无法转换为我的自定义 ConfigurationSection
我正在尝试读取这样的配置文件：
var dllPath = System.IO.Path.GetDirectoryName(System.Reflection.Assembly.
GetExecutingAssembly().GetName().CodeBase);
dllPath = dllPath.Replace("file:\\", string.Empty);
var configPath = string.Format(@"{0}\..\contentFolders.config", dllPath);
var fileMap = new ExeConfigurationFileMap() {ExeConfigFilename = configPath};
var config = ConfigurationManager.OpenMappedExeConfiguration(fileMap,
ConfigurationUserLevel.None);
var contentFolderConfig =
(ContentFolderSettings)config.GetSection("contentFolderConfiguration");
我在 Corp.Common 项目中定义了 ContentFolderSettings，并且它继承自 ConfigurationSection。以下是 contentFolders.config 的内容：
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<section name="contentFolderConfiguration"
type="Corp.Common.ContentFolderSettings, Corp.Common"
requirePermission="false"/>
<contentFolderConfiguration>
<contentFolders>
<contentFolder key="ImagesFolder" path="content\images"/>
<contentFolder key="CssFolder" path="content\css"/>
...
</contentFolders>
</contentFolderConfiguration>
</configuration>
但是调用 config.GetSection() 的行抛出 InvalidCastException：
Unable to cast object of type 'System.Configuration.DefaultSection' to type
'Corp.Common.ContentFolderSettings'.
I'm trying to read a config file like this:
var dllPath = System.IO.Path.GetDirectoryName(System.Reflection.Assembly.
GetExecutingAssembly().GetName().CodeBase);
dllPath = dllPath.Replace("file:\\", string.Empty);
var configPath = string.Format(@"{0}\..\contentFolders.config", dllPath);
var fileMap = new ExeConfigurationFileMap() {ExeConfigFilename = configPath};
var config = ConfigurationManager.OpenMappedExeConfiguration(fileMap,
ConfigurationUserLevel.None);
var contentFolderConfig =
(ContentFolderSettings)config.GetSection("contentFolderConfiguration");
I have ContentFolderSettings defined in the Corp.Common project and it inherits from ConfigurationSection. Here is the contents of contentFolders.config:
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<section name="contentFolderConfiguration"
type="Corp.Common.ContentFolderSettings, Corp.Common"
requirePermission="false"/>
<contentFolderConfiguration>
<contentFolders>
<contentFolder key="ImagesFolder" path="content\images"/>
<contentFolder key="CssFolder" path="content\css"/>
...
</contentFolders>
</contentFolderConfiguration>
</configuration>
But the line calling config.GetSection() is throwing InvalidCastException on:
Unable to cast object of type 'System.Configuration.DefaultSection' to type
'Corp.Common.ContentFolderSettings'.
