The following code example shows how to display the names of each check constraint on each AdventureWorks2012 table.

C#

Server srv = new Server("(local)");
Database db = srv.Databases["AdventureWorks2012"];

foreach (Table tb in db.Tables)
{
   foreach (Check ck in tb.Checks)
   {
      Console.WriteLine("The " + tb.Name + " table has the " + ck.ToString() + " check.");
   }
}

Powershell

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

Foreach ($tb in $db.Tables)
{
   Foreach ($ck in $tb.Checks)
   {
      Write-Host "The" $tb.Name "table has the" $ck "check."
   }
}
