NegotiateStream.CanWrite Property

Gets a Boolean value that indicates whether the underlying stream is writable.

Namespace:  System.Net.Security
Assembly:  System (in System.dll)

public override bool CanWrite { get; }

Property Value

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

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.

The following code example demonstrates displaying the value of this property.

 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);
     }
}
