在C#中捕捉SOAP，在DLL中

我正在构建一个DLL，它应该被我正在构建的其他应用程序使用。 DLL功能的一部分是记录所有SOAP事务

我发现了关于如何在C#中捕获SOAP事务的这种解释。

我的问题是需要将以下内容添加到app.config（链接页面的末尾）

我不希望它成为所有使用我的DLL将其添加到app.config的用户的要求

在加载DLL时，有没有一种方法可以在运行时执行此操作？

我在MSDN论坛上发现了一个类似的问题：

谢谢，这正是我想要的。第二步，我不知道这是不是你自己试过的东西。但是如果你知道了，你知道这是不是线程安全的吗。也就是说，如果我有两个线程，并且我在其中一个线程中运行这个“寄存器”。他会捕获第二根线制成的肥皂吗？我认为它不是线程安全的。您可以将其与

lock（obj）{…}

同步，或者在启动线程之前执行此操作。
