将对象传递到不同的Windows窗体 [英] Passing object to different windows forms

问题描述

我想在获胜表格之间传递C＃对象。目前，我已经建立了一个基础项目来学习如何执行此任务，该项目由两种形式组成：form1和form2，以及一个名为class1.cs的类，该类包含get和set方法，用于设置在form1中输入值的字符串变量。 （应该从表格2中获取存储在class1对象中的值）

I want to pass a C# object between win forms. At the moment, I have setup a basic project to learn how to do this which consists of two forms - form1 and form2 and a class called class1.cs which contains get and set methods to set a string variable with a value entered in form1. (Form 2 is supposed to get the value stored in the class1 object)

如何从在form1中设置的对象中获取字符串值？我是否需要将其作为参数传递给form2？

How can I get the string value from the object that was set in form1? Do I need to pass it as a parameter to form2?

任何评论/帮助都会被赞赏！

Any comments/help will be appeciated!

谢谢，

编辑：这是我目前的代码：（form1.cs）

Here's the code I have at the moment: (form1.cs)

    private void button1_Click(object sender, EventArgs e)
    {
        this.Hide();

        Form2 form2 = new Form2();

        form2.Show();
    }

    private void button2_Click(object sender, EventArgs e)
    {
        if (textBox1.Text != "")
        {
            Class1 class1 = new Class1();

            class1.setStringValue(textBox1.Text);
        }
    }
}

}

推荐答案

有几种不同的方法可以执行此操作，可以使用静态类对象，上面的示例非常适合此活动。 p>

There are a few different ways to do this, you could use a static class object, the above example would be ideal for this activity.

public static class MyStaticClass
{
  public static string MyStringMessage {get;set;}
}

您无需实例化该类，只需调用它即可。

You don't need to instance the class, just call it

MyStaticClass.MyStringMessage = "Hello World";
Console.WriteLine (MyStaticClass.MyStringMessage);

如果需要对象的实例，可以将在Form1上创建的类对象传递给Form2

If you want an instance of the object you can pass the class object that you create on Form1 into Form2 with the following.

private void button1_Click(object sender, EventArgs e)
    {
        this.Hide();
        Form2 form2 = new Form2();
        form2.MyClass = class1;
        form2.Show();
    }

然后在Form2上创建一个属性以接受类对象。

Then create a property on Form2 to accept the class object.

public Class1 MyClass {get;set;}

记住使Class1对象成为全局变量，而不是在按钮2本身中创建它。

remember to make the Class1 object a global variable rather than create it within button 2 itself.
