Transaction Scope and MSDTC

Question

Dear sirs,
i am using ADO with C#, in transaction scope (inside using{ }) i call many functions that need to connect to database, about 5 of them use ExecuteReader , ExecuteNonQuery,...
but last one uses SQL Data adapter

C#

conn.Open();
dbAdapter.Fill(datatable);
conn.Close()

(i know that i can fill the dbAdapter with open and close connection)
it open a connection correctly but on (dbAdapter.Fill(datatable);) it throws an exception "MSDTC not available " and i don't want to run the MSDTC service that question is : why throw an error if the connection opened and why not if the connection is not opened again () before filling and if i remove the open before filling may this make errors on other (like ExecuteReader , ExecuteNonQuery,...) or not
and is there a better way to use instead of transaction scope

Regards.

Try this Commitable trasaction

SqlConnection concTx = new SqlConnection(ConfigurationManager.ConnectionStrings["Constr"].ToString());
cTx = new CommittableTransaction();
try
{
concTx.EnlistTransaction(cTx);
//excecute your query function morethan one
cTx.Commit();
cTx.Dispose();
concTx.Close();

}
catch (TransactionException te)
{
cTx.Rollback();
cTx.Dispose();
concTx.Close();

}
catch (SqlException sqE)
{
cTx.Rollback();
cTx.Dispose();
concTx.Close();

}

catch (Exception ex)
{
cTx.Rollback();
cTx.Dispose();
concTx.Close();

}

Note:Use ONly this Single "concTx" connection for all this operation Dont forgot the header file
using System.Transactions;
