UTF32Encoding.Equals Method (Object)

 

Determines whether the specified Object is equal to the current UTF32Encoding object.

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

public override bool Equals(
	object value
)

Parameters

value
Type: System.Object

The Object to compare with the current object.

Return Value

Type: System.Boolean

true if value is an instance of UTF32Encoding and is equal to the current object; otherwise, false.

Two UTF32Encoding objects are considered equal if all of the following conditions are true:

  • Both objects use the same byte order.

  • Both objects provide the byte order mark, or both do not.

  • Both objects use the same encoder fallback.

  • Both objects use the same decoder fallback.

The following example creates UTF32Encoding objects using different parameter values and then checks them for equality.

using System;
using System.Text;

public class SamplesUTF32Encoding  {

   public static void Main()  {

      // Create different instances of UTF32Encoding.
      UTF32Encoding u32   = new UTF32Encoding();
      UTF32Encoding u32tt = new UTF32Encoding( true, true );
      UTF32Encoding u32tf = new UTF32Encoding( true, false );
      UTF32Encoding u32ft = new UTF32Encoding( false, true );
      UTF32Encoding u32ff = new UTF32Encoding( false, false );

      // Compare these instances with instances created using the ctor with three parameters.
      CompareEncodings( u32,   "u32  " );
      CompareEncodings( u32tt, "u32tt" );
      CompareEncodings( u32tf, "u32tf" );
      CompareEncodings( u32ft, "u32ft" );
      CompareEncodings( u32ff, "u32ff" );

   }


   public static void CompareEncodings( UTF32Encoding a, String name )  {

      // Create different instances of UTF32Encoding using the ctor with three parameters.
      UTF32Encoding u32ttt = new UTF32Encoding( true, true, true );
      UTF32Encoding u32ttf = new UTF32Encoding( true, true, false );
      UTF32Encoding u32tft = new UTF32Encoding( true, false, true );
      UTF32Encoding u32tff = new UTF32Encoding( true, false, false );
      UTF32Encoding u32ftt = new UTF32Encoding( false, true, true );
      UTF32Encoding u32ftf = new UTF32Encoding( false, true, false );
      UTF32Encoding u32fft = new UTF32Encoding( false, false, true );
      UTF32Encoding u32fff = new UTF32Encoding( false, false, false );

      // Compare the specified instance with each of the instances that were just created.
      Console.WriteLine( "{0} and u32ttt : {1}", name, a.Equals( u32ttt ) );
      Console.WriteLine( "{0} and u32ttf : {1}", name, a.Equals( u32ttf ) );
      Console.WriteLine( "{0} and u32tft : {1}", name, a.Equals( u32tft ) );

      Console.WriteLine( "{0} and u32fft : {1}", name, a.Equals( u32fft ) );
      Console.WriteLine( "{0} and u32fff : {1}", name, a.Equals( u32fff ) );

   }
