如何使用列表或字典中的数据填充7个文本框？ [英] How do I populate 7 textboxes with data from a list or dictionary ?

问题描述

我正在开发一个项目，当我加载表单时，有7个文本框，其中有相应的标签。当表单加载时，我需要使用列表或字典中的第一个数据字符串填充到文本框中。然后我有4个按钮，以循环列表/词典中的其他数据串。



我尝试过：



我对编程很新，还没有真正尝试过。我一直在搜索示例或教程，但还没找到我到底的确切内容。

I am working on a project where when I load a form there is 7 text boxs with there corresponding labels. When the form loads I need to populate with the 1st string of data from a list or dictionary into the text boxes. Then I have 4 buttons in order to cycle through the other strings of data in the list/dictionary.

What I have tried:

I am very new to programming and have not really tried much yet. I have been searching for examples or tutorials but have not found exactly what I am after yet.

您好会员13029812 ，



这个问题的简单解决方案是：



1）遍历所有控件形式。

2）看看它是否是一个文本框。如果是，则将文本更改为第一个列表项。

Hi Member 13029812,

The simple solution to the problem is:

1) Loop through all the controls of the form.
2) See if it is a textbox. If it is, then change the text to the first list item..

List<string> MyList = new List<string>();
MyList.Add("text 1");
MyList.Add("text 2");

foreach (Control Ctl in Controls)
    if (Ctl is TextBox)
        (Ctl as TextBox).Text = MyList[0];

请谷歌关于IS和AS如何运作。

我不会这样做，但这会指出你正确的方向：

I wasn't going to but this will point you in the right direction:

using System;
using System.Collections.Generic;
using System.Windows.Forms;

namespace WFDataList
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            employees = GetEmployeesList();
            SetButtonState();
            SetFields();
        }

        private int index = 0;
        private List<Employee> employees { get; set; }

        private List<Employee> GetEmployeesList()
        {
            return new List<Employee>
            {
                new Employee("Duane", "Wales", "Taber", "[e-mail]", "869-9681", "

55,000， 管理），
new 员工（ Lori， Wales， Taber， [e-mail]， 869-9682，

55,000", "Administration"), new Employee("Lori", "Wales", "Taber", "[e-mail]", "869-9682", "
