C# 如何在C中将文本框居中放置在边框内#

在我的

WP7

应用程序中，我正在

边框内创建一个
Textbox
。如何将
文本框
精确对齐在
边框的中心

         Border rectangleborder = new Border();
         rectangleborder.Background = new SolidColorBrush(Colors.Transparent);
         rectangleborder.BorderBrush = new SolidColorBrush(Colors.Black);
         rectangleborder.BorderThickness = new Thickness(2);
         rectangleborder.Width = width;
         rectangleborder.Height = width;
         TextBox textbox = new TextBox();
         textbox.Text = "1";
         textbox.Background = new SolidColorBrush(Colors.Transparent);
         textbox.Foreground = new SolidColorBrush(Colors.Yellow);
         textbox.BorderBrush = new SolidColorBrush(Colors.Transparent);
         this.canvas1.Children.Add(rectangleborder);
         rectangleborder.SetValue(Canvas.LeftProperty, 30 + (j - 1) * width);
         rectangleborder.SetValue(Canvas.TopProperty, 30 + (i - 1) * width);
         rectangleborder.Child = textbox;

您需要将
水平对齐
设置为水平对齐，将
垂直对齐
设置为垂直对齐：

TextBox textbox = new TextBox();
textbox.HorizontalAlignment = HorizontalAlignment.Center;
textbox.VerticalAlignment = VerticalAlignment.Center;

结果应该是这样的：

  TextBox textbox = new TextBox();
  textbox.HorizontalAlignment = HorizontalAlignment.Center;
  textbox.VerticalAlignment = VerticalAlignment.Center;


您还可以使用以下方法对内部文本进行allign：-

     textBox.TextAlign = HorizontalAlignment.Center;
