将文本框中的用户输入从一种表单传输到另一种表单

Question

我正在制作一个程序，用户可以在一个表单上的文本框中输入值，然后数据将转入其他表单。我认为这样做的最好方法是将用户数据存储在多个数组中，然后将这些数组放在一边，但此时我真的很麻烦。该文本框也被创建，一旦用户输入他们需要多少这样的文本框不存在于页面上最初

string q = combobox1.SelectedItem.ToString(); 
     int g = Convert.ToInt32(q); 
     MessageBox.Show("I have added " +(g-1) +" Films to the list"); 
     TextBox[] FilmTitle1 = new TextBox[int.Parse(q)]; 
     TextBox[] FilmBudget1 = new TextBox[int.Parse(q)]; 
     TextBox[] FilmBoxOffice1 = new TextBox[int.Parse(q)]; 
     TextBox[] FilmDirector1 = new TextBox[int.Parse(q)]; 
     TextBox[] FilmRtScore1 = new TextBox[int.Parse(q)]; 
     TextBox[] FilmGenre1 = new TextBox[int.Parse(q)]; 
     int y = 500; 
     for (int i = 0; i < g; i++) 
     { 
      FilmTitle1[i] = new TextBox(); 
      FilmTitle1[i].Text = "Film Title"; 
      FilmTitle1[i].Size = new Size(162, 20); 
      FilmTitle1[i].Location = new Point(106, y); 
      FilmTitle1[i].Tag = 0; 
      this.Controls.Add(FilmTitle1[i]); 
      y= y + 40; 

private void Createbar_Click(object sender, EventArgs e) 
    { 
     BarGraphCreation frm = new BarGraphCreation(FilmTitle.Text, FilmBudget.Text, FilmBoxOffice.Text, FilmDirector.Text, FilmGenre.Text, ft1, FilmBudget1.Text, FilmBoxOffice1.Text, FilmDirector1.Text, FilmGenre1.Text); 
     frm.Show(); 
    } 

但是，当我做这种方式它说，没有构建文本框，尽管事实上，它允许它在程序的其他地方。 任何类型的帮助是极为赏识

public class Form 
{ 
     // your code ... 

     string q = combobox1.SelectedItem.ToString(); 
     int g = Convert.ToInt32(q); 
     MessageBox.Show("I have added " +(g-1) +" Films to the list"); 
     public TextBox[] FilmTitle1 = new TextBox[int.Parse(q)]; 
     public TextBox[] FilmBudget1 = new TextBox[int.Parse(q)]; 
     public TextBox[] FilmBoxOffice1 = new TextBox[int.Parse(q)]; 
     public TextBox[] FilmDirector1 = new TextBox[int.Parse(q)]; 
     public TextBox[] FilmRtScore1 = new TextBox[int.Parse(q)]; 
     public TextBox[] FilmGenre1 = new TextBox[int.Parse(q)]; 
     int y = 500; 
     for (int i = 0; i < g; i++) 
     { 
      FilmTitle1[i] = new TextBox(); 
      FilmTitle1[i].Text = "Film Title"; 
      FilmTitle1[i].Size = new Size(162, 20); 
      FilmTitle1[i].Location = new Point(106, y); 
      FilmTitle1[i].Tag = 0; 
      this.Controls.Add(FilmTitle1[i]); 
      y= y + 40; 

    private void Createbar_Click(object sender, EventArgs e) 
    { 
     BarGraphCreation frm = new BarGraphCreation(this); 
     frm.Show(); 
    } 
} 

public class BarGraphCreation 
{ 
    // your code... 

    Form form; 
    public BarGraphCreation(Form form) 
    { 
     // ... 
     this.form = form; 
    } 

    private void function() 
    { 
     // here you can work with your data like 
     // form.FilmTitle1 and so on 
    } 
}

你应该避免将像TextBox整个对象到一些其他控件。总体思路是你永远只会传递数据（信息）。

由于Form布局是动态创建的，所以关于它的信息应该保存在某个地方，在这里可以轻松地再次访问。

实施例（包括阵列和列表作为例子）：

public class Form1 : Form 
{ 
    private TextBox[] FilmTitles; 
    private List<TextBox> FilmBudget = new List<Textbox>(); 

    //code removed for brevity 

    private void Button1_Click(/***/) 
    { 
     FilmBudget.Clear(); 

     int count = Convert.ToInt32(q); 
     FilmTitles = new TextBox[count]; 

     for (int i = 0; i < count; i++) 
     { 
      FilmTitles[i] = new TextBox() 
      { 
       Text = "Programmer in one day", 
       Size = new Size(162, 20) 
       // all other definitions 
      }; 


      FilmBudget.Add(new TextBox() 
      { 
       Text = "1225", 
       Size = new Size(162, 20) 
       // all other definitions 
      }; 

      this.Controls.Add(FilmTitles[i]); 
      this.Controls.Add(FilmBudget[i]); 

      //Now you are holding all the TB & text in global variables (arrays/lists) 
     } 
    }  

    private void Createbar_Click(object sender, EventArgs e) 
    { 

     BarGraphCreation frm = new BarGraphCreation(
       FilmTitles.Select(a => a.Text).ToArray(), 
       FilmBudget.Select(a => a.Text).ToArray()); 
     frm.Show(); 
    }  

} 

其中：

public class BarGraphCreation : Form 
{ 
    public BarGraphCreation(string[] Titles, string[] Budgets) 
    { } 
} 

注意，该部分是使用LINQ选择确切属性（值）分为2个数组：

BarGraphCreation frm = new BarGraphCreation(
       FilmTitles.Select(a => a.Text).ToArray(), 
       FilmBudget.Select(a => a.Text).ToArray());
