如何在事务中止时获取错误详细信息

Question

我正在使用System.Transanction和TransanctionCompleted事件来检测异常事务。

我该如何找出失败的原因？是一种检测错误细节的方法吗？

Answer 1

你可以在你的交易方法赶上System.Transactions.TransactionException

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; 
} 

交易完成事件处理

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); 
}
