WinForms Dynamic TextBox Creation Guide

Creating text box controls dynamically in WinForms can be achieved through the following steps:

1. Create a button on the form to trigger the operation of dynamically creating text box controls.
2. Add code in the Click event handler of the button to dynamically create a text box control.
3. Instantiate a new text box control using the TextBox class, and set its properties.
4. Add the newly created text box control to the Controls collection of the form to display it on the form.

Below is an example code for dynamically creating text box control in WinForm.

private void btnCreateTextbox_Click(object sender, EventArgs e)
{
    // 创建一个新的文本框控件
    TextBox newTextBox = new TextBox();

    // 设置文本框控件的属性
    newTextBox.Location = new Point(50, 50); // 设置文本框在窗体上的位置
    newTextBox.Size = new Size(100, 20); // 设置文本框的大小

    // 将新创建的文本框控件添加到窗体的Controls集合中
    this.Controls.Add(newTextBox);
}

By using the above code, a text box control will be dynamically created and displayed at the specified position on the form when the button is clicked. You can modify the properties of the text box based on your actual needs and manipulate it in other event handlers.
