我正在尝试在Winforms的表单加载事件中执行以下代码
MessageBox.Show(IPAddress.Parse("127.0.0.1").ToString());
在除Windows 8.1和Windows Server 2012之外的所有操作系统中，它的工作和弹出127.0.0.1。
在Windows 8.1上，它给出了以下错误
Error - The configuration section cannot contain a CDATA or text element. (C:\Program Files\eRS\Test.exe.Config line 3).

以下是我的app.config文件内容

从我可以看到你粘贴的app.config文件设置不正确。
您需要使用appSettings而不是<appSettings>正确打开appSettings>部分
然后你需要把
wwgp89LZ6RQNuYqA4QW49%2b54BdPvtS7WTpSIbQD39tBU8g6XgzuTvCbTL%2feaONiaI6S9c0rNsbbJRqjiW4pfjcndQF8Ol%2fxBWbT1ae0HhxAfoq1ZeF9FTq9KD%2bu1fi1QgFqPhbnM3VJMBGMx4QIBRTHQcQpcEsi9xjkSQ1AT4dt5qWAbfonvvHc1HqCtkoAyB8I9PG7HK6l844sCWVqRrUh8%2biICB0K2i1lJkwmlwhPoEqvW%2bHaXuSit1rCYasIn%2balIQ8wVyW8H5y8aNNzWWfEsYJSID%2bI2b379DiyENBLnacTAQ%3d%3d
在键/值对内部，如下所示：
<appSettings>
<add key="keynamehere" value="wwgp89LZ6RQNuYqA4QW49%2b54BdPvtS7WTpSIbQD39tBU8g6XgzuTvCbTL%2feaONiaI6S9c0rNsbbJRqjiW4pfjcndQF8Ol%2fxBWbT1ae0HhxAfoq1ZeF9FTq9KD%2bu1fi1QgFqPhbnM3VJMBGMx4QIBRTHQcQpcEsi9xjkSQ1AT4dt5qWAbfonvvHc1HqCtkoAyB8I9PG7HK6l844sCWVqRrUh8%2biICB0K2i1lJkwmlwhPoEqvW%2bHaXuSit1rCYasIn%2balIQ8wVyW8H5y8aNNzWWfEsYJSID%2bI2b379DiyENBLnacTAQ%3d%3d" />
</appSettings>
