如何将大量参数传递给构造函数？

Question

我有一个主窗体名为“add.cs”包含这个表单上的用户信息（它的名字，年龄等），我拖动一个按钮来添加用户的孩子信息（他们的名字，血液组，出生日期等），其单击事件打开一个表单“addchild.cs”，其中拖动了两个按钮之一来存储数据，另一个用于在运行时添加控件。在运行时添加控件我已经使用这个编码

private void button1_Click(object sender, EventArgs e) 
     { 
      try 
      { 
       childrenCount++; 

       Label lblchild = new Label(); 
       lblchild.BorderStyle = BorderStyle.Fixed3D; 
       lblchild.Location = new Point(20, (childrenCount - 1) * 50); 
       lblchild.Size = new System.Drawing.Size(50, 20); 
       lblchild.Text = "Child " + (childrenCount - 1); 
       TextBox tName = new TextBox(); //TextBox for the name 
       tName.BorderStyle = BorderStyle.Fixed3D; 
       tName.Location = new Point(120, (childrenCount - 1) * 50); 
       tName.Size = new System.Drawing.Size(135, 60); 
       tName.Text = ""; 
       DateTimePicker calendar = new DateTimePicker(); 
       //MonthCalendar calendar = new MonthCalendar(); //Calendar to choose the birth date 
       calendar.Location = new Point(310, (childrenCount - 1) * 50); 
       ComboBox bloodGroup = new ComboBox(); //ComboBox for the blood group 
       bloodGroup.Location = new Point(650, (childrenCount - 1) * 50); 
       bloodGroup.Size = new System.Drawing.Size(135, 60); 
       for (Enum.Blood_Group l = Enum.Blood_Group.O_negative; l <= Enum.Blood_Group.AB_positive; l++) 
       { 
        bloodGroup.Items.Add(l); 
       } 

       this.panel1.Controls.Add(lblchild); 
       this.panel1.Controls.Add(tName); 
       this.panel1.Controls.Add(calendar); 
       this.panel1.Controls.Add(bloodGroup); 


      } 

      catch (Exception ex) 
      { 
       MessageBox.Show(ex.Message); 
      } 

     } 

现在我已经创建了一个名为“Childrendata”用于存储的“addchild.cs”添加的控件值单独外部类。这些类包含我想要存储的所有数据。

using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Text; 
using System.Threading.Tasks; 

namespace Jain_milan 
{ 
    class Childrendata 
    { 
     string childname, childblood, childbirth; 


     public string Childbirth 
     { 
      get { return childbirth; } 
      set { childbirth = value; } 
     } 

     public string Childblood 
     { 
      get { return childblood; } 
      set { childblood = value; } 
     } 

     public string Childname 
     { 
      get { return childname; } 
      set { childname = value; } 
     } 

    } 
} 

然后在提交按钮上addchild.cs单击事件我已经使用这个代码的控制数据存储到外部类的所谓Childdata.cs的变量。

private void submitbtn_Click(object sender, EventArgs e) 
     { 
      //Checks the values 
      try 
      { 
       string message = ""; 
       foreach (Control c in this.Controls) 
       { //loop throught the elements of the form 
        if (c.GetType() == typeof(Panel)) 
        { //check if the control is a Panel 
         //Get the values from the input fields and add it to the message string 
         Panel panel1 = (Panel)c; 
         Label lblchild = (Label)(c.Controls[0]); 
         TextBox tName = (TextBox)(c.Controls[1]); 
         DateTimePicker calendar = (DateTimePicker)(c.Controls[2]); 
         ComboBox bloodGroup = (ComboBox)(c.Controls[3]); 

         //add to class 
         Childrendata childdata=new Childrendata(); 
         childdata.Childname = tName.Text; 
         childdata.Childblood= bloodGroup.Text; 
         childdata.Childbirth=calendar.Text; 


        } 
       } 
      } 

      catch (Exception ex) 
      { 
       MessageBox.Show(ex.Message); 
      } 
     } 

现在，我怎么做的构造以阵列或任何其他东西作为参数和存储的所有值，我可以调用此构造到我的主命名页面add.cs。所以上的按钮的单击事件在add.cs我可以通过使用这样的编码将这些值存储到数据库中。

Childrendata cd = new Childremdata(); 
Children child = new Children(); 

        child.Namechild = cd.Childname; 
        child.Bloodchild = cd.Childblood; 
        child.Dobchild = cd.Childbirth; 
        if (new InsertAction().Insertchildren(child)) 
        { 
         MessageBox.Show(" Children Insertion Happen "); 
        } 
        else 
        { 
         MessageBox.Show(" Children Insertion does not Happen "); 
        } 

请告诉我确切的例子，因为我已经尝试了很多来解决这个问题，但没有输出！ 请帮助请请请

我真的不知道你想要什么，但你肯定可以有构造函数Childrendata类是这样的：

public class Childrendata 
{ 
    public Childrendata(Children child) 
    { 
     childname = child.Name; 
     //etc... 

Answer 2

我建议你创建一个类，叫做一个“模型”，将包含你的孩子的数据（如姓名，血型等）。

此模型类将成为所有数据的“主”，您可以将它传递给任何需要它的窗体或类 - 所以，现在您只传递1个参数。

当您有多个孩子时，您可以将您的ChildModels放入一个集合/数组/列表/或ObservableCollection（用于数据绑定）。然后你可以遍历列表中的每个孩子来操纵它们。

如果您想要将其转换为下一步，请在您的模型上实现System.ComponentModel.INotifyPropertyChanged，并使用数据绑定使数据在窗体控件中可见，而不是通过控件将数据移入和移出控件手。

有关更多信息，请搜索模型视图控制器模式。

你可以对这个代码来看看：

Add.cs

public class Add 
    { 
     private List<Childrendata> children; //Create this List of Childrendata in Add.cs form 

     public void CreateChildControls() // This is on Button click to create another from with controls 
     { 
      children = new List<Childrendata>(); // Call Add.cs form and pass the List 
      AddChild obj = new AddChild(children); 
      obj.StoreData(); 
     } 

     public void StoreInDB() // This is on final Submit to DB 
     { 
      if (new InsertAction().Insertchildren(children)) // Pass the same List of Childrendata to Save in DB 
      { 
       MessageBox.Show(" Children Insertion Happen "); 
      } 
      else 
      { 
       MessageBox.Show(" Children Insertion does not Happen "); 
      } 
     } 
    } 

AddChild.cs

public class AddChild 
{ 
    private List<Childrendata> m_children; 
    public AddChild(List<Childrendata> children) 
    { 
     this.m_children = children; //Initialize the same List as sent by Mainform 
    } 

    public void AddControls() 
    { 

    } 

    public void StoreData() // This is on Submit button click in child form to add new child details 
    { 
     for (int i = 0; i < 10; i++) 
     { 
      // Filled with some dummy data 
      Childrendata childdata = new Childrendata(); 
      childdata.Childname = "skumar" + i; 
      childdata.Childblood = "B" + i; 
      childdata.Childbirth = "2013/10/"+ i; 

      m_children.Add(childdata); // Add to same List 
     } 
    } 
} 

Childrendata。cs

public class Childrendata 
    { 
     string childname, childblood, childbirth; 

     public string Childbirth 
     { 
      get { return childbirth; } 
      set { childbirth = value; } 
     } 

     public string Childblood 
     { 
      get { return childblood; } 
      set { childblood = value; } 
     } 

     public string Childname 
     { 
      get { return childname; } 
      set { childname = value; } 
     } 

    }
