public string DatabaseName { get; set; }

Valore proprietà

Tipo: System..::..String
A String value.

DatabaseName is a required property and must be set before the subscription is created on the server. Once the subscription exists on the server, the DatabaseName property cannot be changed.

The DatabaseName property can only be retrieved by members of the sysadmin fixed server role at the Subscriber or by members of the db_owner fixed database role on the subscription database.

The DatabaseName property can only be set by members of the sysadmin fixed server role at the Subscriber or by members of the db_owner fixed database role on the subscription database.

Retrieving the DatabaseName property is equivalent to executing sp_helppullsubscription (Transact-SQL) or sp_helpmergepullsubscription (Transact-SQL).

Setting the DatabaseName property is equivalent to executing sp_addpullsubscription (Transact-SQL) or sp_addmergepullsubscription (Transact-SQL).

The DatabaseName property is available with SQL Server 7.0, SQL Server 2000, and SQL Server 2005.

This namespace, class, or member is supported only in version 2.0 of the .NET Framework.
