Question

I am using System.Transanction and the TransanctionCompleted event to detect aborted transactions.

How do I find out why it failed? Is a way to detect the error details?

Answer 1

You can catch System.Transactions.TransactionException on your transaction method

try
{
    //Create the transaction scope
    using (TransactionScope scope = new TransactionScope())
    {
        //Register for the transaction completed event for the current transaction
        Transaction.Current.TransactionCompleted += new TransactionCompletedEventHandler(Current_TransactionCompleted);
        // proces the transaction
    }

}
catch (System.Transactions.TransactionAbortedException ex)
{
    Console.WriteLine(ex);
}
catch (System.Transactions.TransactionException ex)
{
    Console.WriteLine(ex);
}
catch
{
    Console.WriteLine("Cannot complete transaction");
    throw;
}

Transaction completed event handler

static void Current_TransactionCompleted(object sender, TransactionEventArgs e)
{
    Console.WriteLine("A transaction has completed:");
    Console.WriteLine("ID:             {0}", e.Transaction.TransactionInformation.LocalIdentifier);
    Console.WriteLine("Distributed ID: {0}", e.Transaction.TransactionInformation.DistributedIdentifier);
    Console.WriteLine("Status:         {0}", e.Transaction.TransactionInformation.Status);
    Console.WriteLine("IsolationLevel: {0}", e.Transaction.IsolationLevel);
}
