NegotiateStream.Length Property

Gets the length of the underlying stream.

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

public override long Length { get; }

Property Value

Type: System.Int64
A Int64 that specifies the length of the underlying stream.

ExceptionCondition
NotSupportedException

Getting the value of this property is not supported when the underlying stream is a NetworkStream.

This property returns the value returned by invoking the Length property on the underlying stream. If the underlying stream is not seekable, this property will typically throw an exception. The run-time type of the underlying stream determines the run-time type of the exception that is thrown.

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);
     }
}
