C# How to programmatically tab between controls
提问by NXT
I would like to be able to programmatically emulate the keyboard navigation for dialog boxes.
我希望能够以编程方式模拟对话框的键盘导航。
I have a custom hardware device with a keypad that I would like to use for dialog box navigation.
我有一个带有键盘的自定义硬件设备，我想将其用于对话框导航。
I know about Focus(), but I'd rather do something that automatically respected the tab order. By emulating the keyboard navigation I don't have to worry about re-inventing complex behavior for each type of control.
我知道 Focus()，但我宁愿做一些自动遵守 Tab 键顺序的事情。通过模拟键盘导航，我不必担心为每种类型的控件重新发明复杂的行为。
Does anyone know how to do this?
有谁知道如何做到这一点？
Thanks!
谢谢！

You could use P/Invoke to call the Windows API function keybd_eventto simulate pressing the Tab key.
您可以使用 P/Invoke 调用 Windows API 函数keybd_event来模拟按 Tab 键。
Bonus: you can use your device to enter tabs into a text editor as well! ;)
奖励：您也可以使用您的设备在文本编辑器中输入标签！;)

在 Winforms 中：
Control nextControl = this.GetNextControl(myControl, true);
To simulate a tab press, I believe it's the following:
要模拟 Tab 按下，我相信它如下：
SendKeys.Send("{TAB}");
