I’ve been using the SendGrid API for a project and I was trying to be lazy and read multiple email addresses to send to from a single parameter in appsettings.json with the email addresses separated by a semicolon. Strangely this only sends to the first email in the string so I needed to do a little more work and store the emails in an array in appsettings.json and to read this into a list and then loop through it adding each address individually.

{ "Email": { "ToEmails": [ "[email protected]", "[email protected]", "[email protected]" ] } } // Build configuration IConfigurationRoot _config = new ConfigurationBuilder() .SetBasePath(Directory.GetParent(AppContext.BaseDirectory).FullName) .AddJsonFile("appsettings.json", false) .Build(); List<string> emailTo = _config.GetSection("Email:ToEmails").Get<List<string>>(); foreach(string email in emailTo) { sendGridMessage.AddTo(newEmailAddress(email)); }

If you are aiming to use this in a console application then you’ll need to install the following NuGet packages.

Can you help me to mock this “_config.GetSection(“Email:ToEmails”).Get<List>();” with moq for unit testing? I am having hard time to figure this out
