NegotiateStream.CanWrite プロパティ

定義

基になるストリームが書き込み可能かどうかを示す Boolean 値を取得します。Gets a Boolean value that indicates whether the underlying stream is writable.

public:
 virtual property bool CanWrite { bool get(); };
public override bool CanWrite { get; }
member this.CanWrite : bool
Public Overrides ReadOnly Property CanWrite As Boolean

プロパティ値

認証が行われており、基になるストリームが書き込み可能な場合は true。それ以外の場合は falsetrue if authentication has occurred and the underlying stream is writable; otherwise, false.

次のコード例は、このプロパティの値を表示する方法を示しています。The following code example demonstrates displaying the value of this property.

static void DisplayStreamProperties( NegotiateStream^ stream )
{
   Console::WriteLine( L"Can read: {0}", stream->CanRead );
   Console::WriteLine( L"Can write: {0}", stream->CanWrite );
   Console::WriteLine( L"Can seek: {0}", stream->CanSeek );
   try
   {
      
      // If the underlying stream supports it, display the length.
      Console::WriteLine( L"Length: {0}", stream->Length );
   }
   catch ( NotSupportedException^ ) 
   {
      Console::WriteLine( L"Cannot get the length of the underlying stream." );
   }

   if ( stream->CanTimeout )
   {
      Console::WriteLine( L"Read time-out: {0}", stream->ReadTimeout );
      Console::WriteLine( L"Write time-out: {0}", stream->WriteTimeout );
   }
}


 static void DisplayStreamProperties(NegotiateStream stream)
{
     Console.WriteLine("Can read: {0}", stream.CanRead);
     Console.WriteLine("Can write: {0}", stream.CanWrite);
     Console.WriteLine("Can seek: {0}", stream.CanSeek);
     try 
     {
         // If the underlying stream supports it, display the length.
         Console.WriteLine("Length: {0}", stream.Length);
     } catch (NotSupportedException)
     {
             Console.WriteLine("Cannot get the length of the underlying stream.");
     }
     
     if (stream.CanTimeout)
     {
         Console.WriteLine("Read time-out: {0}", stream.ReadTimeout);
         Console.WriteLine("Write time-out: {0}", stream.WriteTimeout);
     }
}

注釈

認証が成功した場合、このプロパティは、基になるストリームの CanWrite プロパティを呼び出すことによって返される値を返します。If successful authentication has occurred, this property returns the value returned by invoking the CanWrite property on the underlying stream. 基になるストリームは、NegotiateStream クラスのインスタンスを作成するときに指定します。The underlying stream is specified when you create an instance of the NegotiateStream class.
