We have noticed that a CR LF transmitted in a string to from a web service
will be replaced with the (unix style) single LF. This translation is not
undone on the client side. (Both client and server are .Net)

Before we go and manually undo the translation on the client side is there
some setting on the web reference or the WSDL file that would take care of
this? Adding a replace() on the client side call seems like a bit of a
hack.

Any ideas?

Are you not using the "\r\n" style for CRLFs embedded in strings?
This works for me:

[WebMethod]
public string MyMethod()
{
return "This is the first line.\r\nAnd this is the second one."
}

This will always preserve the line feed.

Hrmm... What version of .Net are you using? We have tried this several
different ways and have had no luck.

When the client side deserializes the data, the \r\n is replaced with just a
\n (unless the data is in a dataset)

Yes, you're right :( the \r gets eaten by .NET
I did not notice it because if you happen to display the string in a
MessageBox, for example, you don't notice the difference.

But, there are some solutions to that.

1) If you really, really need that \r\n pair try to use the @-quoting. Like
this:

[WebMethod]
public string MyMethod()
{
return @"This is the first line.\r\nAnd this is the second one.";
}
The only problem here is that you now get the "\r\n" ad literam (as
literals of the string). So far I don't know how can you revert it back...

2) You can write the webmethod to return an ArrayList in the web service;
suppose we read the strings from an xml document:

[WebMethod]
public ArrayList GetStrings()
{

ArrayList list = new ArrayList();
list.Add("This is line 1.");
list.Add("This is line 2.");
return list;

}

and, on the client side:
[...]
WebRefFileService.FileService wfs = new WebRefFileService.FileService();
ArrayList al = new ArrayList(wfs.GetStrings());
etc.

And that's where my knowledge stops :)
Regards,
Dan
