[Exception] 当前 TransactionScope 已完成

转自  http://www.cnblogs.com/loafer/archive/2010/06/03/TransactionScopeComplete.html

捕获异常的时候 经常会碰到这个异常报告

导致原因

//正确代码
using (TransactionScope ts = new TransactionScope(TransactionScopeOption.Required))
{
//xxx();
ts.Complete();

}
DoSomething();

 
//错误代码
using (TransactionScope ts = new TransactionScope(TransactionScopeOption.Required))
{
  //xxx();
  ts.Complete();
  DoSomething();
}

主要是 在using TransactionScope的ts.Complete();之后不要写任何代码
