Encoding.CodePage Encoding.CodePage Encoding.CodePage Encoding.CodePage Property

定義

派生クラスでオーバーライドされた場合、現在の Encoding のコード ページ ID を取得します。When overridden in a derived class, gets the code page identifier of the current Encoding.

public:
 virtual property int CodePage { int get(); };
public virtual int CodePage { get; }
member this.CodePage : int
Public Overridable ReadOnly Property CodePage As Integer

プロパティ値

現在の Encoding のコード ページ ID。The code page identifier of the current Encoding.

次の例では、各エンコードの異なる名前を取得し、とは異なるEncodingInfo.Name1 つ以上の名前のエンコーディングを表示します。The following example retrieves the different names for each encoding and displays the encodings with one or more names that are different from EncodingInfo.Name. 表示さEncodingNameれますが、比較は行われません。It displays EncodingName but does not compare against it.

using namespace System;
using namespace System::Text;

{
   
   // Print the header.

   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 ) )
