从表单元素中获取价值？ [英] Get value from forms element?

问题描述

您好！

我从表单上的所有文本框中获取值。

  string  name = Name.Text; 
  string  secondname = SecondName.Text; 
  string  telephone = Telephone.Text; 
  string  document = Document.Text; 
  string  dateborn = DateBorn.Text; 
  bool  bValidName = ValidName（）; 

我想从其值中创建一个对象或列表并将其传送给函数

public Add（obj）{} insted public添加（secondname，telephone，document）

怎么做？

解决方案

定义你的自定义类，例如：

 < span class =code-keyword>使用系统; 
 使用 System.Collections.Generic; 
 使用 System.Text; 
 
  class  MyFirstClass 
 {
  private   string  sfname =  string  .Empty; 
  private   string  ssname =  string  .Empty; 
  private   string  stelephone =  string  .Empty; 
  private   string  sdocument =  string  .Empty; 
 DateTime ddateborn = DateTime.MinValue; 
  private   bool  bValidName =  false ; 
 
  public   string  FirstName 
 {
  get  { return  sfname;} 
  set  {sfname =  value ; } 
} 
 
  public   string  SecondName 
 { 
  get  { return  ssname; } 
  set  {ssname =  value ; } 
} 
 
  public   string 电话
 { 
 获取 {返回 stelephone; } 
  set  {stelephone =  value ; } 
} 
 
  public   string 文件
 { 
  get  { return  sdocument; } 
  set  {sdocument =  value ; } 
} 
 
  public  DateTime DateBorn 
 {
 得到 {返回 ddateborn; } 
  set  {ddateborn =  value ; } 
} 
 
  public   bool  ValidName 
 { 
  get  { return  bValidName; } 
  set  {bValidName =  value ; } 
} 
} 

用法：

 MyFirstClass mfc =  new  MyFirstClass（）; 
 mfc.FirstName = FirstName.Text; 
 mfc.SecondName = SecondName.Text; 
 mfc.DateBorn = DateTime.Parse（DateBorn.Text）; 
 mfc.Document = Document.Text; 
 mfc.Telephone = Telephone.Text; 
 mfc.ValidName =  true ;

创建一个新类来保存对象：

  public   class  Person 
 {
  public   string 名称{ get ;  set ; } 
  public   string  SecondName { get ;  set ; } 
  public   string 电话{ get ;  set ; } 
  public   string 文档{ get ;  set ; } 
  public  DateTime DOB { get ;  set ; } 
  public   bool  IsValidName 
 {
  get  { return   false ; } 
} 
  public  Person（ string  name， string  secondName， string  telephone， string  document，DateTime dob）
 {
 Name = name; 
 SecondName = secondName; 
电话=电话; 
文件=文件; 
 DOB = dob; 
} 
  public  覆盖  string  ToString（）
 {
  return   string  .Format（< span class =code-string>  {0} {1}，Name，SecondName）; 
} 
} 

然后，您可以构造Person的实例，并将其传递给您的处理方法，或将它们存储在列表中：

列表< Person> guestList =  new  List< Person>（）; 
 ... 
 guestList.Add（ new  Person（Name.Text，SecondName.Text，Telephone.Text，Document.Text，DateTime。解析（DateBorn.Text）））; 

Hello!
I get values from all textbox on form.

string name = Name.Text;
          string secondname = SecondName.Text;
          string telephone = Telephone.Text;
          string document = Document.Text;
          string dateborn = DateBorn.Text;
          bool bValidName = ValidName();

I want create one object or list from its values and transmit this to function
public Add(obj) {} insted public Add(secondname, telephone, document)
How it make?

解决方案

Define your custom class, for example:

using System;
using System.Collections.Generic;
using System.Text;

    class MyFirstClass
    {
        private string sfname = string.Empty;
        private string ssname = string.Empty;
        private string stelephone = string.Empty;
        private string sdocument = string.Empty;
        DateTime ddateborn = DateTime.MinValue;
        private bool bValidName = false;

        public string FirstName
        {
            get { return sfname;}
            set { sfname = value; }
        }

        public string SecondName
        {
            get { return ssname; }
            set { ssname = value; }
        }

        public string Telephone
        {
            get { return stelephone ; }
            set { stelephone  = value; }
        }

        public string Document
        {
            get { return sdocument; }
            set { sdocument  = value; }
        }

        public DateTime DateBorn
        {
            get { return ddateborn ; }
            set { ddateborn  = value; }
        }

        public bool ValidName
        {
            get { return bValidName ; }
            set { bValidName = value; }
        }
}

Usage:

MyFirstClass mfc = new MyFirstClass();
mfc.FirstName = FirstName.Text;
mfc.SecondName = SecondName.Text;
mfc.DateBorn = DateTime.Parse(DateBorn.Text);
mfc.Document = Document.Text;
mfc.Telephone = Telephone.Text;
mfc.ValidName = true;

More about classes you''ll find here: class (C# Reference)[^]
Classes (C# Programming Guide)[^]

Create a new class to hold the objects:

public class Person
    {
    public string Name { get; set; }
    public string SecondName { get; set; }
    public string Telephone { get; set; }
    public string Document { get; set; }
    public DateTime DOB { get; set; }
    public bool IsValidName
        {
        get { return false; }
        }
    public Person(string name, string secondName, string telephone, string document, DateTime dob)
        {
        Name = name;
        SecondName = secondName;
        Telephone = telephone;
        Document = document;
        DOB = dob;
        }
    public override string ToString()
        {
        return string.Format("{0} {1}", Name, SecondName);
        }
    }

You can then construct an instance of a Person, and pass it through to your processing methods, or store them in a list:

List<Person> guestList = new List<Person>();
...
guestList.Add(new Person(Name.Text, SecondName.Text, Telephone.Text, Document.Text, DateTime.Parse(DateBorn.Text)));
