SQL Create View query Executes successfully in Management studio but fails in C# code [duplicate]

Here is my code

                   cmd.Connection = con;
                   if (con.State == ConnectionState.Closed)
                   {
                       con.Open();
                   }
                   cmd.CommandText = "Drop View [Picklist]";
                   cmd.ExecuteNonQuery();

                   cmd.CommandText = "CREATE VIEW [Picklist] AS select A.desp_no,A.desp_date,A.custid,A.comp_name,A.ref_no,B.item_code as itemid,B.Pqty,C.serial_no,C.batchno,C.expiry,D.Item_name,D.Item_code,D.Mrp,E.cust_name,E.Address1,E.Address2,E.Address3,E.Phone,E.Email from dbo.Tbl_DespDet A inner join dbo.Tbl_Desp_Sub B on A.desp_no=B.desp_no inner join dbo.tbl_desp_barcode C on c.desp_no=A.desp_no inner join tbl_itemMast D on D.item_id=B.item_code inner join dbo.tbl_CustMast E on A.custid=E.cust_id  where A.desp_no=@despno";
                   cmd.Parameters.AddWithValue("@despno", beobj._Desno);
                   try 
                   {
                       cmd.ExecuteNonQuery();
                       return true;
                   }
                   catch(Exception ex)
                   {
                       return false;
                   }

the same create view statement(with just copy paste) works in Sql Server Management Studio.Some one Help me as i am stuck in this Fix.

update:

the name of view is given as [Picklist] for testing only.even i have tried with removind square brackets and found no difference.
