屬性值

型別：System. . :: . .Boolean
Boolean 值，這個值會指定資料表是否至少有定義一個索引。
如果為 True，則表示資料表有定義索引，否則為 False (預設值)。

範例

The following code example shows how to check each table in the AdventureWorks2008R2 database to see if it has an index.

C#

Server srv = new Server("(local)");
Database db = srv.Databases["AdventureWorks2008R2"];

Foreach (Table tb in db.Tables) 
{
   Console.WriteLine("The " + tb.Name + " table has an index:" + tb.HasIndex.ToString());
}

Powershell

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

Foreach ($tb in $db.Tables) 
{
   Write-Host "The" $tb.Name "table has an index:" $tb.HasIndex
}
