How to load appsetting.json section into Dictionary in .NET Core?

Question

I am familiar w/ loading an appsettings.json section into a strongly typed object in .NET Core startup.cs. For example:

public class CustomSection 
{
   publ         


        

Answer 1

For others who want to convert it to a Dictionary,

sample section inside appsettings.json

"MailSettings": {
    "Server": "http://mail.mydomain.com"        
    "Port": "25",
    "From": "info@mydomain.com"
 }

Following code should be put inside the Startup file > ConfigureServices method:

public static Dictionary MailSettings { get; private set; }

public void ConfigureServices(IServiceCollection services)
{
    //ConfigureServices code......

    MailSettings = Configuration.GetSection("MailSettings").GetChildren()
                  .ToDictionary(x => x.Key, x => x.Value);
}

Now you can access the dictionary from anywhere like:

string mailServer = Startup.MailSettings["Server"];

One downside is that all values will be retrieved as strings, if you try any other type the value will be null.
