在C中读取TextBox值时出错＃

Question

我在编写程序时会遇到一些问题，它会从TextBox中读取文本。我正在阅读两个TextBoxes中的两个值，但它似乎没有任何内容正在读取。最终发生的是我将值输入到文本框中，然后按按钮将值输入到程序中。我将它设置为打印出我的文本框中的值，但是当它打印时，它看起来没有从文本框中读取任何东西。

这里是我的窗口代码：

using System; 
using System.Collections.Generic; 
using System.ComponentModel; 
using System.Data; 
using System.Drawing; 
using System.Linq; 
using System.Text; 
using System.Threading.Tasks; 
using System.Windows.Forms; 

namespace Giveaway_Program 
{ 
    public partial class giveawayProgram : Form 
    { 
     public GiveawayEntry[] entries = {}; 

     public giveawayProgram() 
     { 
      InitializeComponent(); 
     } 

     private void Giveaway_Load(object sender, EventArgs e) 
     { 

     } 

     private void panel_Paint(object sender, PaintEventArgs e) 
     { 

     } 

     private void emailText_TextChanged(object sender, EventArgs e) 
     { 

     } 

     private void nameText_TextChanged(object sender, EventArgs e) 
     { 

     } 

     private void numberOfTimes_ValueChanged(object sender, EventArgs e) 
     { 

     } 

     private void addToList_Click(object sender, EventArgs e) 
     { 
      addEntry(new GiveawayEntry(emailText.Text, nameText.Text)); 
     } 

     private void generateWinner_Click(object sender, EventArgs e) 
     { 

     } 

     private void addEntry(GiveawayEntry newEntry) 
     { 
      GiveawayEntry[] newEntries = new GiveawayEntry[entries.Length + 1]; 
      Array.Copy(entries, newEntries, entries.Length); 
      entries = newEntries; 

      for (int i = 0; i < entries.Length; i++) 
      { 
       Console.WriteLine("Name: " + entries[i].Name + ", Email: " + entries[i].Email); 
      } 
     } 
    } 
} 

下面是值进入结构：

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

namespace Giveaway_Program 
{ 
    public struct GiveawayEntry 
    { 
     string email, name; 

     public GiveawayEntry(string _email, string _name) 
     { 
      email = _email; 
      name = _name; 
     } 

     public string Email 
     { 
      get 
      { 
       return email; 
      } 
     } 

     public string Name 
     { 
      get 
      { 
       return name; 
      } 
     } 
    } 
} 

下面是从程序的控制台输出：

Answer 1

private void addEntry(GiveawayEntry newEntry) 
    { 
     GiveawayEntry[] newEntries = new GiveawayEntry[entries.Length + 1]; 
     Array.Copy(entries, newEntries, entries.Length); 
     entries = newEntries; 

     for (int i = 0; i < entries.Length; i++) 
     { 
      Console.WriteLine("Name: " + entries[i].Name + ", Email: " + entries[i].Email); 
     } 
    } 

1. 您没有添加newEntry到数组
2. 如果你只是使用List<GiveawayEntry>
3. 没有必要使它成为一个struct这会容易得多。只需使用class，除非您有令人信服的理由使其成为struct
