如何在PowerShell C#cmdlet中使用WriteProgressCommand？

Question

更新.我cmdlet在Visual Studio 2010中使用C#/ .Net 4.0 创建了一个PowerShell 3.0 .它工作正常.但cmdlet需要一段时间,我想添加一个进度条.

关于WriteProgressCommand的MSDN文档含糊不清.这是链接:http://msdn.microsoft.com/en-us/library/microsoft.powershell.commands.writeprogresscommand.completed(v=vs.85).aspx

下面的代码显示了我想要做的事情.基本上做一些处理ProcessRecord().然后每秒更新进度条.不确定如何显示进度条.救命？

[System.Management.Automation.Cmdlet(System.Management.Automation.VerbsCommon.Get, "StatusBar")]
public class GetStatusBarCommand : System.Management.Automation.PSCmdlet
{
    /// <summary>
    /// Provides a record-by-record processing functionality for the cmdlet.
    /// </summary>
    protected override void ProcessRecord()
    {
        WriteProgressCommand progress = new WriteProgressCommand();

        for (int i = 0; i < 60; i++)
        {
            System.Threading.Thread.Sleep(1000);
            progress.PercentComplete = i;
        }

        progress.Completed = true;
        this.WriteObject("Done.");
        return;
    }
}

// Commented out thanks to Graimer's answer 
// [System.Management.Automation.CmdletAttribute("Write", "Progress")]
// public sealed class WriteProgressCommand : System.Management.Automation.PSCmdlet { }

我已经测试了cmdlet现在开发10分钟并找出了进度条的工作原理.我甚至无法添加WriteProgressCommand类(但后来我又是编程菜鸟).我做的工作虽然如下:

protected override void ProcessRecord()
      {
         ProgressRecord myprogress = new ProgressRecord(1, "Testing", "Progress:");

          for (int i = 0; i < 100; i++)
          {
              myprogress.PercentComplete = i;
              Thread.Sleep(100);
              WriteProgress(myprogress);
          }

             WriteObject("Done.");
      }

ProgressRecord存储进度定义,并调用WriteProgress命令以使用新更新的progressdata更新shell(powershell窗口).构造函数中的"1"只是一个id.
