我怎么能告诉亚音速2使用不同的config文件？

问题描述

我使用的亚音速2从一个项目中，我想从指定默认的App.config不同的config文件。我怎么能告诉亚音速使用特定的配置文件？

I'm using SubSonic 2 from within a project and I'd like to specify a different .config file from the default App.config. How can I tell SubSonic to use a specific config file?

推荐答案

看来，你可以通过设置亚音速对象的两个属性做到这一点： DataService.ConfigSection 和 DataProvider.DefaultConnectionString 。一旦这些都设置亚音速不会尝试查找默认应用程序配置文件，它只会使用你给它的细节。

It appears that you can do this by setting two properties of SubSonic objects: DataService.ConfigSection and DataProvider.DefaultConnectionString. Once those are set SubSonic won't try to look for the default application configuration file, it'll just use the details you've given it.

例如：

        // Part 1: set the config section:
        string configPath = Assembly.GetExecutingAssembly().Location + ".config";
        ExeConfigurationFileMap execfg = new ExeConfigurationFileMap();
        execfg.ExeConfigFilename = configPath;
        Configuration configuration = ConfigurationManager.OpenMappedExeConfiguration(execfg, ConfigurationUserLevel.None);
        DataService.ConfigSection = (SubSonicSection)configuration.GetSection(ConfigurationSectionName.SUB_SONIC_SERVICE);

        // Part 2: set the connection string
        string connectionString = configuration.ConnectionStrings.ConnectionStrings["xLocal"].ConnectionString;
        DataProvider provider = DataService.Provider;
        provider.DefaultConnectionString = connectionString;

这似乎运作良好，但我有时会遇到长时间的延迟二号到最后一行的DataProvider提供商= DataService.Provider; 。我不知道这是做什么，我在这里做什么，或者它是一个大会装载问题。我记录在这里另一个问题这个问题：Call以System.Web.Configuration.ProvidersHelper.InstantiateProviders考虑年龄和年龄（从亚音速）

This appears to work well, however I am sometimes experiencing a long delay on the 2nd to last line DataProvider provider = DataService.Provider;. I'm not sure if this is to do with what I'm doing here or it's a general assembly-loading problem. I've documented this problem in another question here: Call to System.Web.Configuration.ProvidersHelper.InstantiateProviders taking ages and ages (from SubSonic)
