How do you transfer variables between forms in C#?

Question

I was just wondering exactly how you transfer string and integer variables between forms. Example on what I mean would be having the user input their name and age which would transfer and show in another form and have this be activated by a button.

Answer 2

You can achieve this by using Simple Events and delegate concept. Publish event from your Form 1 and you can subscribe that in your Form 2 page. Delegate will be act as a communication channel between Event and Event handler.

Answer 3

Use a Global static class for saving values. And just use the object of that class at the another location.And create new object of the class whenever the task is completed.

Answer 4

You could pass the values from the main form to the child form using public properties.

Something like

public partial class ParentForm : Form
{
    public ParentForm()
    {
        InitializeComponent();
    }
    private void button2_Click(object sender, EventArgs e)
    {
        ChildForm c = new ChildForm();
        c.StringValue = "TADA";
        c.IntValue = 42;
        c.Show();
    }
}


public partial class ChildForm : Form
{
    public string StringValue{get; set;}
    public int IntValue { get; set; }

    public ChildForm()
    {
        InitializeComponent();
    }
}
