Examples

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."
   }
}
