Powershell method with Action parameter

Question

How to execute a method that has Action<T> as a parameter in Powershell?

upgradeEngine.Configure(c => c.ScriptExecutor.ExecutionTimeoutSeconds = 15 * 60);

C# code:

var upgradeEngine = DeployChanges.To
    .SqlDatabase(connectionString)
    .WithScriptsEmbeddedInAssembly(Assembly.GetExecutingAssembly())
    .LogToConsole();

//this line
upgradeEngine.Configure(c => c.ScriptExecutor.ExecutionTimeoutSeconds = 15 * 60);

//this line
upgradeEngine.Build();

Add-Type -Path (Join-Path -Path $currentPath -ChildPath 'x:\location\of\DbUp.dll')

$dbUp = [DbUp.DeployChanges]::To
$dbUp = [SqlServerExtensions]::SqlDatabase($dbUp, $connectionString)
$dbUp = [StandardExtensions]::WithScriptsFromFileSystem($dbUp, $scriptPath)
$dbUp = [StandardExtensions]::LogToConsole($dbUp)
$upgradeResult = $dbUp.Build().PerformUpgrade()

I'm not sure what you mean by that, but the delegate accepts a parameter `$i` and uses it. — GSerg, Apr 16 '17 at 10:25

Construct a ScriptBlock with the appropriate signature and cast it as [Action[T]]

$delegate = [System.Action[DbUp.Builder.UpgradeConfiguration]]{
  param([DbUp.Builder.UpgradeConfiguration]$c)
  $c.ScriptExecutor.ExecutionTimeoutSeconds = 15 * 60
}
$DbUp.Configure($delegate)
