如何：建立發送訂閱 (RMO 程式設計)

您可以使用「複寫管理物件」(RMO) 以程式設計的方式建立發送訂閱。用於建立發送訂閱的 RMO 類別依該訂閱所屬的發行集類型而定。

安全性注意事項
可能的話，會在執行階段提示使用者輸入安全性認證。如果您必須儲存認證，請使用 Microsoft Windows .NET Framework 提供的密碼編譯服務。

若要建立快照式或交易式發行集的發送訂閱

使用 ServerConnection 類別建立到「發行者」的連接。
使用步驟 1 中的「發行者」連接建立 TransPublication 類別的執行個體。指定 Name、DatabaseName 和 ConnectionContext。
呼叫 LoadProperties 方法。如果此方法傳回 false，則表示步驟 2 中指定的屬性不正確，或伺服器上不存在該發行集。
在 Attributes 屬性和 AllowPush 之間執行位元運算邏輯 AND (Visual C# 中的 & 和 Visual Basic 中的 And)。如果結果為 None，則將 Attributes 設為 Attributes 和 AllowPush 之間位元運算邏輯 OR (Visual C# 中的 | 和 Visual Basic 中的 Or) 的結果。然後呼叫 CommitPropertyChanges 以啟用發送訂閱。
如果訂閱資料庫不存在，可使用 Database 類別建立它。如需詳細資訊，請參閱＜建立、改變和移除資料庫＞。
建立 TransSubscription 類別的執行個體。
設定下列訂閱屬性：
- 將 ConnectionContext 設為到步驟 1 中建立之「發行者」的 ServerConnection。
- 將 SubscriptionDBName 設為訂閱資料庫的名稱。
- 將 SubscriberName 設為「訂閱者」的名稱。
- 將 DatabaseName 設為發行集資料庫的名稱。
- 將 PublicationName 設為發行集的名稱。
- SynchronizationAgentProcessSecurity 的 Login 和 Password (或 SecurePassword) 欄位，為「散發代理程式」在「散發者」上執行時所使用的 Microsoft Windows 帳戶提供認證。此帳戶用於建立到「散發者」的本機連接，以及使用「Windows 驗證」建立遠端連接。
  
  [!附註]
  
  當訂閱是由 sysadmin 固定伺服器角色的成員建立時，不需要設定 SynchronizationAgentProcessSecurity，但還是建議您對其進行設定。在這種情況下，代理程式會模擬「」帳戶。如需詳細資訊，請參閱＜複寫代理程式安全性模型＞。
- (選擇性) CreateSyncAgentByDefault 的 true 值 (預設值)，以建立用於同步處理訂閱的代理程式作業。如果指定 false，則只能以程式設計的方式同步處理訂閱。
- (選擇性) 在使用「SQL Server 驗證」連接到「訂閱者」時，設定 SubscriberSecurity 的 SqlStandardLogin 和 SqlStandardPassword (或 SecureSqlStandardPassword) 欄位。

呼叫 Create 方法。

安全性注意事項
當利用遠端「散發者」來設定「發行者」時，提供給所有屬性的值 (包括 SynchronizationAgentProcessSecurity) 都會以純文字的方式傳給「散發者」。您應該先加密「發行者」及其遠端「散發者」之間的連接，再呼叫 Create 方法。如需詳細資訊，請參閱＜加密 SQL Server 的連接＞。

若要建立合併式發行集的發送訂閱

使用 ServerConnection 類別建立到「發行者」的連接。
使用步驟 1 中的「發行者」連接建立 MergePublication 類別的執行個體。指定 Name、DatabaseName 和 ConnectionContext。
呼叫 LoadProperties 方法。如果此方法傳回 false，則表示步驟 2 中指定的屬性不正確，或伺服器上不存在該發行集。
在 Attributes 屬性和 AllowPush 之間執行位元運算邏輯 AND (Visual C# 中的 & 和 Visual Basic 中的 And)。如果結果為 None，則將 Attributes 設為 Attributes 和 AllowPush 之間位元運算邏輯 OR (Visual C# 中的 | 和 Visual Basic 中的 Or) 的結果。然後呼叫 CommitPropertyChanges 以啟用發送訂閱。
如果訂閱資料庫不存在，可使用 Database 類別建立它。如需詳細資訊，請參閱＜建立、改變和移除資料庫＞。
建立 MergeSubscription 類別的執行個體。
設定下列訂閱屬性：
- 將 ConnectionContext 設為到步驟 1 中建立之「發行者」的 ServerConnection。
- 將 SubscriptionDBName 設為訂閱資料庫的名稱。
- 將 SubscriberName 設為「訂閱者」的名稱。
- 將 DatabaseName 設為發行集資料庫的名稱。
- 將 PublicationName 設為發行集的名稱。
- SynchronizationAgentProcessSecurity 的 Login 和 Password (或 SecurePassword) 欄位，為「合併代理程式」在「散發者」上執行時所使用的 Microsoft Windows 帳戶提供認證。此帳戶用於建立到「散發者」的本機連接，以及使用「Windows 驗證」建立遠端連接。
  
  [!附註]
  
  當訂閱是由 sysadmin 固定伺服器角色的成員建立時，不需要設定 SynchronizationAgentProcessSecurity，但還是建議您對其進行設定。在這種情況下，代理程式會模擬「SQL Server 代理程式」帳戶。如需詳細資訊，請參閱＜複寫代理程式安全性模型＞。
- (選擇性) CreateSyncAgentByDefault 的 true 值 (預設值)，以建立用於同步處理訂閱的代理程式作業。如果指定 false，則只能以程式設計的方式同步處理訂閱。
- (選擇性) 在使用「SQL Server 驗證」連接到「訂閱者」時，設定 SubscriberSecurity 的 SqlStandardLogin 和 SqlStandardPassword (或 SecureSqlStandardPassword) 欄位。
- (選擇性) 在使用「SQL Server 驗證」連接到「發行者」時，設定 PublisherSecurity 的 SqlStandardLogin 和 SqlStandardPassword (或 SecureSqlStandardPassword) 欄位。

呼叫 Create 方法。

安全性注意事項
利用遠端「散發者」來建立「發行者」上的發送訂閱時，提供給所有屬性的值 (包括 SynchronizationAgentProcessSecurity) 都會以純文字的方式傳給「散發者」。您應該先加密「發行者」及其遠端「散發者」之間的連接，再呼叫 Create 方法。如需詳細資訊，請參閱＜加密 SQL Server 的連接＞。
