UTF8Encoding::Equals Method (Object^)

 

Determines whether the specified object is equal to the current UTF8Encoding object.

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

public:
virtual bool Equals(
	Object^ value
) override

Parameters

value
Type: System::Object^

The object to compare with the current instance.

Return Value

Type: System::Boolean

true if value is an instance of UTF8Encoding and is equal to the current object; otherwise, false.

Two UTF8Encoding objects are considered equal if all of the following conditions are true:

  • 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 uses the Equals method to test whether the current UTF8Encoding object is equal to a different UTF8Encoding object. Four UTF8Encoding objects are created and compared and the results of the comparisons are displayed.

using namespace System;
using namespace System::Text;
void DescribeEquivalence( Boolean isEquivalent )
{
   Console::WriteLine( "{0} equivalent encoding.", (isEquivalent ? (String^)"An" : "Not an") );
}

int main()
{
   UTF8Encoding^ utf8 = gcnew UTF8Encoding;
   UTF8Encoding^ utf8true = gcnew UTF8Encoding( true );
   UTF8Encoding^ utf8truetrue = gcnew UTF8Encoding( true,true );
   UTF8Encoding^ utf8falsetrue = gcnew UTF8Encoding( false,true );
   DescribeEquivalence( utf8->Equals( utf8 ) );
   DescribeEquivalence( utf8->Equals( utf8true ) );
   DescribeEquivalence( utf8->Equals( utf8truetrue ) );
   DescribeEquivalence( utf8->Equals( utf8falsetrue ) );
   DescribeEquivalence( utf8true->Equals( utf8 ) );
   DescribeEquivalence( utf8true->Equals( utf8true ) );
   DescribeEquivalence( utf8true->Equals( utf8truetrue ) );
   DescribeEquivalence( utf8true->Equals( utf8falsetrue ) );
   DescribeEquivalence( utf8truetrue->Equals( utf8 ) );
   DescribeEquivalence( utf8truetrue->Equals( utf8true ) );
   DescribeEquivalence( utf8truetrue->Equals( utf8truetrue ) );
   DescribeEquivalence( utf8truetrue->Equals( utf8falsetrue ) );
   DescribeEquivalence( utf8falsetrue->Equals( utf8 ) );
   DescribeEquivalence( utf8falsetrue->Equals( utf8true ) );
   DescribeEquivalence( utf8falsetrue->Equals( utf8truetrue ) );
   DescribeEquivalence( utf8falsetrue->Equals( utf8falsetrue ) );
}
