Replace double backslash \\ with single backslash \ in a string

  • 9 years ago

    hi all,

    How can i replace a double backslash with a single backslash. I am using the following code:

    string pathofbook = server.mappath("~");

    string s = pathofbook.replace("\\","\");

    But the above code gives me an error.....unrecognised escape parameter(i.e. for single backslash). I tried using : pathofbook.replace("\\", @"\") but it doesn't do anything. It returns the same string.

    How can i perform this replacement?

    Khan: the solution you have provided doesn't change the output. I mean, it returns the same string as input string.

    Sraja: as per your solution is concerned, you have used forward slash instead of black slash. The forward slash( / ) doesn't trouble you much. The problem occurs when you use back slash( \ ). It gives you an error like "Newline in Constant".
