将对象传递给新表单

我想做那样的事情：

的MainForm：

Car car = new Car(); //create new object Form form2 = new Form(car); //Create new form and pass the car that I've created a line before. form2.Show(); //Show the second Form 

窗体2：

 public Car(Car car) { InitializeComponent(); //here the car is visible, in private method below, for the button, I can't get to it. } private void button(object sender, EventArgs e) { car.maker = "VW" //update the information about the car. I can't make this line to work, variable "car" is unavailable here, how to get to it? this.Close(); //close second form } 

如何在form2中获取此对象并将其返回给MainForm，当我在form2中添加有关汽车的所有信息时？

Answer 1

在form2中创建一个属性

 public Car MyCar {get; set;} 

并设置此属性

 Car car = new Car(); //create new object Form form2 = new Form(); form2.MyCar=car; form2.ShowDialog(); // get car here again Car car2 =form2.MyCar;
