How to use multiple modifier keys in C#

Question

I am using a keydown event to detect keys pressed and have several key combinations for various operations.

if (e.KeyCode == Keys.C && e.Modifiers == Keys.Control && e.Modifiers == Keys.Shift) {     //Do work } else if (e.KeyCode == Keys.V && e.Modifiers == Keys.Control) {     //Paste } 

For some reason the key combination in which I hit Ctrl + Shift + C is not working. I have re ordered them, and placed it at the top thinking it might be interference from the Ctrl + C, and even removed the Ctrl + C to see if it was causing a problem. It still does not work. I know it's probably something very simple, but can't quite grasp what it is. All of my 1 modifier + 1 key combination's work fine, as soon as I add a second modifier is when it no longer works.

Answer 1

if (e.KeyCode == Keys.C && e.Modifiers == (Keys.Control | Keys.Shift)) {     //Do work } else if (e.KeyCode == Keys.V && e.Modifiers == Keys.Control) {     //Paste } 

Answer 2

Have you tried e.Modifiers == (Keys.Control | Keys.Shift)?
