按表单C＃增加每个按钮点击表单的数量 [英] Increment number per button click form by form C#

问题描述

这适用于排队系统。当单击下一个按钮（form1）时，必须处理增量编号文本框格式为2.



我尝试过：



//只能以同样的形式试用

this is for a queuing system. When the next button is clicked (form1) the increment number must be processed textbox which is in form 2.

What I have tried:

//only tried in same form

namespace Queuing_System
{
    public partial class Counter1 : Form
    {
        int count = 0;
        public Counter1()
        {
            InitializeComponent();
        }

        private void btnNext1_Click(object sender, EventArgs e)
        {
            count++;
            textBox.Text = count.ToString();
            
            
        }

        
    }
}

推荐答案

google在表格之间传递值c＃windows application ，你会发现很多方法可以达到这个目的，

前两个结果从上面

在表格之间传递数据 [ ^ ]

传递数据c＃窗体 [ ^ ]



示例:(这是其中一种方法）

google "passing values between forms c# windows application" , you will find lot of ways to achieve this,
first two results from the above
Passing Data Between Forms[^]
Passing data c# windows form[^]

example: ( this is one of the method)

public partial class Form1 : Form
   {
       public Form1()
       {
           InitializeComponent();
       }
       int count = 0;
       Form2 objForm2 = new Form2();

       private void btnNext1_Click_1(object sender, EventArgs e)
       {
           count++;
           objForm2.textBox1.Text = count.ToString();
       }

       private void Form1_Load(object sender, EventArgs e)
       {
           objForm2.Show(); // show the form in form load or any other event, before incrementing the counter
       }
   }

Form2 将文本框的Access修饰符从 Private 更改为 Public

选择Form2 - >设计视图 - >点击文字框 - >右键单击 - >属性 - >找到Modifier属性 - >从私人变为公共。

In Form2 change the Access modifier of the textbox from Private to Public
Select Form2 -> Design View -> Click the Textbox -> right click -> properties -> find the Modifier property -> Change from Private to Public.
