C# :base的用法（冒號後面的base）

c# 中關於: base()用法，在此記錄一下，方便查閱

1.this是標識當前資來源物件的，而base是基於父級的。

 

2.base發揮了期靈魂級的作用——多態

 

3.base子類可以訪問父類成員

 

4.base調用父類方法必須重寫父類方法

 

5.base子類建構函式直接存取：base父類構造方法

 

6.base同樣不能用於靜態方法

public abstract class HttpBasedTransport : ClientTransportBase    {        protected HttpBasedTransport(IHttpClient httpClient, string transportName)            : base(httpClient, transportName)        { }    }

父類

public abstract class ClientTransportBase : IClientTransport    {        private readonly IHttpClient _httpClient;        private readonly string _transportName;        private readonly TransportHelper _transportHelper;        private readonly TransportAbortHandler _abortHandler;        private bool _finished = false;        private TransportInitializationHandler _initializationHandler;        [SuppressMessage("Microsoft.Reliability", "CA2000:Dispose objects before losing scope", Justification = "Disposed in the Dispose method.")]        protected ClientTransportBase(IHttpClient httpClient, string transportName)            : this(httpClient, transportName, new TransportHelper(), new TransportAbortHandler(httpClient, transportName))        {        }        internal ClientTransportBase(IHttpClient httpClient, string transportName, TransportHelper transportHelper, TransportAbortHandler abortHandler)        {            if (httpClient == null)            {                throw new ArgumentNullException("httpClient");            }            if (string.IsNullOrWhiteSpace(transportName))            {                throw new ArgumentNullException("transportName");            }            Debug.Assert(transportHelper != null, "transportHelper is null");            Debug.Assert(abortHandler != null, "abortHandler is null");            _httpClient = httpClient;            _transportName = transportName;            _transportHelper = transportHelper;            _abortHandler = abortHandler;        }    }
