Multiple .replace() in asp.net/vb.net

P: n/a
Greetings

I am using VB in my ASP.NET project that uses an admin web site to
populate a database that provides content for a front end web site. I am
looking for a way to use replace() to replace multiple entries of an
object within a string. That is, if a user hit [enter] twice to create
one new line, but [enter] just once to create another, I want both types
([vbcrlf vbcrlf] & [vbcrlf}) replaced by </p><p>.

The reason is this: I don't want to strip out multiple vbcrlf's at the
admin site/database, because the users are used to hitting [enter] twice
to create a new line (by creating a blank line between paragraphs).
However, when the content is displayed on the front end site, I need to
replace *any number* of sequential vbcrlf's (from just a single one, to
multiple ones of any number) with a single </p>vbcrlf[tab character]<p>
(the data will be dumped inside a single paragraph: <p>[data]</p>, so
this replacement of vbcrlf will break up the data into multiple paragraphs).

I am also curious as to how to string multiple replace()'s together.
That is, I want to convert regular quotes to curly quotes. I want to
replace one kind of single quote "text -> “text and then within the same
string also replace another kind of single quote text" -> text”. I am
sure that the replace() was built to have multiple expressions within
the bracket, but I can't seem to find any info on that.

And finally, any info on how to explicitly set certain special
characters, like tabs and spaces (much like how vbcrlf creates a return)
would be appreciated.

TIA

You should look into learning about the RegEx class. It's daunting at
first, but it will allow you to create replacements that you need easily.

replace all double VBCRLFs with single ones repeatedly until there are no
double VBCRLFs left, then do your replace.

Dim x As String

Do While x.IndexOf(System.Environment.NewLine & System.Environment.NewLine)
= 0


x = Replace(x, System.Environment.NewLine & System.Environment.NewLine,
System.Environment.NewLine)

Loop

x = Replace(x, System.Environment.NewLine, "</p><p>")

You can't write multiple replacements with a single bracket-pair,
but you can use something like
myString = myString.Replace(..).Replace(...).Replace(...)

Maybe you can replace "<space><quote>" with "<space><open curly quote>"
and so on.

Use Regex to replace. You can set up Regex with a pattern that replaces one,
or more, instances of \r\n with </p><p>. It would be far more costly to have
it loop until all \r\n were replaced.
