I have a path that is named defaultPath I want to add it into this verbatim string literal but can quite get the quotes around it.
@\"\"\"C:\\Mavro\\Mav
Use string.Format to insert the variable between the quotes:
string path = "Data.Apple";
string verbatim = string.Format(@"""C:\Mavro\MavBridge\Server\MavBridgeService.exe"" /service /data ""{0}""", path);
MessageBox.Show(verbatim);
It makes it easier to read and to implement, you can replace other portions of the path with variable sections in a similar manner.
If you try to just append the "defaultPath" variable to the end, it will never work correctly, as you've already added the closing "
