TransactionScope：“交易已中止”在某些电脑上 [英] TransactionScope: "The transaction has aborted" on some computers
问题描述
我在C＃/ WPF项目中遇到使用TransactionScope的一些问题。我使用如下所述的TransactionScope：
I'm experiencing some issues using TransactionScope in my C#/WPF project. I use TransactionScope as outlined here:
问题在于这适用于我们大多数用户的计算机，但是我收到了一些来自"交易已中止"的人的报告。错误。
The problem is that this works on most of our users' computers, but I've had several reports from people that get the "The transaction has aborted" error.
代码如下所示：
//执行所有安装操作作为交易
使用（TransactionScope tx = new TransactionScope（））
{
DoSomeTransactionalStuff（）;
//提交交易
tx.Complete（）;
}
// Execute all install operations as a transaction
using (TransactionScope tx = new TransactionScope())
{
DoSomeTransactionalStuff();
// Commit the transaction
tx.Complete();
}
...
void DoSomeTransactionalStuff（）
{
if（Transaction.Current！= null）
{
    Ktm.IKernelTransaction tx =（Ktm.IKernelTransaction）TransactionInterop.GetDtcTransaction（Transaction.Current）;
    IntPtr txh = IntPtr.Zero;
   试试
    {
        tx.GetHandle（out txh）;
        if（txh == IntPtr.Zero）
           抛出新的例外（"CopyFileTransacted：无法获得交易处理。"）;
$
        CopyFileFlags copyFileFlags = 0;
        if（！overwrite）
            copyFileFlags = CopyFileFlags.COPY_FILE_FAIL_IF_EXISTS;
        if（！CopyFileTransacted（src，dst，IntPtr.Zero，IntPtr.Zero，IntPtr.Zero，copyFileFlags，txh））
           抛出新的异常（string.Format（"无法将{0}复制到{1}。CopyFileTransacted（）失败：{2}"，
src，dst，Marshal.GetLastWin32Error（）））;
$
    }
   终于
    {
        if（txh！= IntPtr.Zero）
            CloseHandle（txh）;
    }
} b $ b}
void DoSomeTransactionalStuff()
{
if (Transaction.Current != null)
{
Ktm.IKernelTransaction tx = (Ktm.IKernelTransaction)TransactionInterop.GetDtcTransaction(Transaction.Current);
IntPtr txh = IntPtr.Zero;
try
{
tx.GetHandle(out txh);
if (txh == IntPtr.Zero)
throw new Exception("CopyFileTransacted: Could not get transaction handle.");
CopyFileFlags copyFileFlags = 0;
if (!overwrite)
copyFileFlags = CopyFileFlags.COPY_FILE_FAIL_IF_EXISTS;
if (!CopyFileTransacted(src, dst, IntPtr.Zero, IntPtr.Zero, IntPtr.Zero, copyFileFlags, txh))
throw new Exception(string.Format("Could not copy {0} to {1}. CopyFileTransacted() failed: {2}",
src, dst, Marshal.GetLastWin32Error()));
}
finally
{
if (txh != IntPtr.Zero)
CloseHandle(txh);
}
}
}
正如我所说，代码在我的大多数用户的计算机上运行良好。这不是超时问题，因为DoSomeTransactionalStuff（）在创建事务后立即运行，并且日志中没有延迟。
As I said, the code works perfectly on most of my users' computers. This is not a timeout issue since DoSomeTransactionalStuff() runs right after the transaction is created and there's no delay in the log.

推荐答案
嗨Soren，
Hi Soren,
发生这种情况时，您是否在事件日志中收到任何事件？看起来可能存在向分布式事务提升的问题，这可能表明DTC配置不正确。
Do you get any events in the event log when this happens? It looks like there may be a problem promoting to a distributed transaction which could indicate DTC is not configured correctly.
