NegotiateStream.CanRead 屬性

定義

命名空間:

System.Net.Security

組件:

System.Net.Security.dll

來源:

NegotiateStream.cs

取得 Boolean 值，指示基礎資料流是否可讀取。

public:
 virtual property bool CanRead { bool get(); };

public override bool CanRead { get; }

member this.CanRead : bool

Public Overrides ReadOnly Property CanRead As Boolean

屬性值

Boolean

如果執行驗證且基礎資料流可讀取，則為 true，否則為 false。

範例

下列程式代碼範例示範如何顯示這個屬性的值。

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);
     }
}

備註

如果驗證成功，這個屬性會傳回在基礎數據流上叫 CanRead 用 屬性所傳回的值。 當您建立 類別的 NegotiateStream 實例時，會指定基礎數據流。
