Question

我正在开发一个将部署在Exchange 2013服务器上的C＃Web服务。此服务将负责运行powershell命令以配置Exchange。

我通过像这样创建的运行空间连接

const string shellUri = "http://schemas.microsoft.com/powershell/microsoft.exchange";
var uri = new Uri(_exchangeConnectionUri);
var credentials = (PSCredential)null; // Windows authentication
var connectionInfo = new WSManConnectionInfo(uri, shellUri, credentials);
connectionInfo.AuthenticationMechanism = AuthenticationMechanism.Kerberos;
var runspace = RunspaceFactory.CreateRunspace(connectionInfo);

使用此运行空间，我可以在服务器上运行基本的PowerShell命令。

get-mailbox -ResultSize unlimited

但是运行更复杂的命令会给我带来错误（如果直接通过powershell运行，这确实有效）

get-mailbox -ResultSize unlimited | where {$_.emailaddresses -like "*test.com"}

At line:1 char:43
+ get-mailbox -ResultSize unlimited | where {$_.emailaddresses -like "*test.com ...
+                                           ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Script block literals are not allowed in restricted language mode or a Data section.

+                                            ~~~~~~~~~~~~~~~~~

A variable that cannot be referenced in restricted language mode or a Data section is being referenced. Variables that can be referenced include the following: $PSCulture, $PSUICulture, $true, $false, and  $null.

搜索后，我发现我可能需要注册一个新的PSSessionConfiguration，并确保脚本在PSLanguageMode = FullLanguage下运行。 See this post

我尝试这样做，但是一旦我将shellUri更改为http://schemas.microsoft.com/powershell/MyConfigName，我就会收到以下错误。

The WS-Management service cannot process the request.
Cannot find the MyConfigName session configuration in the WSMan: drive on the ComputerName computer.

使用以下shelllUri给了我同样的错误http://schemas.microsoft.com/powershell/Microsoft.Powershell

这使我直接通过交换服务器上的powershell尝试以下内容

> Get-PSSessionConfiguration | format-list -property name
result:
Name : MyConfigName
Name : microsoft.powershell
Name : microsoft.powershell.workflow
Name : microsoft.powershell32
Name : microsoft.windows.servermanagerworkflows

> $session = New-PSSession -ConfigurationName MyConfigName -ConnectionUri $uri -Authentication Kerberos
result:
error "Cannot find the MyConfigName session configuration in the WSMan: drive on the ComputerName computer."

> $session = New-PSSession -ConfigurationName Microsoft.Powershell -ConnectionUri $uri -Authentication Kerberos
result:
error "Cannot find the Microsoft.Powershell session configuration in the WSMan: drive on the ComputerName."

> $session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri $uri -Authentication Kerberos
result:
nothing, meaning $session variable set correctly

与C＃代码类似，我只能使用Microsoft.Exchange配置，但根据Get-PSSessionConfiguration，此配置不存在，并且该列表中存在的配置将不起作用。

我现在想知道如何使用FullLanguage添加一个配置，我可以在从代码调用powershell时使用它。我可能也完全错了，我的问题根本与PSSessionConfigurations无关，但后来我仍然想知道为什么我无法在任何地方看到Microsoft.Exchange配置。

我最终得到了微软的支持，他们提供了以下解决方案。可以连接到本地PowerShell，然后导入远程会话，而不是通过远程PowerShell会话进行连接。这样做可以解决问题。

错误处理未包含在下面的示例中

var runspace = RunspaceFactory.CreateRunspace();
runspace.Open();

object psSessionConnection;

// Create a powershell session for remote exchange server
using (var powershell = PowerShell.Create())
{
    var command = new PSCommand();
    command.AddCommand("New-PSSession");
    command.AddParameter("ConfigurationName", "Microsoft.Exchange");
    command.AddParameter("ConnectionUri", new Uri(_exchangeConnectionUri));
    command.AddParameter("Authentication", "Kerberos");
    powershell.Commands = command;
    powershell.Runspace = runspace;

    // TODO: Handle errors
    var result = powershell.Invoke();
    psSessionConnection = result[0];
}

// Set ExecutionPolicy on the process to unrestricted
using (var powershell = PowerShell.Create())
{
    var command = new PSCommand();
    command.AddCommand("Set-ExecutionPolicy");
    command.AddParameter("Scope", "Process");
    command.AddParameter("ExecutionPolicy", "Unrestricted");
    powershell.Commands = command;
    powershell.Runspace = runspace;

    powershell.Invoke()
}

// Import remote exchange session into runspace
using (var powershell = PowerShell.Create())
{
    var command = new PSCommand();
    command.AddCommand("Import-PSSession");
    command.AddParameter("Session", psSessionConnection);
    powershell.Commands = command;
    powershell.Runspace = runspace;

    powershell.Invoke();
}
