部分資訊涉及發行前產品，在發行之前可能會有大幅修改。 Microsoft 對此處提供的資訊，不做任何明確或隱含的瑕疵擔保。
取得從 FTP 伺服器傳送的最新狀態碼。
public:
property System::Net::FtpStatusCode StatusCode { System::Net::FtpStatusCode get(); };C#
public System.Net.FtpStatusCode StatusCode { get; }member this.StatusCode : System.Net.FtpStatusCodePublic ReadOnly Property StatusCode As FtpStatusCodeFtpStatusCode 值，指示與回應一起傳回的最新狀態碼。
下列程式代碼範例會將檔案上傳至伺服器，並顯示狀態。

屬性傳 StatusCode 回的值會包含在屬性中 StatusDescription 。 當您下載數據時，FTP 伺服器會傳回狀態代碼變更 StatusCode 的值。 呼叫 GetResponse 方法之後， StatusCode 包含中繼狀態代碼。 當您呼叫 Close 方法時， StatusCode 會包含最終狀態。
