string[] connstr= new string[3];
connstr[0] = "server =192.168.0.25;database=db01;uid=sa;pwd=";
connstr[1] = "server =192.168.0.25;database=db02;uid=sa;pwd=";
connstr[2] = "server =192.168.0.20;database=db03;uid=sa;pwd=";


try
{
using (TransactionScope scope = TransactionScopeBuilder.CreateReadCommitted())
{
using (SqlConnection connection1 = new SqlConnection(connstr[0]))
{
try
{
connection1.Open();

// if (insertthegjd(connection1, 1, gjdwillupload, gjdmaindc) < 0) // this is i comment the codes because i doubt if they made the connection stoke,but when i comment them, the connection open is still stoke in connection2.open()
// return 10;

connection1.Close(); // this is i though if the connection1 is close,so i close it!

}
catch (Exception ex)
{
throw ex;
}




}



using (SqlConnection connection2 = new SqlConnection(connstr[1]))
{
try
{

connection2.Open();// the program is stoke in here,i have tried many ways,but they are not work

// if (insertthegjd(connection2, 2, gjdwillupload, gjdmaindc) < 0)
// return 10;


connection2.Close();

}




catch (Exception ex)
{
throw ex;
}


}


using (SqlConnection connection3 = new SqlConnection(connstr[2]))
{
try
{
connection3.Open();

// if (insertthegjd(connection3, 3, gjdwillupload, gjdmaindc) < 0)
// return 10;
connection3.Close();

}
catch (Exception ex)
{
throw ex;
}

}










// The Complete method commits the transaction. If an exception has been thrown,
// Complete is not called and the transaction is rolled back.
scope.Complete();

return 1;
}
}
catch (TransactionAbortedException ex)
{
throw ex;
}
catch (ApplicationException ex)
{
throw ex;
}


//the following is i search in Stackoverflow,to change the isolation level

public static class TransactionScopeBuilder
{
/// <summary>
/// Creates a transactionscope with ReadCommitted Isolation, the same level as sql server
/// </summary>
/// <returns>A transaction scope</returns>
public static TransactionScope CreateReadCommitted()
{
var options = new TransactionOptions
{
IsolationLevel = System.Transactions.IsolationLevel.ReadCommitted,
Timeout = new TimeSpan(0, 3, 0)
};

return new TransactionScope(TransactionScopeOption.Required, options);
}
}


many thanks
