Android Question [Solved] How to escape a string with the ( "$ ) characters within?

asales · Aug 17, 2020

I have this string: 6%>$#2"$6;2$0:6>;y48:

But If I try to make this:

B4X:

Dim s As String = "6%>$#2"$6;2$0:6>;y48:"

I get this error message in the IDE: The input string was not in the correct format.

It is because the apostrophe, but has the $ caracter after it and don't work if I make this:

B4X:

Dim s As String = $"6%>$#2"$6;2$0:6>;y48:"$

How can I fix this?

Thanks in advance for any tip.

The $ character is used in the literal string for entering a variable. So make a string with the $ character and refer to it like this:

Use of $ character in string:

    Dim str As String = "$"
    Dim s As String = $"6%>${str}#2"${str}6;2${str}0:6>;y48:"$
    Log(s)

Here is another weird way of doing it and it works:

B4X:

Dim str As String=$"6%>$#2" $6;2$0:6>;y48:"$
str=str.Replace(" ","")
Log(str)   'displays: 6%>$#2"$6;2$0:6>;y48:

[B4X] Smart String Literal

Not 100% accurate. The problem is with "$, which is the smart string terminator sequence. A $ alone will not need to be escaped.

Two more options:

B4X:

Dim s As String = $"6%>$#2"${"$"}6;2$0:6>;y48:"$ 'add the $ with a placeholder.
Dim s As String = "6%>$#2""$6;2$0:6>;y48:" 'double quotes
