                      How to extract variable from a class with multiple variables, within a list

                      Asked 2022-Apr-02 at 21:43

                      I'm trying to make this program work as a glossary where you're supposed to be able to add your words in two languages. When happy with the number of words you've added you press a button and you can test yourself on those words.

                      In doing this I eventually ended up making a custom class containing the word in both languages and if it had been used in the word-test before. Now I'm at a stop where I try to fill a textbox with the word from the class that is laying within the list and I can't figure out how to get the data out.

                      I've tried a bunch of stuff but being a newbie I just dig the hole further and further down and I just can't get up...

                      I will just answer the title’s question “How to extract variable from a class with multiple variables, within a list?” (I don’t like reading non-English code).

                      Let’s say you have a list:

                      var list = new List<MyClass>
                      { 
                          new MyClass { PropertyA = “A”, PropertyB = “B” },
                          new MyClass { PropertyA = “1”, PropertyB = “2” }
                      }
                      

                      First find the instance (of the class) that you need:

                      var obj = list.FirstOrDefault(x => x.PropertyA == “1”);
                      

                      Then get a member’s value:

                      if (obj != null)
                      {
                          var myVariable = obj.PropertyB;
                      }
                      

                      If you’re sure your search will find the object, then you can use First instead of FirstOrDefault (both are from the namespace System.Linq) and skip the null-check.

                      If you need a random element:

                      var random = new Random(); // random number generator
                      var randomElement = list[random.Next(list.Count)];
                      

                      Note about System.Random:

                      It is better to make one instance of the Random class and reuse that instead of using it once and creating a new instance for each random number, because if you instantiate the Random class, its first value (and the series of numbers that comes next) depends on the current DateTime (in .NET Framework) and if instantiated within a very small time span, those instances may give the same “random” value.
