A DataTable system object value that contains an enumerated list of information about the available instances of SQL Server on the specified computer.

The table describes the different columns of the returned DataTable.

Column	Data type	Description
Name	String	The name of the instance of SQL Server.
Server	String	The name of the server on which the instance of SQL Server is installed.
Instance	String	The instance of SQL Server.
IsClustered	Boolean	A Boolean value that is true if the instance is participating in failover clustering, or false if it is not.
Version	String	The version of the instance of SQL Server.
IsLocal	Boolean	A Boolean value that is true if the instance is local, or false if the instance is remote.

备注

已更新的文本：

The computer that is running the instance SQL Server might not receive responses to the EnumAvailableSqlServers method in a timely manner. The returned list might not show all the available instances of SQL Server on the network. When you call the EnumAvailableSqlServers method in subsequent tries, more servers might become visible on the network.

This method fails to list the local instance if a firewall is operating on the server. The firewall blocks any broadcast traffic issued when the method is called, even if the sender is from local machine.

仅 Microsoft .NET Framework 的 2.0 版本支持此命名空间、类或成员。
