我正在使用 app.config 文件从中读取数据..我正在加载 app.config 文件:

I am using app.config file to read data from it.. I am loading the app.config file as:

string app_path = HttpContext.Current.Server.MapPath("app.config");

推荐答案

在 ASP.NET 应用程序中，默认配置文件名为 web.config.这是您可能应该遵守的约定，它允许您轻松使用 ConfigurationManager 访问配置设置.

In ASP.NET applications, the default configuration file is named web.config. This is a convention you should probably stick to, that allows you to easily use the ConfigurationManager to access configuration settings.

我建议看看 http://en.wikipedia.org/wiki/Web.config 作为了解 ASP.NET 域中基本 .NET 应用程序配置的来龙去脉的起点.

I suggest having a look at http://en.wikipedia.org/wiki/Web.config as a starting point to learn the ins and outs of basic .NET application configuration in the ASP.NET domain.

您可以通过设置要覆盖的配置部分的 file 属性将配置文件链接在一起:http://www.codeproject.com/KB/dotnet/appsettings_fileattribute.aspx

You can link configuration files together, by setting the file attribute of configuration sections you want to override: http://www.codeproject.com/KB/dotnet/appsettings_fileattribute.aspx
