如何使用c＃中的regex.replace用反斜杠替换单个字符？

Question

If I do this:

Regex.Replace("unlocktheinbox.com", "[t]", "\\$&");

My result is:

"unlock\\theinbox.com"

I'm expecting it to be

"unlock\theinbox.com"

I'm trying to replace "t" with "\\t" using regex.replace. I made this example very basic to explain what I'm trying to accomplish.

Answer 1

Try following

var result = Regex.Replace("unlocktheinbox.com", "[t]", @"\");

Note that, if you observe result while debugging via hovering mouse on result . it will look like unlock\\\\theinbox.com because \\ is escaped. But actually, if you print result or use anywhere it will be unlock\\theinbox.com
