运行在C＃中有错误的PowerShell命令，＆QUOT;不能调用这个函数，因为目前的宿主，并不能实现它与QUOT; [英] Running a powershell command in C# errors with, "Cannot invoke this function because the current host does not implement it"

问题描述

我有，我用它来运行Exchange的Powershell里面C＃code命令，如下面的应用程序。这是相关的线I用于运行powershell命令的一个例子。

I have an application that I use to run Exchange Powershell commands inside C# code like below. This is an example of the relevant lines I use to run the powershell command.

            RunspaceConfiguration rsConfig = RunspaceConfiguration.Create();
        PSSnapInException snapInException = null;

        //load Exchange shell
        rsConfig.AddPSSnapIn("Microsoft.Exchange.Management.PowerShell.E2010", out snapInException); 
        Runspace runSpace = RunspaceFactory.CreateRunspace(rsConfig);

        //open runspace
        runSpace.Open();

        //setup pipeline
        Pipeline pipeLine = runSpace.CreatePipeline();
        String sScript = "get-mailbox -identity 'rj'";

        //add script to pipeline
        pipeLine.Commands.AddScript(sScript);

        //run the script
        pipeLine.Invoke();
        pipeLine.Dispose();

这code可以完美运行在所有的情况下，一直到现在。脚本我试图运行，而不是上面那个是设置的RetentionPolicy邮箱。我试图运行该脚本是这样的：

This code works perfect in all cases until now. the script I am trying to run instead of the one above is to set the RetentionPolicy for a mailbox. The script I am trying to run looks like this:

设置邮箱-IdentityRJ-RetentionPolicy'主校区保留策略

Set-Mailbox -Identity 'rj' -RetentionPolicy 'Main Campus Retention Policy'

当我运行这个在PowerShell中它本身完美的作品，但是当我尝试使用code以下我得到的错误来运行它，不能调用此函数，因为目前的主机没有实现它。

When I run this in powershell itself it works perfectly but when I try to run it using the code below I get the error, "Cannot invoke this function because the current host does not implement it."

从这个错误，它似乎像一个运行在C＃中不能运行的RetentionPolicy命令的命令，但是这并没有多大意义。我用Google搜索这一点，并尝试了所有建议，但没有运气。

From this error, it almost seems like the command that runs in C# cannot run the RetentionPolicy command but that doesn't make much sense. I have Googled this and tried everything suggested but no luck.

如果有人知道为什么会这样，那将是非常有益的。

If anyone knows why this is happening, it would be very helpful.

推荐答案

如果该命令通常会提示进行确认，那么你将需要：

If that command would normally prompt for confirmation then you will need to either:

• 设置 -Confirm：$假作为一个参数（也可能是 -Force 为好）
• 设置 $确认preference =无调用设置邮箱（也可能是之前 -Force 太）
• 创建一个主机和落实确认功能; - ）

• Set -Confirm:$false as a parameter (and possibly -Force as well)
• Set $ConfirmPreference = "None" before calling Set-Mailbox (and possibly -Force too)
• Create a Host and implement the Confirm functionality ;-)
