How to assign a shortcut key (something like Ctrl+F) to a text box in Windows Forms?

问题:

I am building a tool using C#. It's a Windows application. I have one text box on a form, and I want to assign focus to that text box when the user presses Ctrl + F or Ctrl + S.

How do I do this?

回答1:

Capture the KeyDown event and place an if statement in it to check what keys were pressed.

private void form_KeyDown(object sender, KeyEventArgs e) {     if ((e.Control && e.KeyCode == Keys.F) || (e.Control && e.KeyCode == Keys.S)) {         txtSearch.Focus();     } } 

回答2:

One way is to override the ProcessCMDKey event.

protected override bool ProcessCmdKey(ref Message msg, Keys keyData) {     if (keyData == (Keys.Control | Keys.S))     {         MessageBox.Show("Do Something");         return true;     }     return base.ProcessCmdKey(ref msg, keyData); } 

EDIT: Alternatively you can use the keydown event - see How to capture shortcut keys in Visual Studio .NET.

回答3:

Add an event that catches a key press on the form, analyse the key press and see if it matches one of your shortcut keys and then assign focus.
