Iteration of checkboxes to pdf c# class

Question

so i had some wonderful help with the previous iteration of this that worked great!

I have tried modifying my code with the info at Get property value from string using reflection in C#

but either i am getting it wrong or my class is setup in a way as to not work with that method.

i used the code

foreach (var checkbox in this.Controls.OfType<CheckBox>())
        {
            pdfFormFields.SetField(checkbox.Name, checkbox.Checked ? "Yes" : "No");
        }

and it worked great now ive been told to use a class to make it more universtal my class is

public class Entries
{
    ///Some other Values
    public string ColourW;
    public bool CheckBox1 { get; set; }
    public bool CheckBox2 { get; set; }
    public bool CheckBox3 { get; set; }
    public bool CheckBox4 { get; set; }
    public bool CheckBox5 { get; set; }
    public bool CheckBox6 { get; set; }
    public bool CheckBox7 { get; set; }
    public bool CheckBox8 { get; set; }
    public bool CheckBox9 { get; set; }
}

I need a foreach statement like the above but to set the info to the data in class something like this, however i get a identifier expected error.

foreach (var checkbox in this.Controls.OfType<CheckBox>())
        {
            Data.(checkbox.Name, checkbox.Checked ? "Yes" : "No");
        }

Help is appreciated, help with an explanation of how the code work is greatly appreciated!

sorry in advance, Im a hardware guy!

EDIT

So solved majority of the issues thanks to @Furkan Kambay managed to get check-boxes into and out of class but for some reason the check-boxes on the PDF will not set to the same state?

Longer explanation, class is set up form works fine all combo boxes and text fields when called pdfFormFileds("Textx", Entries.ColourW); work fine however the PDF check boxes do not change state when using the code, i am using iTextSharp library

foreach (var box in Entries.CheckBoxes) 
            {
                pdfFormFields.SetField(box.Key, box.Value ? "Yes" : "No");
             }

Setup for PDF

string pdfTemplate = @"C:\Testing Templates\Pre V-Change Head Test Certificate Template.pdf";
            string newFile = @"c:\temp\PDF\" + Entries.SerialNumber + " " + Entries.TestedWithCal + " Pre V-Change Head Test Certificate.pdf";
            string Created;

            PdfReader pdfReader = new PdfReader(pdfTemplate);
            PdfStamper pdfStamper = new PdfStamper(pdfReader, new FileStream(newFile, FileMode.Create));
            AcroFields pdfFormFields = pdfStamper.AcroFields;

Answer 1

Edit your class to be like this:

public static class Entries
{
    // ... all the other fields with static keyword
    public static string ColourLRB;
    public static string ColourW;
    public static Dictionary<string, bool> CheckBoxes { get; } = new Dictionary<string, bool>(); // no set, so you can only modify this. 
}

And then:

foreach (var checkbox in this.Controls.OfType<CheckBox>())
{
    CheckBoxes[checkbox.Name] = checkbox.Checked;
}

I think you can improve the foreach statement with a LINQ query mapping CheckBoxes to KeyValuePairs. If you want, I can edit the answer.

edit, mapping with LINQ: (replaces the whole foreach)

var boxes = this.Controls.OfType<CheckBox>();
CheckBoxes = boxes.ToDictionary(b => b.Name, b => b.Checked);

edit2, setting again

foreach(var box in Entries.CheckBoxes) // this is using static. For Singleton it would be "var box in Entries.Instance.CheckBoxes"
{
    pdfFormFields.SetField(box.Key, box.Value ? "Yes" : "No");
}

Answer 2

var entries = new Entries(); // looks to me like this class and its members should be static, no?
foreach (var checkbox in this.Controls.OfType<CheckBox>())
{
    if(checkbox.Name == "CheckBox1") entries.CheckBox1 = checkbox.Checked;
    else if(checkbox.Name == "CheckBox2") entries.CheckBox2 = checkbox.Checked;
    else if(checkbox.Name == "CheckBox3") entries.CheckBox3 = checkbox.Checked;
    // ...
}
