EncodingInfo Class


The .NET API Reference documentation has a new home. Visit the .NET API Browser on docs.microsoft.com to see the new experience.

Provides basic information about an encoding.

Namespace:   System.Text
Assembly:  mscorlib (in mscorlib.dll)


public sealed class EncodingInfo


Gets the code page identifier of the encoding.


Gets the human-readable description of the encoding.


Gets the name registered with the Internet Assigned Numbers Authority (IANA) for the encoding.


Gets a value indicating whether the specified object is equal to the current EncodingInfo object.(Overrides Object.Equals(Object).)


Returns a Encoding object that corresponds to the current EncodingInfo object.


Returns the hash code for the current EncodingInfo object.(Overrides Object.GetHashCode().)


Gets the Type of the current instance.(Inherited from Object.)


Returns a string that represents the current object.(Inherited from Object.)

This class is primarily used by the Encoding class. The Encoding.GetEncodings method returns an array of this type.

This class is intended to provide minimal information about an encoding. To obtain additional information, the application should use the GetEncoding method to get an instance of the Encoding class, which contains more comprehensive information about the encoding it represents.

The following example uses the Encoding.GetEncodings method to retrieve an EncodingInfo object for each encoding supported by the .NET Framework. It then displays the value of each encoding's CodePage, Name, and DisplayName property and compares them with the corresponding Encoding names.

using System;
using System.Text;

public class SamplesEncoding  {

   public static void Main()  {

      // Print the header.
      Console.Write( "Info.CodePage      " );
      Console.Write( "Info.Name                    " );
      Console.Write( "Info.DisplayName" );

      // Display the EncodingInfo names for every encoding, and compare with the equivalent Encoding names.
      foreach( EncodingInfo ei in Encoding.GetEncodings() )  {
         Encoding e = ei.GetEncoding();

         Console.Write( "{0,-15}", ei.CodePage );
         if ( ei.CodePage == e.CodePage )
            Console.Write( "    " );
            Console.Write( "*** " );

         Console.Write( "{0,-25}", ei.Name );
         if ( ei.CodePage == e.CodePage )
            Console.Write( "    " );
            Console.Write( "*** " );

         Console.Write( "{0,-25}", ei.DisplayName );
         if ( ei.CodePage == e.CodePage )
            Console.Write( "    " );
            Console.Write( "*** " );




This code produces the following output.
