SpaceAvailable 属性

获取数据库中的可用空间 (KB)。

命名空间：  Microsoft.SqlServer.Management.Smo
程序集：  Microsoft.SqlServer.Smo（在 Microsoft.SqlServer.Smo.dll 中）

语法

声明
<SfcPropertyAttribute(SfcPropertyFlags.None Or SfcPropertyFlags.Expensive Or SfcPropertyFlags.Standalone)> _
Public ReadOnly Property SpaceAvailable As Double
    Get
用法
Dim instance As Database
Dim value As Double

value = instance.SpaceAvailable

[SfcPropertyAttribute(SfcPropertyFlags.None|SfcPropertyFlags.Expensive|SfcPropertyFlags.Standalone)]
public double SpaceAvailable { get; }

[SfcPropertyAttribute(SfcPropertyFlags::None|SfcPropertyFlags::Expensive|SfcPropertyFlags::Standalone)]
public:
property double SpaceAvailable {
    double get ();
}

[<SfcPropertyAttribute(SfcPropertyFlags.None|SfcPropertyFlags.Expensive|SfcPropertyFlags.Standalone)>]
member SpaceAvailable : float

function get SpaceAvailable () : double

属性值

类型：System. . :: . .Double
一个 Float64 值，该值指定数据库中的可用空间量 (KB)。

注释

The size is specified in KB and should be the same as when the database was originally created unless you have opted to automatically grow or shrink the database. The space allocated in the database can be determined by using the SpaceAvailable property.

示例

VB

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

'Reference the AdventureWorks2008R2 database.
Dim db As Database
db = srv.Databases("AdventureWorks2008R2")

'Display size and space information for the database.
Console.WriteLine("data space usage (KB): " + _
db.DataSpaceUsage.ToString)
Console.WriteLine("index space usage (KB): " + _
db.IndexSpaceUsage.ToString)
Console.WriteLine("space available (KB): " + _
db.SpaceAvailable.ToString)
Console.WriteLine("database size (MB): " + _
db.Size.ToString)

PowerShell

$srv = new-Object Microsoft.SqlServer.Management.Smo.Server("(local)")
$db = New-Object Microsoft.SqlServer.Management.Smo.Database
$db = $srv.Databases.Item("AdventureWorks2008R2")

Write-Host "data space usage (KB):" $db.DataSpaceUsage
Write-Host "index space usage (KB):" $db.IndexSpaceUsage
Write-Host "space available (KB):" $db.SpaceAvailable
Write-Host "database size (MB):" $db.Size
