Reading a configuration file in ASP. NET 5

(This article also published in my public number "dotnet daily Essence article", Welcome to the right QR code to pay attention to. )

The infrastructure of the previous configuration file was discarded in ASP. NET 5, and a new configuration file system was introduced. The article recommended today is a brief introduction to this aspect.

Microsoft has introduced a new profile infrastructure in the upcoming cross-platform runtime, based on which it has never been so easy to read content from multiple configuration files.

This configuration system not only has a built-in configuration file that supports Json,xml and INI formats, it also supports reading content from environment variables. As follows:

var New Configuration ()                            . Addjsonfile ("config.json")                            . Addinifile ("config.ini")                            . Addxmlfile ("config+ +")                            . Addenvironmentvariables ();

To support JSON files, Microsoft.Framework.ConfigurationModel.Json namespaces must be introduced, XML files must be introduced, MICROSOFT.FRAMEWORK.CONFIGURATIONMODEL.XML should be imported, and INI files should be introduced MICR Osoft. Framework.configurationmodel.

For a JSON configuration file like this:

{    "Data": {"        defaultconnection": {             "ConnectionString": "server= ( LOCALDB) \\mssqllocaldb;database=dbname; Trusted_connection=true; Multipleactiveresultsets=true"        }}    }

Reading the content is simple:

var connectionString = Configuration. Get ("Data:DefaultConnection:ConnectionString");

"Read the original" can browse the original text (the original content is relatively simple, almost like this).
