How to remove special characters from string in C#

Question

I want to remove some special characters from a string. This is my string :

"\":\"mysitetext.co.au/tt/L6EL92JZ\"}"

I want to get results like this:

"mysitetext.co.au/tt/L6EL92JZ"

I tried with regex command as below but didn't work

myLink = "\":\"mysitetext.co.au/tt/L6EL92JZ\"}";
Regex reg = new Regex("\":}");
myLink = reg.Replace(myLink , "");

What am I doing wrong here?

Thank you.
