使用的TransactionScope：System.Transactions.TransactionAbortedException：该交易已中止

我们正在尝试使用下面的代码，.NET 3.5，& SQL Server 2005中使用的TransactionScope：System.Transactions.TransactionAbortedException：该交易已中止

MSDN说使用的TransactionScope时做间接嵌套事务，每当应用程序在事务中打开第二个连接（甚至是同一个数据库）时，事务就会升级。

void RootMethod() 
{ 
    using(TransactionScope scope = new TransactionScope()) 
    { 
     /* Perform transactional work here */ 
     FirstMethod(); 
     SecondMethod(); 
     scope.Complete(); 
    } 
} 

void FirstMethod() 
{ 
    using(TransactionScope scope = new TransactionScope(TransactionScopeOption.Required)) 
    { 
    using (SqlConnection conn1 = new SqlConnection("Data Source=(local);Initial Catalog=Northwind;Integrated Security=SSPI")) 
     { 
    string insertString = @" 
      insert into Categories 
      (CategoryName, Description) 
      values ('Laptop1', 'Model001')"; 
     conn1.Open(); 
     SqlCommand cmd = new SqlCommand(insertString, conn1); 
     cmd.ExecuteNonQuery(); 
     } 
     scope.Complete(); 
    } 
} 

void SecondMethod() 
{ 
    using(TransactionScope scope = new TransactionScope(TransactionScopeOption.Required)) 
    { 
     using (SqlConnection conn2 = new SqlConnection("Data Source=(local);Initial Catalog=Northwind;Integrated Security=SSPI")) 
     { 
    string insertString = @" 
      insert into Categories 
      (CategoryName, Description) 
      values ('Laptop2', 'Model002')"; 

     conn2.Open(); //Looks like transactionabortedException is happening here 
     SqlCommand cmd = new SqlCommand(insertString, conn2); 
     cmd.ExecuteNonQuery(); 
     } 
     scope.Complete(); 
    } 
    }

偶尔，交易失败的是，不促进到DTC，并且我们得到以下的内堆栈跟踪，

System.Transactions.TransactionAbortedException: The transaction has aborted. ---> 
System.Transactions.TransactionPromotionException: Failure while attempting to promote transaction. ---> 
System.InvalidOperationException: The requested operation cannot be completed because the connection has been broken.  
at System.Data.SqlClient.SqlInternalConnectionTds.ExecuteTransaction(TransactionRequest transactionRequest, String name, IsolationLevel iso, SqlInternalTransaction internalTransaction, Boolean isDelegateControlRequest)

at System.Transactions.TransactionScope.SetCurrent(Transaction newCurrent)  
at System.Transactions.TransactionScope.PushScope()  
at System.Transactions.TransactionScope..ctor(TransactionScopeOption scopeOption)

任何人都可以请帮我找出这个原因失败？

你试过关闭连接吗？有时候，当连接已经打开时，我确实会发生这样的错误。可能是我可能是错的。 –

你有没有试过在连接字符串中加入*; MultipleActiveResultSets = True * –

我可以向你提出一个更好的方法来实现你的目标。每个连接应该有一个针对2个数据库调用的事务。

应该像

using (SqlConnection conn1 = new SqlConnection("Data Source=(local);Initial Catalog=Northwind;Integrated Security=SSPI")) 
{ 
    using (conn1.BeginTransaction() 
    { 
     try 
     { 
      FirstMethod(Conn1); 
      SecondMethod(Conn2); 
     } 
     catch() 
     { 
     } 
    } 
}

你不能说这是更好的解决方案。如果你不能改变接受连接的方法怎么办？如果这些方法在不同的对象中呢？如果这些方法已经有太多的参数呢？这也很丑陋。 –

如果您使用的TransactionScope你：

超过开启一个连接到数据库，并
被连接到SQL Server 2005服务器

该交易将升级为DTC。检查此其他等问题：TransactionScope automatically escalating to MSDTC on some machines?

的解决方案可以是：

使用SQL Server 2008或

使用的SqlTransaction代替的TransactionScope就像前回答提示：

using (var conn = new SqlConnection(connectionString)) 
{ 
    using (var tx = conn.BeginTransaction()) 
    { 
     FirstMethod(conn); 
     SecondMethod(conn); 
     tx.Commit(); 
    } 
}
