1. Add a new configuration node under appsetting:

"Keystrings": {    "key": "abc",    "value": "Test"  },

2. New class file KeyStrings.cs

public class keystrings{public  string Key{get;set} public  string Value{get;set;}    

3. Add the class and interface file to read the configuration file Keyreposiroty.cs,ikeyrepository.cs

public class keyreposiroty:ikeyreposiroty{  protected readonly   keystrings _keystrings;  Public Keyreposiroty (ioptions<keystrings> keystrings) {    _keystrings=keystrings  } public  virtual Keystrings mykeystrings        {            get            {                               return _keystrings;        }}}

　　

public interface ikeyreposiroty{   keystrings mykeystrings{get;}               

　　

4. New extension method

public static Iservicecollection getkeystring (this iservicecollection services, iconfigurationsection configuration) c15/>{                      Services. configure<keystrings> (configuration);            Services. Addsingleton<ikeyrepository,keyrepository> (); Class injection when there is no interface: services. Addsingleton<keyrepository> ();

return services;
}

5. Calling the extension method for dependency injection in startup

public void Configureservices (Iservicecollection services) {         
    

}

6. You can now access the configuration node information in the configuration file via the Ikeyrepository mykeystrings
