在 C# 中运行 powershell 命令时会出现错误，“无法调用此函数，因为当前主机未实现它”

我有一个应用程序，用于在 C# 代码中运行 Exchange Powershell 命令，如下所示。这是我用来运行 powershell 命令的相关行的示例。

            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();

到目前为止，这段代码在所有情况下都能完美运行。我尝试运行的脚本（而不是上面的脚本）是为邮箱设置 RetentionPolicy。我尝试运行的脚本如下所示：

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

当我在 powershell 本身中运行此脚本时，它运行良好，但当我尝试使用下面的代码运行它时，我得到错误，“无法调用此函数，因为当前主机未实现它。”

从这个错误来看，在 C# 中运行的命令几乎无法运行 RetentionPolicy 命令，但这没有多大意义。我已经用谷歌搜索过这个并尝试了所有建议的东西，但没有运气。

如果有人知道为什么会发生这种情况，那将会非常有帮助。

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();

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:

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

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."

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.

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