Question

我有一个共同的网络项目，可以作为几个孩子的基础＆＃34;网络项目。是否可以在项目之间应用web.config转换/合并？让我们说结构看起来像这样：

base project
  - web.config

child project
  - web.config
    - transform.config

是否可以制作预构建事件或类似项，将基础项目web.config与子项目web.config合并？

Answer 1

您可以编辑为单独的文件（transform.config）^[1]，[2]和：

添加<appsettings>部分，并将您的数据添加为表单的键/值对：
<add key="xxx" value="xxxx" />
这就是创建包含设置的新app.config文件。

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <appSettings>
    <add key="Child1" value="Child1_Value" />
    <add key="Child2" value="Child2_Value" />
  </appSettings>
</configuration>

连接字符串^[3]：

也是如此

<connectionStrings>
    <add name="yourConnectionStringName" 
         connectionString="yourConnectionString" 
         providerName="System.Data.SqlClient"/>
</connectionStrings>

并使用configSource作为父文件：

<connectionStrings configSource="parentWeb.config"/>

我最近遇到了这种问题 - 虽然我试图在运行时以编程方式合并两个web.config文件。

以下代码部分工作，对于AppSettings和Settings部分（必须添加ConnectionStrings），对于构建时间，您可以将其包装在可执行文件中：

    protected void Application_BeginRequest(object sender, EventArgs e)
    {
        var p = Server.MapPath("~/Web.user.config");
        if (File.Exists(p))
        {
            var fileMap = new ConfigurationFileMap(p); //Path to your config file
            var userConfig = ConfigurationManager.OpenMappedMachineConfiguration(fileMap);

            var globalConfig = WebConfigurationManager.OpenWebConfiguration("~/");
            var globalGroups = globalConfig.SectionGroups.Cast<ConfigurationSectionGroup>().ToList();

            CopySections(userConfig.Sections.Cast<ConfigurationSection>(), globalConfig.Sections.Cast<ConfigurationSection>());

            foreach (ConfigurationSectionGroup userGroup in userConfig.SectionGroups)
            {
                var globalGroup =  globalGroups.SingleOrDefault(g => g.SectionGroupName == userGroup.SectionGroupName);
                if (globalGroup != null)
                {
                    CopySections(userGroup.Sections.Cast<ConfigurationSection>(), globalGroup.Sections.Cast<ConfigurationSection>());
                }
            }

            globalConfig.Save();

        }
    }

    private void CopySections(IEnumerable<ConfigurationSection> source, IEnumerable<ConfigurationSection> target)
    {
        foreach (var sourceSection in source)
        {
            var targetSection = target.SingleOrDefault(s => s.SectionInformation.SectionName == sourceSection.SectionInformation.SectionName);
            if (targetSection != null)
            {
                var targetAppSettings = targetSection as AppSettingsSection;
                if (targetAppSettings != null)
                {
                    var sourceAppSettings = (AppSettingsSection) sourceSection;
                    foreach (KeyValueConfigurationElement keyValue in sourceAppSettings.Settings)
                    {
                        var targetSettings = targetAppSettings.Settings;

                        if (targetSettings.AllKeys.Any(k => k == keyValue.Key))
                        {
                            targetSettings.Remove(keyValue.Key);
                        }

                        targetSettings.Add(keyValue);
                    }
                }

                var targetClientSettings = targetSection as ClientSettingsSection;
                if (targetClientSettings != null)
                {
                    var sourceClientSettings = (ClientSettingsSection) sourceSection;
                    foreach (SettingElement keyValue in sourceClientSettings.Settings)
                    {
                        var targetSettings = targetClientSettings.Settings;
                        var existingSetting = targetSettings.Cast<SettingElement>().SingleOrDefault(e => e.Name == keyValue.Name);
                        if (existingSetting != null)
                        {
                            existingSetting.Value = keyValue.Value;
                        }
                    }
                }
            }
        }
    }
