我同意改变标准行为可能会混淆用户的评论。但是要消耗击键，你应该在KeyDown事件处理程序中设置SuppressKeyPress属性，例如

I agree with the comment that altering a standard behaviour may confuse users. However to consume a keystroke you should set the SuppressKeyPress property in the KeyDown event handler, e.g.

private void TextBox_KeyDown(object sender, KeyEventArgs e) {
  if (e.KeyCode == System.Windows.Forms.Keys.Back) {
    e.SuppressKeyPress = true;
    // no need to set e.Handled
    otherTextBox.Select();
  }
}

这是怎么做的，但我认为你***不要为TextBoxes设置顺序Tab键顺序使用Tab键和Shift-Tab键在它们之间导航。

Thats how it''s done, but I do think you would be better off setting a sequential tab order for the TextBoxes and navigating between them using the Tab and Shift-Tab keys.

如果有三个文本框放在这样的一个标签到另一个的方式，即标签索引是一个接一个，你可以使用 SendKeys.Send [ ^ ]将shift + tab的组合发送到标签到上一个文本框。

If three textboxes are layed out in such a way that one tabs to the other i.e. the tab indexes are one after the other, you can use SendKeys.Send[^] to send a combination of "shift + tab" to tab to previous text box.
