('tempdb..#temp)IS NOT NULL DROP #TEMP 
CREATE TABLE #TEMP
( CountryID int NULL)
INSERT INTO #TEMP VALUES ('1')
.
.
.
INSERT INTO #TEMP VALUES('10')

SELECT * FROM COUNTRY WHERE CountryID IN(SELECT CountryID from #temp)

The object null reference error is not the problem, How can i overcome the Where In clause issue in sql query. What would the possible resolution to avoid the Where in clause in sql query.

Please help. Thanks.

Use join instead, this should work

SELECT * FROM COUNTRY c INNER JOIN #temp t on c.CountryId=t.CountryId

Why not just use between?

SELECT * FROM COUNTRY WHERE CountryID between 1 and 10
