UnicodeEncoding::Equals Method (Object^)
Determines whether the specified Object is equal to the current UnicodeEncoding object.
Assembly: mscorlib (in mscorlib.dll)
Parameters
- value
-
Type:
System::Object^
The object to compare with the current object.
Return Value
Type: System::Booleantrue if value is an instance of UnicodeEncoding and is equal to the current object; otherwise, false.
Two UnicodeEncoding objects are considered equal if all of the following conditions are true:
Both objects use the same byte order (little-endian or big-endian).
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 demonstrates how to use the Equals method to test whether the current UnicodeEncoding object is equal to a different UnicodeEncoding object. Five UnicodeEncoding 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() { // Create a UnicodeEncoding without parameters. UnicodeEncoding^ unicode = gcnew UnicodeEncoding; // Create a UnicodeEncoding to support little-endian Byte ordering // and include the Unicode Byte order mark. UnicodeEncoding^ unicodeLittleEndianBOM = gcnew UnicodeEncoding( false,true ); // Compare this UnicodeEncoding to the UnicodeEncoding without parameters. DescribeEquivalence( unicode->Equals( unicodeLittleEndianBOM ) ); // Create a UnicodeEncoding to support little-endian Byte ordering // and not include the Unicode Byte order mark. UnicodeEncoding^ unicodeLittleEndianNoBOM = gcnew UnicodeEncoding( false,false ); // Compare this UnicodeEncoding to the UnicodeEncoding without parameters. DescribeEquivalence( unicode->Equals( unicodeLittleEndianNoBOM ) ); // Create a UnicodeEncoding to support big-endian Byte ordering // and include the Unicode Byte order mark. UnicodeEncoding^ unicodeBigEndianBOM = gcnew UnicodeEncoding( true,true ); // Compare this UnicodeEncoding to the UnicodeEncoding without parameters. DescribeEquivalence( unicode->Equals( unicodeBigEndianBOM ) ); // Create a UnicodeEncoding to support big-endian Byte ordering // and not include the Unicode Byte order mark. UnicodeEncoding^ unicodeBigEndianNoBOM = gcnew UnicodeEncoding( true,false ); // Compare this UnicodeEncoding to the UnicodeEncoding without parameters. DescribeEquivalence( unicode->Equals( unicodeBigEndianNoBOM ) ); }
