  TextBox textadd1 = new TextBox();
                this.Controls.Add(textadd1);

                textadd1.ForeColor = System.Drawing.Color.Black;

                textadd1.BringToFront();
                textadd1.Size = new Size(36, 24);
                textadd1.TextAlign = HorizontalAlignment.Center;
                textadd1.Text = "";
                textboxes.Push(textadd1);
                controlNames.Add(textadd1.Name);

}

  private void button4_Click(object sender, EventArgs e)
        {


                int n = 4;
                while (n < controlNames.Count)
                {
                    // First we get the textboxes
                    TextBox textBox1 = (TextBox)this.Controls.Find(controlNames[n - 3], 
                    conn.Open();
                    SqlCommand cmd = new SqlCommand("test_info", conn);
                    cmd.CommandType = CommandType.StoredProcedure;
                    cmd.Parameters.AddWithValue("@test", textBox1.Text);
                    cmd.ExecuteNonQuery();
                    conn.Close();
  
                   
                  }

                     MessageBox.Show("Data Save");
                     ClearTextBoxes();
                }
true)[0];

 private void ClearTextBoxes()
        {
            

              foreach (TextBox control in textboxes)
                   if (control is TextBox)
                    (control as TextBox).Clear();

}

What I have tried:

I Tried this code but it will delete all textboxes input event static i only want to specify the dynamic textbox to be the one only clear after being save in the db.

C#

private void ClearTextBoxes()
 {
     Action<Control.ControlCollection> func = null;

     func = (controls) =>
         {
             foreach (Control control in controls)
                 if (control is TextBox)
                     (control as TextBox).Clear();
                 else
                     func(control.Controls);
         };

     func(Controls);
 }

Add a property / field to store a reference to the "dynamic textbox" you create so you don't have to keep hunting for it in the Controls collection.

Why to use Stack<TextBox>?
Use List<TextBox> instead.

C#

List<TextBox> myTexBoxes = new List<TextBox>();

private void addTextBox_Click(object sender, EventArgs e)
{
    TextBox textadd1 = new TextBox();
    //... your code here
   myTexBoxes.Add(textadd1);
}

Then...

C#

private void ClearTextBoxes()
{
    foreach(TextBox tb in myTextBoxes)
        tb.Clear(); //tb.Text = string.Empty;
}
