The HTML string to decode.

Return Value

The decoded text.

URL encoding ensures that all browsers will correctly transmit text in URL strings. Characters such as a question mark (?), ampersand (&), slash mark (/), and spaces might be truncated or corrupted by some browsers. As a result, these characters must be encoded in <a> tags or in query strings where the strings can be re-sent by a browser in a request string.

HtmlDecode decodes text that has been transmitted to the server.

HtmlDecode is a convenient way to access the System.Web.HttpUtility.HtmlDecode method at run time from an ASP.NET application. Internally, HtmlDecode uses System.Web.HttpUtility.HtmlDecode to decode strings.

The following example contains the function LoadDecodedFile, which decodes the data from a file and copies it into one string.

<%@ PAGE LANGUAGE = "C#" %>
 <%@ IMPORT NAMESPACE = "System.IO" %>
 <html xmlns="">
 <script runat ="server">
    String LoadDecodedFile(String file)
       String DecodedString = "";
       FileStream fs = new FileStream(file, FileMode.Open);
       StreamReader r = new StreamReader(fs);
       // Position the file pointer at the beginning of the file.
       r.BaseStream.Seek(0, SeekOrigin.Begin);
       // Read the entire file into a string and decode each chunk.  
       while (r.Peek() > -1)
          DecodedString += Server.HtmlDecode(r.ReadLine());
       return DecodedString;
