我如何在WPF中动态地捕获编号的文本框的文本？

我正在创建一个联系人添加，我想添加选项以添加超过1个电话号码。我允许创建更多文本框，以便用户使用此按钮添加数字：

        private void AddPhoneNumberButton_Click(object sender, RoutedEventArgs e)
        {
            int numberOfTextBoxes = PhoneNumberStackPanel.Children.OfType<TextBox>().Count();

            TextBox txtbox = new TextBox();
            txtbox.Name = $"PhoneNumberTextBox{numberOfTextBoxes}";
            txtbox.Width = 200;
            txtbox.Background = Brushes.White;
            txtbox.Margin = new Thickness(0,10,0,0);
            PhoneNumberStackPanel.Children.Add(txtbox);
        }

现在如何动态地参考这些文本框。就像我想使用此循环中在这些文本框中捕获所有文本：

for ( int i = 0 ; i < PhoneNumberStackPanel.Children.OfType<TextBox>().Count() ; i++){}

原文

I am creating a contacts add and I want to add the option to add more than 1 phone numbers.
I allow the creation of more textboxes for the user to add number with this button:

        private void AddPhoneNumberButton_Click(object sender, RoutedEventArgs e)
        {
            int numberOfTextBoxes = PhoneNumberStackPanel.Children.OfType<TextBox>().Count();

            TextBox txtbox = new TextBox();
            txtbox.Name = quot;PhoneNumberTextBox{numberOfTextBoxes}";
            txtbox.Width = 200;
            txtbox.Background = Brushes.White;
            txtbox.Margin = new Thickness(0,10,0,0);
            PhoneNumberStackPanel.Children.Add(txtbox);
        }

Now how to I refer to those textboxes dynamically. Like if I want to grab all the text in these textboxes with this loop:

for ( int i = 0 ; i < PhoneNumberStackPanel.Children.OfType<TextBox>().Count() ; i++){}

使用foreach循环：

foreach(TextBox tb in PhoneNumberStackPanel.Children.OfType<TextBox>())
{
    string text = tb.Text;
}

还考虑用itemscontrol替换stackpanel ：

private void AddPhoneNumberButton_Click(object sender, RoutedEventArgs e)
{
    int numberOfTextBoxes = PhoneNumberItemsControl.Items.Count;

    TextBox txtbox = new TextBox();
    txtbox.Name = $"PhoneNumberTextBox{numberOfTextBoxes}";
    txtbox.Width = 200;
    txtbox.Background = Brushes.White;
    txtbox.Margin = new Thickness(0,10,0,0);
    PhoneNumberItemsControl.Items.Add(txtbox);
}

foreach(TextBox tb in PhoneNumberItemsControl.Items.OfType<TextBox>())
{
}

您可以进行的下一步是将文本框移动到itemscontrol.itemtemplate。（一旦您需要比单个元素更复杂的视觉结构，它就会成为“必须做的”）

use foreach loop:

foreach(TextBox tb in PhoneNumberStackPanel.Children.OfType<TextBox>())
{
    string text = tb.Text;
}

also consider replacing StackPanel with ItemsControl:

private void AddPhoneNumberButton_Click(object sender, RoutedEventArgs e)
{
    int numberOfTextBoxes = PhoneNumberItemsControl.Items.Count;

    TextBox txtbox = new TextBox();
    txtbox.Name = quot;PhoneNumberTextBox{numberOfTextBoxes}";
    txtbox.Width = 200;
    txtbox.Background = Brushes.White;
    txtbox.Margin = new Thickness(0,10,0,0);
    PhoneNumberItemsControl.Items.Add(txtbox);
}

foreach(TextBox tb in PhoneNumberItemsControl.Items.OfType<TextBox>())
{
}

next step which you can make is moving TextBoxes into ItemsControl.ItemTemplate. (it becomes a "must-do" as soon as you need visual structure more complex than a single element)
