PowerShell ParameterBindingException
我目前正在构建一个应用程序，以从ASP.NET MVC网站自动执行某些Exchange 2010操作。
现在，当我尝试调用New-AddressList命令时，我遇到了一个ParameterBindingException。
我正在尝试创建以下调用（有效）：
new-AddressList -Name "7 AL" -RecipientContainer "myDomain.local/Customers/7" -IncludedRecipients 'AllRecipients' -Container '\' -DisplayName "7 AL" 我是通过以下方式做到的：
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);
此命令列表提供给我调用的管道，给出以下错误：
New-AddressList：输入对象不能绑定到命令的任何参数，因为该命令不接受管道输入或输入及其属性与接受管道输入的任何参数都不匹配。
- CategoryInfo：InvalidArgument：（7：PSObject）[New-AddressList]，ParameterBindingException
- FullyQualifiedErrorId：InputObjectNotBound，Microsoft.Exchange.Management.SystemConfigurationTasks.NewAddressList
任何可能导致这种情况的线索？
使用Trace-Command输出给出：

我发现必须单独调用每个命令，因为它们不相关。 问题产生于我对Powershell管道概念的误解。
为什么要将命令声明为var ？ 我的意思是：
命令NewAddressList = new命令（“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，为什么不直接使用Powershell类？
编辑：追踪后进一步猜测
您正在使用的重载版本的Parameters.Add将键（字符串）和值（对象）作为参数。 可能c＃不会做同样出色的工作：/。 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 。
尝试演员。
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”）;
