windows forms, c# Passing values depending on the label chosen-CodePudding

I have a small game, this game have 5 diferent window forms, each window have diferent designs.

First: Welcome page, with play and rules Second: Level choice third: Actuall game fourth: Store to buy gadgets

I use this to open the new window and close the previous one

 FormMain formMain = new FormMain();
            formMain.Show();
            this.Hide();
        }

How can I pass variables to the new page, in both cases, the form sending and the form receiving. I tried this

formMain.Show(x, y);

But the show class implies other stuff.

My point is:

1 - depending on the label shosen with the level (1, 2, 3, 4, 5), I pass diferent values to the enemies, so I don´t have to create one form to each level.

2 - Choosing gadgets in the store passes to the game form to increase the player win.

There are tons of options but ill list a few:

1 passing data via the constructor of the Form/Class

public ClassName(int var1, int var2)
{
    //do something with var1 and var2
}

this might not be the best option if you want to do some animation with the passed data.

2 setting public variables after the class were created

public class ClassName()
{
    public int var1, var2;
}

elsewhere in code

ClassName clObject = new ClassName();
clObject.var1 = 1;
clObject.var2 = 2;
clObject.Show();

3 calling a method to pass the data

public class ClassName()
{
    private int var1, var2;
    public void DoTheThing(int var1, int var2)
    {
         //do something with the data
    }
}

elsewhere in code

ClassName clObject = new ClassName();
clObject.Show();
clObject.DoTheThing(1,2);

You can create an instance of the second form and access the public methods easily. I leave an example below.

// Click Event On First(Main) Form
private void ParameterSelect_Click(object? sender, EventArgs e)
        {
            try
            {
                    string value = "Test";
                    var secondFormInstance = new SecondForm();             
                    var result = secondFormInstance.SwitchExampleMethod(value);
                    if (result != null)
                    {
                        Console.WriteLine($"{result}");
                    }
                }
            }
            catch (Exception ex)
            {
                Log.Error($"Error while click event. Error: {ex.Message}");
            }
        }
// Second Form Method
public string SwitchExampleMethod(string value)
        {
            try
            {
                switch (value)
                {
                    case "Test":
                    case "Test1":
                    case "Test2":
                    case "Test3":
                        return "This value string for just a Test.";
                    case "Insane":
                    case "Wow":
                        return "This is amazing string text.";
                    default:
                        return "This is default string text.";
                }
            }
            catch (Exception ex)
            {
                Log.Error($"Error on switch. Error : {ex.Message}");
                return $"Error on switch. Error : {ex.Message}";
            }
        }
