My appsettings json file

       {
         "StudentBirthdays": [
                { "Anne": "01/11/2000"},
                { "Peter": "29/07/2001"},
                { "Jane": "15/10/2001"},
                { "John": "Not Mentioned"}
            ]
        }

I have a seperate config class.

public string GetConfigValue(string key)
{
    var value = _configuration["AppSettings:"   key];
    return !string.IsNullOrEmpty(value) ? Convert.ToString(value) : string.Empty;
}

What I have tried is,

 list= _configHelper.GetConfigValue("StudentBirthdays");

For the above I dont get the values.

How can I read the values(I want to read the name of the student and his birthday seperatly).

Any help is apreciated

CodePudding user response：

You can obtain the birthdays using the following code:

// get the section that holds the birthdays
var studentBirthdaysSection = _configuration.GetSection("StudentBirthdays");

// iterate through each child object of StudentBirthdays
foreach (var studentBirthdayObject in studentBirthdaysSection.GetChildren())
{
    // your format is a bit weird here where each birthday is a key:value pair,
    // rather than something like { "name": "Anne", "birthday": "01/11/2000" }
    // so we need to get the children and take the first one
    var kv = studentBirthdayObject.GetChildren().First();
    string studentName = kv.Key;
    string studentBirthday = kv.Value;
    Console.WriteLine("{0} - {1}", studentName, studentBirthday);
}

Try it online

try this

using System.Linq;

public List<Student> GetStudentsFromConfig()
{
    return  _configuration
    .GetSection("StudentBirthdays")
    .Get<Dictionary<string, string>[]>()
    .SelectMany(i => i)
    .Select(ie => new Student {Name=ie.Key, DOB=ie.Value})
    .ToList();
}

test

items= _configHelper.GetStudentsFromConfig();

foreach (var item in items) Console.WriteLine($"Name: {item.Name} , DOB: {item.DOB} ");

result

Name: Anne , DOB: 01/11/2000 
Name: Peter , DOB: 29/07/2001 
Name: Jane , DOB: 15/10/2001 
Name: John , DOB: Not Mentioned 

class

public class Student
{
    public string Name { get; set; }
    public string DOB { get; set; }
}

Try this: Create Model/Class like below:

public class StudentBirthday
{
   String Name,
   String Birthday
}

Then access values like this :

List<StudentBirthday StudentBirthdays = 
   _config.GetSection("Main:StudentBirthdays").Get<List<StudentBirthday();
