構文

'宣言
Public Property HostName As String
    Get
    Set
'使用
Dim instance As MergePullSubscription
Dim value As String

value = instance.HostName

instance.HostName = value

public string HostName { get; set; }

public:
property String^ HostName {
    String^ get ();

プロパティ値

型: System. . :: . .String
String 値です。

説明

HostName プロパティを取得できるのは、サブスクライバ側の固定サーバー ロール sysadmin のメンバ、またはサブスクリプション データベースの固定データベース ロール db_owner のメンバだけです。

HostName プロパティを設定できるのは、サブスクライバ側の固定サーバー ロール sysadmin のメンバ、またはサブスクリプション データベースの固定データベース ロール db_owner のメンバだけです。

HostName プロパティを取得すると、sp_helpmergepullsubscription を実行したのと同じことになります。

HostName プロパティを設定すると、sp_addmergepullsubscription_agent または sp_changemergepullsubscription を実行したのと同じことになります。

HostName プロパティは、MicrosoftSQL Server 7.0 および MicrosoftSQL Server 2000 のインスタンスでのみ使用できます。

この名前空間、クラス、またはメンバは、Microsoft .NET Framework 2.0 でのみサポートされています。
