NegotiateStream.CanWrite Property

Definition

Namespace:

System.Net.Security

Assembly:

System.Net.Security.dll

Source:

NegotiateStream.cs

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

Property Value

Boolean

true if authentication has occurred and the underlying stream is writable; otherwise, false.

Examples

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);
     }
}

Remarks

If successful authentication has occurred, this property returns the value returned by invoking the CanWrite property on the underlying stream. The underlying stream is specified when you create an instance of the NegotiateStream class.
