. Netcore getting JSON file configuration content

The data configuration and content in the. Netcore uses a JSON file instead of an XML file from the previous framework, so how do you get the data in JSON? Here's how to get the JSON file in. NET Core.

Addjsonfile ("Jsonfile/class.json");            var config = builder. Build ();            String str = "class:" + config["Classnum"]+ "/";            Return Content ("class number =" +config["Classnum"]+ ", class name =" + config["ClassName"]+ "\ r"                + "Student name =" +config["students:0: Name "]+", student age = "+ config[" Students:0:age "]            );}}}
