Erstellen von mehreren Runspaces

Wenn Sie eine große Anzahl von Runspaces erstellen, empfiehlt es sich, einen Runspace-Pool zu erstellen. Die Verwendung eines System.Management.Automation.Runspaces.RunspacePool-Objekts, anstatt eine große Anzahl einzelner Runspaces mit denselben Merkmalen zu erstellen, kann die Leistung verbessern.

Erstellen und Verwenden eines Runspace-Pools.

Das folgende Beispiel zeigt, wie Sie einen Runspace-Pool erstellen und einen Befehl asynchron in einem Runspace des Pools ausführen.

namespace HostRunspacePool
{
  using System;
  using System.Collections.ObjectModel;
  using System.Management.Automation;
  using System.Management.Automation.Runspaces;

  /// <summary>
  /// This class provides the Main entry point for the Host application.
  /// </summary>
  internal class HostRunspacePool
  {
    /// <summary>
    /// This sample demonstrates the following.
    /// 1. Creating and opening a runspace pool.
    /// 2. Creating a PowerShell object.
    /// 3. Adding commands and arguments to the PowerShell object.
    /// 4. Running the commands asynchronously using the runspace
    ///    of the runspace pool.
    /// </summary>
    /// <param name="args">Parameter is not used.</param>
    private static void Main(string[] args)
    {
      // Create a pool of runspaces.
      using (RunspacePool rsp = RunspaceFactory.CreateRunspacePool())
      {
        rsp.Open();

        // Create a PowerShell object to run the following command.
        //  Get-Process wmi*
        PowerShell gpc = PowerShell.Create();
        // Specify the runspace to use and add commands.
        gpc.RunspacePool = rsp;
        gpc.AddCommand("Get-Process").AddArgument("wmi*");

        // Invoke the command asynchronously.
        IAsyncResult gpcAsyncResult = gpc.BeginInvoke();
        // Get the results of running the command.
        PSDataCollection<PSObject> gpcOutput = gpc.EndInvoke(gpcAsyncResult);

        // Process the output.
        Console.WriteLine("The output from running the command: Get-Process wmi*");
        for (int i= 0; i < gpcOutput.Count; i++)
        {
         Console.WriteLine(
                           "Process Name: {0} Process Id: {1}",
                           gpcOutput[i].Properties["ProcessName"].Value,
                           gpcOutput[i].Properties["Id"].Value);
        }
      } // End using.
    } // End Main entry point.
  } // End HostPs5 class.
}
