Just drop the table and recreate it.

Solution 1

Temp tables are prefixed with #, or ## for global temp tables, and are accessible by objectid.

SQL

CREATE PROCEDURE MakeMyTempTable
AS
BEGIN
IF (SELECT 1 FROM #tempTable /*you can call your table however you want but for a temporary table #*/) IS NULL 
CREATE TABLE #tempTable 
( id int
  --here you define your fields
)
END

Now, for create temp table call the procedure from c# or sql.

below is the store procedure
which check if table already exists in TempDB.
(Temporary tables are getting created in TempDB in SQLServer.)
Drop that table
and will create a table
USE [sample1]
GO

SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
create proc [dbo].[temp]
as

Begin
IF EXISTS
(
SELECT * FROM tempdb.dbo.sysobjects WHERE ID = OBJECT_ID(N'tempdb..#Mytemp')

)

DROP TABLE #Mytemp
ELSE

CREATE TABLE #Mytemp(Col1 nvarchar(100), Col2 int)
End
