Pass value from Dialog Form to another Form in C#

Question

I have a C# windows form application. I have a form already opened and I need to open another form as dialog. For example, I have a form "Sell Cars", inside that form I have the fields related to the car (license, model, year, etc.) and a button to open a dialog box with the list of cars to be sold. The user selects one from the list and after that I need to copy all values of the selected car into the main form and close the dialog form.

What is the best way to do it?

You can access and set variable of any form opened by your main form.

main.cs

string result = "";
using(SecondForm secondForm = new SecondForm()) 
{
    if(secondForm.ShowDialog() == DialogResult.OK) 
    {
        result = secondForm.carName;
    }
}

SecondForm.cs

public partial class SecondForm
{
    public string carName;
    public SecondForm(){
        carName = "honda";
    }
}

I need to pass info from SecondForm to main. The SecondForm should be the dialog – tbag Nov 07 '21 at 19:50
Yeah, so in `main` you'd go `mySecondFormInstance.Car` – ScottishTapWater Nov 07 '21 at 19:50
Not sure I follow, sorry. When the user selects the car from dialog, I suppose to dispose that form – tbag Nov 07 '21 at 19:52
I updated the code. Basically the same concept. You can access form 1 from form 2, and vice versa – Jay Nov 07 '21 at 19:53
got it, thank you so much – tbag Nov 07 '21 at 19:55
