如何解决即使有意中止，“交易已中止”也会被捕获
关于我如何使用 TransactionScope 的一些上下文，如果三个数据库的查询中的任何一个捕获到错误，目前在程序中，我做了它以便 TransactionScope 将 { {1}} 导致没有数据通过的所有内容。这部分程序运行良好。
另一个背景是我使用的框架是 ASP.NET Boilerplate。
由于保密原因，下面将包含代码减去一些细节。
dispose现在的问题是，我使用的框架会将 public CUDResult TriTransaction(TransactItem[] item)
{
CUDResult result = new CUDResult();
using (TransactionScope ts = new TransactionScope())
{
try
{
result = InsertItem(item);
if (result.success == false)
return result;
ts.Complete();
}
catch (Exception)
{
ts.dispose();
return result;
}
}
return result;
}
视为服务器错误，并且始终会针对所述服务器错误 dispose 返回已修复的错误消息。
尽管后端按照我希望的方式工作，但我更希望 An internal error occurred during your request 不会被捕获为服务器错误并导致前端显示上述错误消息。
下面将包含记录的错误消息。
dispose我怀疑这可能不仅仅是 ERROR 2021-04-26 14:34:04,260 [::1] [Chrome90] [20] Abp.WebApi.ExceptionHandling.AbpApiExceptionFilterattribute - The transaction has aborted.

被捕获为错误的事实，也可能完全是其他原因，但我对此没有足够的了解，想知道是否有任何错误解决前端总是显示 dispose 错误消息的问题的方法，每当有意处理事务时。
解决方法
您的问题是您调用 Dispose 两次，您永远不需要手动调用 Dispose，这就是 using 语句的用途。 using (...) 基本上只是 try/finally 块的一些 syntactic sugar。所以这个：
using (var foo = new Foo())
{
foo.SayHello();
}
被编译为
Foo foo = new Foo();
try
{
foo.SayHello();
}
finally
{
if (foo != null)
{
((IDisposable)foo).Dispose();
}
}
意味着你的代码被编译为
CUDResult result = new CUDResult();
TransactionScope ts = new TransactionScope();
try
{
try
{
result = InsertItem(item);
if (!result.success) // instead of result.success == false
return result;
ts.Complete();
}
catch (Exception)
{
ts.Dispose();
return result;
}
}
finally
{
if (ts != null)
{
((IDisposable)ts).Dispose();
}
}
return result;
很明显，当捕获到异常时，您将处理 ts 两次
