特定于装配的设置无法在运行时加载 [英] Assembly specific settings not loading at runtime

问题描述

我正在开发.NET 3.5 Windows Forms应用程序.我有两个项目，UI和一个库.

I am developing a .NET 3.5 Windows Forms app. I have two projects, the UI and a Library.

UI通常使用强类型设置，这些设置通常存储在app.config文件中.我使用UI.Properties.Settings类(由Visual Studio生成)阅读它们.

UI uses strongly typed settings that are stored, as usually, in the app.config file. I read them using UI.Properties.Settings class (generated by Visual Studio).

库使用其自己的强类型设置(转储到Library.config文件中的Settings.settings文件).

Library uses its own strongly typed Settings (the Settings.settings file that is dumped into Library.config file).

在运行时，库设置不会从Library.config文件中重新加载.运行时仅读取UI.config文件.因此，我坚持使用库"程序集中的默认设置，并且无法在部署后提供值.

At runtime, Library settings will not reload from the Library.config file. Only UI.config file is read by the runtime. So I am stuck with default settings in Library assembly, and cannot provide values after deployment.

总结:对于不是主要可执行文件的应用程序程序集，在程序集加载时不会读取设置.

To summarize: for an application assembly that is not the main executable, the settings are not read at assembly load time.

我知道我可以使用ConfigurationManager.AppSettings ["value"]，这将从默认的应用程序配置文件(UI.config)中读取，但是如果我要使用强类型的设置(使用Properties.Settings类读取)，该怎么办?

I know I can use ConfigurationManager.AppSettings["value"] and this will read from the default app config file (UI.config) but what can I do if I want strongly typed settings (read with Properties.Settings class)?

调用 Library.Properties.Settings.Default.Reload()不会执行此操作.

谢谢.

推荐答案

您需要做的是将您的库配置节合并到app.connfig.合并配置文件是通过首先在< configSections >中添加元素来完成的config元素，以标识config部分，然后在配置元素内添加config元素.

What you need to do is merge your library config sections to app.connfig. Merging config files is done by first adding elements inside the <configSections> config element, to identity the config section and then by adding the config elements inside the configuration element.

合并配置文件的示例:

应用配置:

<?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" >
            <section name="CA3.Settings" type="System.Configuration.ClientSettingsSection, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" allowExeDefinition="MachineToLocalUser" requirePermission="false" />
        </sectionGroup>
    </configSections>
    <userSettings>
        <CA3.Settings>
            <setting name="Setting" serializeAs="String">
                <value>2</value>
            </setting>
        </CA3.Settings>
    </userSettings>
</configuration>

库配置:

<?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" >
            <section name="CA3.Library" type="System.Configuration.ClientSettingsSection, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" allowExeDefinition="MachineToLocalUser" requirePermission="false" />
        </sectionGroup>
    </configSections>
    <userSettings>
        <CA3.Library>
            <setting name="Setting" serializeAs="String">
                <value>1</value>
            </setting>
        </CA3.Library>
    </userSettings>
</configuration>

包含库和应用程序配置的合并的app.config.

Merged app.config containing both library and app configuration.

<?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" >
            <section name="CA3.Settings" type="System.Configuration.ClientSettingsSection, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" allowExeDefinition="MachineToLocalUser" requirePermission="false" />
            <section name="CA3.Library" type="System.Configuration.ClientSettingsSection, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" allowExeDefinition="MachineToLocalUser" requirePermission="false" />
        </sectionGroup>
    </configSections>
    <userSettings>
        <CA3.Settings>
            <setting name="Setting" serializeAs="String">
                <value>2</value>
            </setting>
        </CA3.Settings>
        <CA3.Library>
            <setting name="Setting" serializeAs="String">
                <value>1</value>
            </setting>
        </CA3.Library>
    </userSettings>
</configuration>
