Is TMemIniFile thread-safe?

推荐答案

据我所知TMemIniFile（以及任何其他TCustomIniFile后代）不是线程安全的。您需要将其包装到关键部分。

As far as I know TMemIniFile (and any other TCustomIniFile descendants) is not thread-safe. You will need to wrap it into a critical section.

在此链接，您可以找到线程安全的TCustomIniFile的实现（理论上由 TeamB ，尽管我不能保证）。

In this link you can find an implementation of a thread-safe TCustomIniFile (theoretically programmed by Peter Below of TeamB though I can not assure it).

Embarcadero论坛上还讨论了TMemIniFile的线程安全性此处。他们谈论组件的C ++版本。

There is also a discussion in the Embarcadero forums about the thread-safety of TMemIniFile here. They speak about the C++ version of the component.

您还可以在MSDN中找到有关错误消息来源的讨论此处。它有点长，但总体结论是有2个exe试图访问同一文件。您可以在此处找到其他讨论。

You can also find a discussion in MSDN regarding the origin of your error message here. It is a bit long but the general conclussion is that there are 2 exes trying to acces the same file. You can find another discussion on the subject here.
