UTF32Encoding::Equals Method (Object^)
.NET Framework (current version)
Determines whether the specified Object is equal to the current UTF32Encoding 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 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 namespace System; using namespace System::Text; void CompareEncodings( UTF32Encoding ^ a, String^ name ); int main() { // Create different instances of UTF32Encoding. UTF32Encoding ^ u32 = gcnew UTF32Encoding; UTF32Encoding ^ u32tt = gcnew UTF32Encoding( true,true ); UTF32Encoding ^ u32tf = gcnew UTF32Encoding( true,false ); UTF32Encoding ^ u32ft = gcnew UTF32Encoding( false,true ); UTF32Encoding ^ u32ff = gcnew 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" ); } void CompareEncodings( UTF32Encoding ^ a, String^ name ) { // Create different instances of UTF32Encoding using the ctor with three parameters.
