如何在WinForm应用程序中检测Ctrl - Forward Slash

Question

Below is the code for Ctrl + F (from another SO post). But how do you detect a Ctrl + ForwardSlash ? or Ctrl + / (note: divide does not work)

    protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
    {
        if (1 == 1) //keyData == (Keys.Control | Keys.F))
        {
            MessageBox.Show("What the Ctrl+F?");
            return true;
        }
        return base.ProcessCmdKey(ref msg, keyData);
    }

Answer 1

Divide should work fine.

For Ctrl + \\ :

if (keyData == (Keys.Control | Keys.OemPipe) )

For Ctrl + / :

if (keyData == (Keys.Control | Keys.OemQuestion) )

For some reason (not sure why), when you trap Ctrl + these keys, they're mapping to the "shifted" keymappings.

Edit:

One trick for finding this, or any other key. Set a breakpoint on any line in that method, and look at the keyData value when you press the key you're trying to trap. I recommend doing this without hitting control. You can then use reflector to get all of the specific values for Keys , and find the "key" with the appropriate value.
