示例
The following code example shows how to display each foreign key in the AdventureWorks2008R2 tables.
C#
Server srv = new Server("(local)");
Database db = srv.Databases["AdventureWorks2008R2"];
Foreach (Table tb in db.Tables)
{
foreach (ForeignKey f in tb.ForeignKeys)
{
Console.WriteLine("The " + tb.Name + " table contains the " + f.ToString() + " foreign key.");
}
}
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 $db.Tables)
{
foreach ($f in $tb.ForeignKeys)
{
Write-Host "The" $tb.Name "table contains the" $f "foreign key."
}
}
