【中文标题】无法从您的配置中加载“paypal”部分

【英文标题】：Unable to load 'paypal' section from your config

【发布时间】：2015-08-12 14:46:57

【问题描述】：

我在使用 .NET 的 PayPal SDK 时遇到问题。我已经在 Web.config 中填写了我的设置，但是当我尝试使用 PayPal SDK 的 ConfigManager 来获取这些设置时，它会出现以下错误：

Unable to load 'paypal' section from *.config: An error occurred creating the configuration section handler for paypal: Exception has been thrown by the target of an invocation.

我希望有人以前可能遇到过这个问题，或者知道如何帮助我。

我也尝试使用 ConfigurationManager.GetSection("paypal") 手动加载 Web.config 设置，但也没有成功。

先谢谢了，希望你能帮助我！

我的 Web.config：

【问题讨论】：

您是否偶然安装了 .NET 4.6 RC？我们正在跟踪这个问题over on GitHub。

看起来我有 .NET 4.6，是的。我将重新安装它，然后改用 .NET 4.5.1 重试，谢谢！

感谢您的帮助，它解决了我的问题！

【参考方案1】：

按照 Jason Z 的建议卸载 .NET Framework 4.6 RC，解决了我的问题。

我确信在 PayPal SDK 的较新版本中，它可以与 .NET 4.6 一起使用，但不幸的是，目前还不能。

在安装 PayPal SDK 1.4.2 而不是 1.4.3 时，它似乎也可以工作。
