声明
<SfcObjectAttribute(SfcContainerRelationship.ObjectContainer, SfcContainerCardinality.ZeroToAny,  _
    GetType(SymmetricKey))> _
Public ReadOnly Property SymmetricKeys As SymmetricKeyCollection 
    Get
用法
Dim instance As Database 
Dim value As SymmetricKeyCollection 

value = instance.SymmetricKeys
[SfcObjectAttribute(SfcContainerRelationship.ObjectContainer, SfcContainerCardinality.ZeroToAny, 
    typeof(SymmetricKey))]
public SymmetricKeyCollection SymmetricKeys { get; }
[SfcObjectAttribute(SfcContainerRelationship::ObjectContainer, SfcContainerCardinality::ZeroToAny, 
    typeof(SymmetricKey))]
public:
property SymmetricKeyCollection^ SymmetricKeys {
    SymmetricKeyCollection^ get ();
}
[<SfcObjectAttribute(SfcContainerRelationship.ObjectContainer, SfcContainerCardinality.ZeroToAny, 
    typeof(SymmetricKey))>]
member SymmetricKeys : SymmetricKeyCollection
function get SymmetricKeys () : SymmetricKeyCollection

属性值

类型:Microsoft.SqlServer.Management.Smo.SymmetricKeyCollection
A SymmetricKeyCollection object that represents all the symmetric keys defined on the database.

注释

Specific symmetric keys can be referenced by using this collection by specifying the name of the symmetric key. To add a new symmetric key to the collection, call the symmetric key constructor SymmetricKey, or its overload.

示例

VB

'Connect to the local, default instance of SQL Server.
Dim srv As Server
srv = New Server

'Reference the AdventureWorks2012 database.
Dim db As Database
db = srv.Databases("AdventureWorks2012")

'Display all the symmetric keys in the database.
Dim sk As SymmetricKey
For Each sk In db.SymmetricKeys
   Console.WriteLine(sk.Name)
Next

PowerShell

$srv = new-Object Microsoft.SqlServer.Management.Smo.Server("(local)")
$db = New-Object Microsoft.SqlServer.Management.Smo.Database
$db = $srv.Databases.Item("AdventureWorks2012")

Foreach ($sk in $db.SymmetricKeys)
{
   Write-Host $sk.Name
}
