.NET 3.5 - 配置系统无法初始化异常

Question

在我的winform应用程序中,我正在尝试添加userSetting,尽管appSettings也出现了错误.当添加设置时,我得到一个抛出的异常,说:"配置系统无法初始化",内部异常"无法识别的配置部分userSetting"

例外细节:

Answer 1

我有一些用户设置,然后删除所有这些设置并开始看到此异常 - 但仅在运行应用程序时没有调试.调试应用程序时它工作正常.原因是用户级设置在本地应用程序数据文件夹中"缓存",实际上不会从MYAPP.exe.config中读取.所以我做的是去C:\ Users\MYUSERNAME\AppData\Local\MYCOMPANY\MYAPP.exe_Url_longnastyhash9982749827349879\1.0.0.0\user.config(这是在Win7上,路径依赖于操作系统)并删除该文件夹(使用完全长的哈希).例外消失了.顺便说一句,根据您的设置设置,此user.config文件可能位于\ AppData\Local或\ AppData\Roaming下.

Answer 2

尝试检查app.config(myapp.exe.config一旦部署)文件是否存在并且位于顶部(可能还有其他位)

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<configSections>
<sectionGroup name="userSettings"
    type="System.Configuration.UserSettingsGroup, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" >
</sectionGroup>

Answer 3

当我编写App.Config(愚蠢)时,我收到此错误,如下所示.

<?xml version="1.0" encoding="utf-8" ?>
<configuration>

<!--List of XMLFiles Begins -->
    <add key="ConfigFileEnvironment" value="C:\Program Files\MyProduct\Config\Environment.xml" />
<!--List of XMLFiles Ends -->

</configuration>

请注意,没有appSettings？我曾经经常做这个错误......
