我正在构建一个DLL,应该由我正在构建的其他一些应用程序使用.
DLL功能的一部分是记录所有SOAP事务.

我已经找到了关于如何在C#中捕获SOAP事务的解释.

我的问题是它需要将以下内容添加到app.config(链接的页面末尾).
<system.web>
<webServices>
<soapExtensionTypes>
<add type="Encore.PayPal.Soap.TraceExtension,Encore.PayPal.Soap" priority="1" group="0" />
</soapExtensionTypes>
</webServices>
</system.web>
我不希望它是所有使用我的DLL将其添加到app.config的要求.
有没有办法在DLL加载时动态执行此操作？

我在MSDN论坛上发现了类似的问题：
