PowerShell ParameterBindingException
我目前正在构建一个应用程序，以便从ASP.NET MVC网站自动执行一些Exchange 2010操作。
现在，当我尝试调用New-AddressList命令时，我遇到了ParameterBindingException。
我正在尝试创建以下调用（其工作原理）：
new-AddressList -Name "7 AL" -RecipientContainer "myDomain.local/Customers/7" -IncludedRecipients 'AllRecipients' -Container '' -DisplayName "7 AL"
我是这样做的：
var NewAddressList = new Command("New-AddressList");
NewAddressList.Parameters.Add("Name", "7 AL");
NewAddressList.Parameters.Add("RecipientContainer", "myDomain.local/Customers/7");
NewAddressList.Parameters.Add("IncludedRecipients", "AllRecipients");
NewAddressList.Parameters.Add("Container", @"");
NewAddressList.Parameters.Add("DisplayName", "7 AL");
CommandsList.Add(NewAddressList);
该命令列表提供给我调用的管道，给我以下错误：
New-AddressList：输入对象不能绑定到该命令的任何参数，因为该命令不需要管道输入，或者输入及其属性不匹配任何采用流水线输入的参数。
任何可能导致这种情况的线索？
用Trace-Command输出给出：

我发现每个命令都必须单独调用，因为它们不相关。 这个问题源于我对Powershell管道概念的误解。
你为什么要将命令声明为var ？ 我的意思是：
Command NewAddressList = new Command("New-AddressList");
然后，尝试添加命令作为CommandParameter对象（如此处所示）：
CommandParameter NameParam = new CommandParameter("Name","7 AL");
NewAddressList.Parameters.Add(NameParam);
最后，为什么你不直接使用Powershell类？
编辑：跟踪后的进一步猜测
Parameters.Add的重载版本使用的Parameters.Add是一个键（字符串）和一个值（对象）。 可能c＃没有做同样的好工作powershell不会：/。 尝试将值作为所需类型的对象传递。 例如， included-recipient参数需要Microsoft.Exchange.Data.Directory.Recipient.WellKnownRecipientType 。
尝试施放。
例：
Microsoft.Exchange.Data.Directory.Recipient.WellKnownRecipientType allrecips = (Microsoft.Exchange.Data.Directory.Recipient.WellKnownRecipientType) "AllRecipients";
NewAddressList.Parameters.Add("IncludedRecipients", allrecips);
或者（我知道这可能很愚蠢）：
NewAddressList.Parameters.Add("IncludedRecipients", "[Microsoft.Exchange.Data.Directory.Recipient.WellKnownRecipientType] AllRecipients");
