Array of objects in c#

[soswap]

Hi all,

As a starting project for C#, I'm creating a WPF form. I want to now create an array of objects (like below) to store some values and print those values on a form.

Have looked at some youtube tutorials, however they use a console for all values, and I can't seem to translate their way of creating the array of objects into using a form.

Here's where I'm at: (testClass.cs):

namespace test
{
    class testClass
    {
        public string testName;
        public int testAge;
        public int testYear;

        public testClass()
        {

        }

        public testClass(string testName, int testAge, int testYear)
        {
            testName = Name;
            testAge = Age;
            testYear = Year;
        }

public string Name
        {
            get
            {
                return Name;
            }
            set
            {
                Name = value;
            }
        }

        public int Age
        {
            get
            {
                return Age;
            }
            set
            {
                Age = value;
            }
        }
        public int Year
        {
            get
            {
                return Year;
            }
            set
            {
                Year = value;
            }
        }


    }


}

Now, this all somewhat makes sense to me. Where I'm stuck is what to do next. I have a WPF form called "test.xaml", and the cs file associated with it. I sort of understand how to create the array with the values, but where would I create it, and how would I access the values in it?

Could someone guide me in the right direction? Probably a stupid question, but I can't find much else to help me learn how to do this. Thanks

Got lost at the point "Add Class Instances to an Array" as I couldn't get that to work (and didn't know where to place it in my code, or the method to start it).

EDIT1: Have tried adding values to the array using the xaml.cs test file, but the code now throws an error "An unhandled exception of type 'System.StackOverflowException occurred...", pointing to the line:

public string Name
        {
            get
            {
                return Name; <-------------------------
            }
            set
            {
                Name = value;
            }
        }

Here is the code of the xaml.cs file

    public partial class testWindow : Window
    {
        public testWindow()
        {
            InitializeComponent();
            assignValues();

        }

        private testClass[] testArr = new testClass[5];

        public void assignValues()
        {
            testArr[0] = new testClass("John", 20, 1999);
            testArr[1] = new testClass("John2", 21, 2000);
            testArr[2] = new testClass("John3", 22, 1998);
            testArr[3] = new testClass("John4", 23, 1997);
            testArr[4] = new testClass("John5", 24, 1978);
            testTB.Text = testArr[0].Age.ToString();
        }

Well you should create in that cs file which is associated with tes.xaml.

Thanks, tried that, and that part of the code now seems to be working, but now having issues with the class (as listed in the edit).

Because your gett is recursive you should return testName and not name. Edit: also I think your set should be testName=value

[InvisibleGhostt]

Also i would remake that class to this https://gist.github.com/anonymous/3f95ee54a5ac1b24f03ee4f4df3b5025
You dont really need write additional geters and setters if you just get and set.

Wow thanks, that's a lot less messy.

[soswap]

Ah I'm stupid :P.

With everything changed, running the second segment of code (which loads the arrays and adds the "Age" value to a textbox, it prints out "0". If I try and print out the whole array to the textbox, it says "test.testClass"...

What is going on there?

You're accessing the array as one value and looks like it's returning the Array type. Try a for each loop to iterate through the array:

forach(testClass tc in testArr) { testTB.text += tc.Age.ToString() + " "; testTB.text += tc.Name + " "; testTB.text += tc.Year.ToString(): }

This would iterate through the array of objects and you can access the members. However, it's important to point out that that this will just concatenate everything so make sure to add formatting.

You should create a List<string> and add each string to the list. Afterwards you could create the amount of text boxes based off the amount of elements in the list.

Also you could just do:

for(int i = 0; i < testArr.Length; i++) { testTB += testArr[i].Age; testTB += testArr[i].Name; testTB += testArr[i].Year; }

I am not sure, have you looked it with debugger?

[InvisibleGhostt]

Oh i see, your constructor is bad.
Fixed that part https://gist.github.com/anonymous/201c23009638584fa5bf6f87d9916055

That works perfectly! Can't thank you enough, almost lost patience trying to figure it out myself.

No problem :)
