Some string variables have a " in the data which recks with my php code. I want to take it out in my C# code before the data gets passed to php. I just can't remember the way of doing it, but I tried with this :
line.Replace(#""", "");
This is not correct in Xamarin, what is the good syntax?

I guess this would work.
line.replace("\"","");

use \ to escape it.
line.Replace("\"", "");

How to decode ' in c# [duplicate]

I found a similar question on how to decode ^#39; or simply ' in php, but I have been having trouble finding a way of decoding that value in c#. Thoughts? I have been trying the following in my code...
agenda.MeetingLocation = agenda.MeetingLocation.Replace("'", "''")
However, the value in my form field is John Doe's test. The value I see for agenda.MeetingLocation is:
John Doe's test
(the ^ is a &)

This should work if it's encoded like "& #39;" instead of "^#39;". Are you sure your input uses "^"?
System.Web.HttpUtility.HtmlDecode("John Doe's test.");

I was wondering if there is an easy way convert a string to RTF in C#.
Not only the standard characters but special characters i.e. as €ƒ…†‡ to.

Use the RichTextBox control. You can set it's Text property to a string then get back it's Rtf property.
