Assembly:  System (in System.dll)

public override bool IsSigned { get; }

Property Value

Type: System.Boolean
true if the data is signed before being transmitted; otherwise, false.

Data signing helps to protect the integrity of the data; namely, it helps the recipient determine whether the data has been tampered with while in transit.

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

 static void DisplayAuthenticationProperties(NegotiateStream stream)
{
     Console.WriteLine("IsAuthenticated: {0}", stream.IsAuthenticated);
    Console.WriteLine("IsMutuallyAuthenticated: {0}", stream.IsMutuallyAuthenticated);
    Console.WriteLine("IsEncrypted: {0}", stream.IsEncrypted);
    Console.WriteLine("IsSigned: {0}", stream.IsSigned);
    Console.WriteLine("ImpersonationLevel: {0}", stream.ImpersonationLevel);
    Console.WriteLine("IsServer: {0}", stream.IsServer);
}
