如何与 powershell 中的 .NET 对象方法进行交互？

Question

如何在 powershell（Elasticsearch NEST .NET 客户端）中调用 .NET 对象的方法。这是 NEST 客户端的 .NET 代码的基本示例，我正在尝试编写等效的 PS，但我无法设置对象值。这甚至可能与 powershell 中的 .NET 对象有关吗？

.NET

var config = new Nest.ConnectionSettings(pool, httpConnection)
.DefaultIndex("employee_data"); //complete extensions omitted for brevity

Powershell

$config = new-object -Type Nest.ConnectionSettings($pool, $httpConnection)
$config.DefaultIndex("mate")
Method invocation failed because [Nest.ConnectionSettings] does not contain a method named 'DefaultIndex'.
