    Replacing "\\" to "\" in Umbraco

    Hi Guys

    I'm trying to replace a string "abc\\def" to "abc\def"
    I have tried these codes but didn't work..! I'm getting the same text returned!

    -) sampleText = sampleText.Replace(@"\\\", @"\");

    -) sampleText = Regex.Replace(sampleText ,@"\\", @"\");

    I've been stuck here for a long time..!!!
    Anybody knows the solution..?

    Hey Arun,

    The backslash is used as an escape character in Regex, so you'd need to double them to match "\"

    Depending on your requirements, you probably want to match something more like:

    sampleText.Replace(@"\\{2,}", @"\")

    Where you are matching 2 or more backslash characters and replacing them. This is a good resource for testing Regex:

    Cheers, Laura

    sampleText = sampleText.Replace(@"\\\", @"\");

    In a "verbatim" string literal prefixed by @, the \ character isn't special so there's no need to escape it. You can use sampleText = sampleText.Replace(@"\\", @"\"); as you would for replacing any other character.

    sampleText = Regex.Replace(sampleText ,@"\\", @"\");

    Here the \ isn't a special character to C#, but it's still a special character in a regex pattern, so you need sampleText = Regex.Replace(sampleText ,@"\\\\", @"\");

    I'd prefer the first option since it'll be quicker.
