Encoding.WindowsCodePage プロパティ

定義

派生クラスでオーバーライドされた場合、現在のエンコーディングに最も厳密に対応する Windows オペレーティング システムのコード ページを取得します。

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

プロパティ値

Int32

現在の Encoding に最も厳密に対応する、Windows オペレーティング システムのコード ページ。

次の例では、各エンコーディングに最も厳密に対応する Windows コードページを特定します。

using namespace System;
using namespace System::Text;
int main()
{
   
   // Print the header.
   Console::Write( "CodePage identifier and name     " );
   Console::WriteLine( "WindowsCodePage" );
   
   // For every encoding, get the Windows code page for it.
   System::Collections::IEnumerator^ myEnum = Encoding::GetEncodings()->GetEnumerator();
   while ( myEnum->MoveNext() )
   {
      EncodingInfo ^ ei = safe_cast<EncodingInfo ^>(myEnum->Current);
      Encoding^ e = ei->GetEncoding();
      Console::Write( "{0,-6} {1,-25} ", ei->CodePage, ei->Name );
      Console::Write( "{0,-6} ", e->WindowsCodePage );
      
      // Mark the ones that are different.
      if ( ei->CodePage != e->WindowsCodePage )
            Console::Write( "*" );
      Console::WriteLine();
   }
}
