您能在下面为我解释一下这段代码吗 [英] Can you exlain for me this code below

问题描述

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Drawing;

namespace ProgrammerGuide_001
{
    public class WinForm:Form
    {
        private Button button1;
        private TextBox textBox1;
        public WinForm()
        {
        }
        static void Main(string[] args)
        {
            WinForm myFrm = new WinForm();
            myFrm.button1 = new Button();
            myFrm.textBox1 = new TextBox();
            myFrm.Text = "my first window application";
            Application.Run(myFrm);
        }
    }
}

我有一个问题，当我这样声明2个对象变量时:

I have a question that when I declare 2 object variable like this:

private Button button1;
private TextBox textBox1;

为什么我无法使用以下语句实例化:

why I can''t instantiate with the following statements:

button1=new Button();
textBox1=new TextBox();

但是这段代码可以:

but this code can:

myFrm.button1 = new Button();
myFrm.textBox1 = new TextBox();

推荐答案

因为要在表单类的实例中实例化它们.这段代码大部分都是有延迟的，没有任何意义，一个基本的控制台应用程序是学习此概念的一种更好的方法，而不是那么分心.您处于静态方法中，它没有状态，因此对象不存在于main内部，而是仅存在于该类的INSTANCE内部.

Because you''re instantiating them inside the instance of the form class. This code is mostly retarded, it makes no sense, a basic console app is a better way to learn this concept, not as many distractions. You''re in a static method, it has no state, so the objects don''t exist inside main, they only exist inside an INSTANCE of the class.
