Hi, im working with a WPF application and trying to do like a candy calculator. I can make everything and put in values, but now im trying to sort out the sorting of the list after a property. So i have done this:

 public class Person
 {
         public int Age { get; set; }
         public string FirstName { get; set; }
         public string LastName { get; set; }
         public int Candies { get; set; }

     public List<Person> PeopleList { get; set; }


     public override string ToString()
     {
         return $"{FirstName} {LastName}, Age: {Age}, Candies {Candies}";
     }

     public void DistrubuteCandyByAge()
     {

          PeopleList = PeopleList.OrderBy(x => x.Age).ToList();
     }

     public void DistrubuteCandyByFirstname()
     {
          PeopleList = PeopleList.OrderBy(x => x.FirstName).ToList();

     }
     public void DistrubuteCandyByLastName()
     {
          PeopleList = PeopleList.OrderBy(x => x.LastName).ToList();
     }

 public class Person
 {
         public int Age { get; set; }
         public string FirstName { get; set; }
         public string LastName { get; set; }
         public int Candies { get; set; }

     public List<Person> PeopleList { get; set; }


     public override string ToString()
     {
         return $"{FirstName} {LastName}, Age: {Age}, Candies {Candies}";
     }

     public void DistrubuteCandyByAge()
     {

          PeopleList = PeopleList.OrderBy(x => x.Age).ToList();
     }

     public void DistrubuteCandyByFirstname()
     {
          PeopleList = PeopleList.OrderBy(x => x.FirstName).ToList();

     }
     public void DistrubuteCandyByLastName()
     {
          PeopleList = PeopleList.OrderBy(x => x.LastName).ToList();
     }

✅ Combobox writes out collection instead of the values

Hi im working in a WPF application for a university project thats based on Harry Potter. So i have built Hogwarts, and then put in the different houses, Gryffendor and so and so in different classes and built them after a house class to follow the same criteria. So the story is that you supposed to put in a password, and then fill in in a combobox which house the password is for. But when I do the combobox like bellow it just says collection, and not the differnt houses, why? Also added more code into here: https://paste.mod.gg/

✅ Methods

Hi, i need help building a method to see if a textbox contains digits or letters. The assignment is to put in the year you are born and then give back how old you are. The tricky part for me is to build a method that will catch if you put letters in your textbox and not break down. Im not allowed to use any built in methods like tryParse och try and catch. ```cs private void Button_Click(object sender, RoutedEventArgs e) { string yearBorn = TxtYearBorn.Text; bool istrueornot = TryifStringisNumber(yearBorn);
if (istrueornot == false) { MessageBox.Show("Du får bara skriva in siffror"); } else if (istrueornot == true) { int integerYearBorn = int.Parse(yearBorn); int yearBornResult = Age(integerYearBorn); MessageBox.Show($"You are {yearBornResult} years old"); } } public bool TryifStringisNumber(string yearborn) { for (int i = 0; i < yearborn.Length; i++) { if (i <= 0 ) { return false; } else {
return true; } } return false; } private int Age(int yearOfBirth) { if (yearOfBirth >= 0) { return -1; } else { int currentyear = DateTime.Now.Year; return currentyear - yearOfBirth; } }
} }
