C# .NET - Which OOPS concept is used

SmtpClient smtp_Client = new SmtpClient ();

smtp_Client.Credentials = new NetworkCredential("a", "b"); 

here in above in 2nd line ,
  smtp_Client is the object of class SmtpClient but  its assigned with class  NetworkCredential 

 what OOPS concept is used,
can somebody explain

Thanks 

In simple words here in the credentials they act like properties that gets or sets the value thus achieving encapsulation
the state of your type with properties

The smtp_client is not assigned with Network Credential. The Credentials property of the  smtp_client object is assigned to the NetworkCredential.

SmtpClient.Credentials Property needs a value of type System.Net.ICredentialsByHost. You can pass any class objects that implements this interface. NetworkCredential class happens to be one such class.

NetworkCredential has done something that can be termed as "Interface inheritance" or "Interface implementation".
