Encoding.WebName Property
When overridden in a derived class, gets the name registered with the Internet Assigned Numbers Authority (IANA) for the current encoding.
Namespace: System.Text
Assembly: mscorlib (in mscorlib.dll)
The WebName property is the same as the Name property.
Note that WebName returns an IANA-registered name for the encoding. The HeaderName property defines a different encoding that might work better for e-mail headers. However, most applications should use WebName instead.
For more information on the IANA, go to www.iana.org.
The Encoding.WebName is the same as the EncodingInfo.Name returned by Encoding.GetEncodings. Some of the web names are duplicates; see the remarks for Encoding.GetEncodings for more information.
The following example includes the WebName in an HTML header.
using System; using System.IO; using System.Text; using System.Web; namespace WebNameExample { public class ExampleClass { public static void Main(string[] args) { // Use UTF8 encoding. Encoding encoding = Encoding.UTF8; StreamWriter writer = new StreamWriter("Encoding.html", false, encoding); writer.WriteLine("<html><head>"); // Write charset attribute to the html file. // The value of charset is returned by the WebName property. writer.WriteLine("<META HTTP-EQUIV=\"Content-Type\" CONTENT=\"text/html; charset=" + encoding.WebName +"\">"); writer.WriteLine("</head><body>"); writer.WriteLine("<p>" + HttpUtility.HtmlEncode(encoding.EncodingName) + "</p>"); writer.WriteLine("</body></html>"); writer.Flush(); writer.Close(); } } } /* This code produces the following output in an HTML file. <html><head> <META HTTP-EQUIV="Content-Type" CONTENT="text/html; charset=utf-8"> </head><body> <p>Unicode (UTF-8)</p> </body></html> */
The following example retrieves the different names for each encoding and displays the encodings with one or more names that are different from EncodingInfo.Name. It displays EncodingName but does not compare against it.
using System; using System.Text; public class SamplesEncoding { public static void Main() { // Print the header. Console.Write( "Name " ); Console.Write( "CodePage " ); Console.Write( "BodyName " ); Console.Write( "HeaderName " ); Console.Write( "WebName " ); Console.WriteLine( "Encoding.EncodingName" ); // For every encoding, compare the name properties with EncodingInfo.Name. // Display only the encodings that have one or more different names. foreach( EncodingInfo ei in Encoding.GetEncodings() ) { Encoding e = ei.GetEncoding(); if (( ei.Name != e.BodyName ) || ( ei.Name != e.HeaderName ) || ( ei.Name != e.WebName )) { Console.Write( "{0,-18} ", ei.Name ); Console.Write( "{0,-9} ", e.CodePage ); Console.Write( "{0,-18} ", e.BodyName ); Console.Write( "{0,-18} ", e.HeaderName ); Console.Write( "{0,-18} ", e.WebName ); Console.WriteLine( "{0} ", e.EncodingName ); } } } } /* This code produces the following output.
