Backslash Escape Sequence displaying both backslashes

问题

I currently have a string like this:

string login = "DOMAIN\" + userID

Obviously this does not work as I need the backslash escape sequence, right?

string login = "DOMAIN\\" + userID

This displays DOMAIN\\jcwhisman with 2 backslashes?

I have tried all of these in hopes that something will work. While these don't all display 3 slashes, none of them display what I need:

• string login = @"DOMAIN\" + userID

• string login = @"DOMAIN\\" + userID

• string login = "DOMAIN\\" + userID

• string login = "DOMAIN\" + userID

I know some of those don't seem logical, but I have just been trying everything I can.

I need it to display as DOMAIN\jcwhisman

回答1:

Your two ways are correct and should give you exactly what you want:

1. string login = @"DOMAIN\" + userID

2. string login = "DOMAIN\\" + userID

Just make sure that you don't have a backslash at the beginning of your userID.
