UTF8Encoding::GetHashCode Method ()

 

Returns the hash code for the current instance.

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

public:
virtual int GetHashCode() override

Return Value

Type: System::Int32

The hash code for the current instance.

The following example uses the GetHashCode method to return a hash code for UTF8Encoding instances. Notice that the hash code returned by this method depends on the constructor used to create the UTF8Encoding object.

using namespace System;
using namespace System::Text;
int main()
{

   // Many ways to instantiate a UTF8 encoding.
   UTF8Encoding^ UTF8a = gcnew UTF8Encoding;
   Encoding^ UTF8b = Encoding::UTF8;
   Encoding^ UTF8c = gcnew UTF8Encoding( true,true );
   Encoding^ UTF8d = gcnew UTF8Encoding( false,false );

   // But not all are the same.
   Console::WriteLine( UTF8a->GetHashCode() );
   Console::WriteLine( UTF8b->GetHashCode() );
   Console::WriteLine( UTF8c->GetHashCode() );
   Console::WriteLine( UTF8d->GetHashCode() );
}
