将实时输出从 Exchange Powershell 发送到 C# 中的文本框

Question

>我有一个Exchange Powershell脚本，可以将电子邮件从一个帐户移动到另一个帐户。 当您通过Powershell调用代码时，它会为您提供实时数据统计信息。 我怎样才能捕获它并将其输入到一个文本框中，该文本框将提供该"实时提要"。提前感谢任何帮助。

    public void RunPowerShell()
    {            
        Cursor.Current = Cursors.WaitCursor;
        RunspaceConfiguration rsConfig = RunspaceConfiguration.Create();
        PSSnapInException snapInException = null;
        Runspace runSpace;
        //create the runspace
        runSpace = RunspaceFactory.CreateRunspace(rsConfig);
        //insert try here
        runSpace.Open();
        //for exchange 2010 use "Microsoft.Exchange.Management.PowerShell.E2010"
        rsConfig.AddPSSnapIn("Microsoft.Exchange.Management.PowerShell.Admin", out snapInException);
        //set up the pipeline to run the powershell command 
        Pipeline pipeLine = runSpace.CreatePipeline();
        //create the scripts to use
        String sScript = "Add-MailboxPermission -Identity " + FromEmailAccount.Text + " -User Administrator -AccessRights FullAccess";
        String sScript1 = "Add-MailboxPermission -Identity " + ToEmailAccount.Text + " -User Administrator -AccessRights FullAccess";
        String sScript2 = "Export-Mailbox -Identity " + FromEmailAccount.Text + " -TargetMailbox " + ToEmailAccount.Text + " -TargetFolder " + FromEmailAccount.Text + " -Confirm:$false";
        //invoke the scripts
        pipeLine.Commands.AddScript(sScript);
        pipeLine.Commands.AddScript(sScript1);
        pipeLine.Commands.AddScript(sScript2);
        Collection<PSObject> commandResults = pipeLine.Invoke();
        //loop through the results of the command and load the ?
        foreach (PSObject results in commandResults)
        {
            richTextBox1.Text = results.ToString();
            //MessageBox.Show(results.Properties["DisplayName"].Value.ToString(),@"Name");
        }
        //close the pipelin and runspace
        pipeLine.Dispose();
        runSpace.Close();
        //create completed message
        MessageBox.Show(@"Email migration is complete", @"Done");
        Cursor.Current = Cursors.Default;
    }

Answer 1

在行之后

pipeLine.Commands.AddScript(sScript2);

尝试添加

pipeLine.Commands.Add("out-string");

我认为这将获取所有输出（PSObjects）并将它们转换为字符串。这可能更容易在文本框中分析和显示。

下面是如何更新 GUI 的示例。在scriptText变量中，我定义了两个PowerShell函数。您需要更改第一个函数，以具有启动邮箱导出的代码。然后，您需要更改第二个函数来查询导出并找出完成的百分比。

                    $script:finishtime = (get-date).addminutes(1)
                }
                function getPercentDone() {
                    $timeleft = new-timespan $(get-date) $finishtime

            PowerShell psExec = PowerShell.Create();
            psExec.AddScript(scriptText);
            // Start the export
            psExec.Invoke();
            // Flush the currently added commands
            psExec.Commands.Clear();
            Collection<PSObject> results;
            Collection<ErrorRecord> errors;
            int percent = 0;
            // Report on the export
            while (percent < 100)
            {

                Thread.Sleep(1000);
                psExec.AddScript("getPercentDone | out-string");
                results = psExec.Invoke();
                errors = psExec.Streams.Error.ReadAll();
                foreach (PSObject obj in results)
                {
                    Int32.TryParse(obj.ToString(), out percent);
                    worker.ReportProgress(percent);
                }
            }
        }
        private void bw_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
        {
            if ((e.Cancelled == true))
            {
                textbox1.Text = "Canceled!";
            }
            else if (!(e.Error == null))
            {
                textbox1.Text = ("Error: " + e.Error.Message);
            }
            else
            {
                textbox1.Text = "Done!";
            }
        }
    }
}

我想你想把PowerShell代码改成这样：

function startExport() {
    $script:exportid = new-mailboxexportrequest -mailbox "John Doe" -filepath  '\filesharejohn.doe.pst' -baditemlimit $baditemlimit
    # Give the export some time to get settled
    start-sleep 10
}
function getPercentDone() {
    $export = get-mailboxexportrequest $script:exportid
    $exportstats = $export | get-mailboxexportrequeststatistics
    return $exportstats.PercentComplete
}

但我还没有测试过。
