带有字典参数的方法

Question

请告诉我或指出解决这个问题的正确方法，我还没有经验，很难理解如何解决这个问题。如果有任何帮助，我将不胜感激。

我的 Form 类应该只包含一个公共方法：

class Form
{
    public void FillForm(Dictionary<string, string> values)
    {
        ...
    }
    ...
}

它将用仅基于存储在字典中的字段名-值对的值填充此表单（实际上是任何类似实现的表单）。

And I have such a xpath to fill out a form using a dictionary, it must be one for the whole task

表单有多个字段

1. 带有问题的文本
2. 姓名
3. 电子邮件
4. 联系电话
5. 位置
6. 年龄

Answer 1

字典包含键值对。密钥必须是唯一的。所以在这种情况下，字典不是一个好方法。

你必须先构建一个领域模型：

//This will hold your user information
public class UserInfo
{
    public string Name { get; set; }
    public string Email { get; set; }
    public string Location { get; set; }
    public int Age { get; set; }
    public string Phone { get; set; }
}

//this other class is called a viewmodel which combains your user and the question posed by the user
public class FormData
{
    public UserInfo user { get; set; }
    public string question { get; set; }
}

//this class is your public facing interface which will interact with the user/front-end form

public class Questionaire
{
    FormData _data; 
    public void FillForm(FormData data)
    {
        //do whatever you want with the data
        //save to database, send by email, whatever
        _data = data;
        }
    }


    class Program
    {
        static void Main(string[] args)
        {

//this is how you use it to collect data from the user
            Questionaire questionaire = new Questionaire();
            questionaire.FillForm(new FormData
            {
                question = "your question goes here",
                user = new UserInfo
                {
                    Name = "YourName",
                    Age = 20,
                    Email = "someemail",
                    Location = "yourlocation",
                    Phone = "0123665555"
                }
            });
        }
    }

选项 2（因为您坚持使用字典）：

    public class UserInfo
    {
        public string Name { get; set; }
        public string Email { get; set; }
        public string Location { get; set; }
        public int Age { get; set; }
        public string Phone { get; set; }
    }


        Dictionary<string, UserInfo> _values;
        public void FillForm(Dictionary<string, UserInfo> values)
        {
            _values = values;
        }


//You call it like this:
            Dictionary<string, UserInfo> dic = new Dictionary<string, UserInfo>();
            dic.Add("question1", new UserInfo { Age = 20, Name = "Name1" });
            dic.Add("question2", new UserInfo { Age = 20, Name = "Name2" });

            Form form = new Form();
            form.FillForm(dic);

选项 3，但这不是可行的方法：

public class Form2
{
    Dictionary<string, string> _values;
    public void FillForm(Dictionary<string, string> values)
    {
        _values = values;
    }
}


Dictionary<string, string> user1 = new Dictionary<string, string>();
user1.Add("question1", "Users question goes here");
user1.Add("Name", "name1");
user1.Add("Age", "age");
            //...
var form2 = new Form2();
form2.FillForm(user1);
