Encoding.HeaderName Property
Assembly: mscorlib (in mscorlib.dll)
/** @property */ public String get_HeaderName ()
public function get HeaderName () : String
Not applicable.
Property Value
A name for the current Encoding to use with mail agent header tags. -or- An empty string (""), if the current Encoding cannot be used.If your application needs an encoding for a header name, it should call GetEncoding with the HeaderName property. Often the method retrieves a different encoding from the test encoding furnished in the call. Generally only e-mail applications need to retrieve such an encoding.
Note that WebName returns the name to use to describe an encoding. The HeaderName property defines a different encoding that might work better for an e-mail application, for example. However, use of the property to define the encoding is not recommended.
The following code example retrieves the different names for each encoding and displays the encodings with one or more names that are different from EncodingInfo.Name. It displays EncodingName but does not compare against it.
using namespace System; using namespace System::Text; int main() { // Print the header. Console::Write( "Name " ); Console::Write( "CodePage " ); Console::Write( "BodyName " ); Console::Write( "HeaderName " ); Console::Write( "WebName " ); Console::WriteLine( "Encoding.EncodingName" ); // For every encoding, compare the name properties with EncodingInfo.Name. // Display only the encodings that have one or more different names. System::Collections::IEnumerator^ myEnum = Encoding::GetEncodings()->GetEnumerator(); while ( myEnum->MoveNext() ) { EncodingInfo ^ ei = safe_cast<EncodingInfo ^>(myEnum->Current); Encoding^ e = ei->GetEncoding(); if ( !ei->Name->Equals( e->BodyName ) || !ei->Name->Equals( e->HeaderName ) || !ei->Name->Equals( e->WebName ) ) { Console::Write( "{0,-18} ", ei->Name ); Console::Write( "{0,-9} ", e->CodePage ); Console::Write( "{0,-18} ", e->BodyName ); Console::Write( "{0,-18} ", e->HeaderName ); Console::Write( "{0,-18} ", e->WebName ); Console::WriteLine( "{0} ", e->EncodingName ); } } } /* This code produces the following output.
