How do I put a double quote into a string RRS feed

  • Question

  • I have a problem that seems trivial. In an argument to an activity I need to supply a path.

    This is done by this code:
    String.Format("a -bd -y -tzip {0} {1}\* -r", Path.Combine(BinariesDirectory, "output.zip"), BinariesDirectory)

    However, the directories parameters contain spaces so they have to have quotes around them. I tried with single quote ' that works fine to put in the string, but the command shell executing the command ignores these. So it has to be double quote "

    I have tried all methods I have fount on the Internet, for example to have a backslash before the double quote and to have three double quotes, but nothing seems to work. I get a compiler error as below.

    Error 4 Compiler error(s) encountered processing expression "String.Format("a -bd -y -tzip \"{0}\" '{1}\*' -r", Path.Combine(BinariesDirectory, "output.zip"), BinariesDirectory)".
    Comma, ')', or a valid expression continuation expected.

     

    Please Help!

    Thanks!

  • did you try it like this:

     

    String.Format("a -bd -y -tzip ""{0}"" ""{1}"" \* -r", Path.Combine(BinariesDirectory, "output.zip"), BinariesDirectory)

  • Hi Tomas,

    Puting : """"  will result a simple quote : "

    I think it is what you are looking for :)

  • VB or C#?

    vb doesn't use \ to escape but C# does. for VB, Michael's advice is spot on. 4 double quotes.

  • That almost works...

    Four " removes the compilation error, but the result is two "" and that is not handled by the command shell. It needs just one ".

    This is really strange... It might have something to do with localization as well?

  • If I am right it is always VB syntax in WorkFlow Foundation Parameters.

    Se above for my following problem, four double quotes brings away the compilation error, but does not solve the real problem.

  •         Dim QpathS As String = String.Format("a -bd -y -tzip {0} {1} -r", _
                                                 quotedSTR(IO.Path.Combine(BinariesDirectory, "output.zip")), _
                                                 quotedSTR(IO.Path.Combine(BinariesDirectory, "*")))

     


        Function quotedSTR(stringNeedingQuotes As String) As String
            Dim sb As New System.Text.StringBuilder(stringNeedingQuotes)
            sb.Append(ControlChars.Quote)
            sb.Insert(0, ControlChars.Quote)
            Return sb.ToString
        End Function
