BitVector32.Equals Method

Determines whether the specified object is equal to the BitVector32.

Namespace:  System.Collections.Specialized
Assembly:  System (in System.dll)

public override bool Equals(
	Object o
)

Parameters

o
Type: System.Object

The object to compare with the current BitVector32.

Return Value

Type: System.Boolean
true if the specified object is equal to the BitVector32; otherwise, false.

The object o is considered equal to the BitVector32 if the type of o is compatible with the BitVector32 type and if the value of o is equal to the value of Data.

This method is an O(1) operation.

The following code example compares a BitVector32 with another BitVector32 and with an Int32.

using System;
using System.Collections.Specialized;


public class SamplesBitVector32  {

   public static void Main()  {

      // Creates and initializes a BitVector32 with the value 123. 
      // This is the BitVector32 that will be compared to different types.
      BitVector32 myBV = new BitVector32( 123 );

      // Creates and initializes a new BitVector32 which will be set up as sections.
      BitVector32 myBVsect = new BitVector32( 0 );

      // Compares myBV and myBVsect.
      Console.WriteLine( "myBV                 : {0}", myBV.ToString() );
      Console.WriteLine( "myBVsect             : {0}", myBVsect.ToString() );
      if ( myBV.Equals( myBVsect ) )
         Console.WriteLine( "   myBV({0}) equals myBVsect({1}).", myBV.Data, myBVsect.Data );
      else
         Console.WriteLine( "   myBV({0}) does not equal myBVsect({1}).", myBV.Data, myBVsect.Data );
      Console.WriteLine();

      // Assigns values to the sections of myBVsect.
      BitVector32.Section mySect1 = BitVector32.CreateSection( 5 );
      BitVector32.Section mySect2 = BitVector32.CreateSection( 1, mySect1 );
      BitVector32.Section mySect3 = BitVector32.CreateSection( 20, mySect2 );
      myBVsect[mySect1] = 3;
      myBVsect[mySect2] = 1;
      myBVsect[mySect3] = 7;

      // Compares myBV and myBVsect.
      Console.WriteLine( "myBV                 : {0}", myBV.ToString() );
      Console.WriteLine( "myBVsect with values : {0}", myBVsect.ToString() );
      if ( myBV.Equals( myBVsect ) )
         Console.WriteLine( "   myBV({0}) equals myBVsect({1}).", myBV.Data, myBVsect.Data );
      else
         Console.WriteLine( "   myBV({0}) does not equal myBVsect({1}).", myBV.Data, myBVsect.Data );
      Console.WriteLine();

      // Compare myBV with an Int32.
      Console.WriteLine( "Comparing myBV with an Int32: " );
      Int32 myInt32 = 123;
      // Using Equals will fail because Int32 is not compatible with BitVector32. 
      if ( myBV.Equals( myInt32 ) )
         Console.WriteLine( "   Using BitVector32.Equals, myBV({0}) equals myInt32({1}).", myBV.Data, myInt32 );
      else
         Console.WriteLine( "   Using BitVector32.Equals, myBV({0}) does not equal myInt32({1}).", myBV.Data, myInt32 );
      // To compare a BitVector32 with an Int32, use the "==" operator.
      if ( myBV.Data == myInt32 )
         Console.WriteLine( "   Using the \"==\" operator, myBV.Data({0}) equals myInt32({1}).", myBV.Data, myInt32 );
      else
         Console.WriteLine( "   Using the \"==\" operator, myBV.Data({0}) does not equal myInt32({1}).", myBV.Data, myInt32 );

   }

}

/*
This code produces the following output.

myBV                 : BitVector32{00000000000000000000000001111011}
myBVsect             : BitVector32{00000000000000000000000000000000}
   myBV(123) does not equal myBVsect(0).

myBV                 : BitVector32{00000000000000000000000001111011}
myBVsect with values : BitVector32{00000000000000000000000001111011}
   myBV(123) equals myBVsect(123).

Comparing myBV with an Int32:
   Using BitVector32.Equals, myBV(123) does not equal myInt32(123).
   Using the "==" operator, myBV.Data(123) equals myInt32(123).
