Answer 2

Попробуйте

  SqlConnection con = new SqlConnection(); 
      con.Open(); 
      SqlCommand cmd = new SqlCommand("insert into Penawaran (ID_Paket,Jenis_Paket,Harga_Paket) Values (@ID_Paket,@Jenis_Paket,@Harga_Paket", con)); 
      cmd.Parameters.Add("@ID_Paket", SqlDbType.Int); 
      cmd.Parameters.Add("@Jenis_Paket", SqlDbType.VarChar); 
      cmd.Parameters.Add("@Harga_Paket", SqlDbType.VarChar); // this is int sir how to insert it, still error i write like this 

      cmd.Parameters["@ID_Paket"] = int.Parse(txtIDPaket.Text); 
      cmd.Parameters["@Jenis_Paket"] = txtjenisPaket.Text; 
      cmd.Parameters["@Harga_Paket"] = txtHargaPaket.Value; // this is int sir how to insert it, still error i write like this 
      cmd.ExecuteNonQuery(); 
      con.Close();
