Powershell 多个 AddParameter C# [英] Powershell multiple AddParameter C#

问题描述

我从 C# 表单应用程序中运行 PowerShell.我想向我的 PowerShell 命令添加多个参数.

I run a PowerShell from within a C# form application. I want to add multiple parameters to my PowerShell command.

但是当我输入第二个 AddParameter 调用时，它失败并显示错误:

But when I enter a second AddParameter call, it failed with the error:

System.Management.Automation.ParameterBindingException

System.Management.Automation.ParameterBindingException

代码:

PowerShell shell = PowerShell.Create().AddCommand("Get-NetAdapter");
shell.AddParameter("name", "Ethernet*");
shell.AddParameter("InterfaceIndex", "5");

foreach (PSObject result in shell.Invoke())
{
    Console.WriteLine("{0,-24}{1}", result.Members["Name"].Value,
                                    result.Members["InterfaceDescription"].Value);
} // End foreach.

看起来它只接受 1 个参数.

It looks like it only accepts 1 parameter.

还有一个 AddParameters，但我无法使其正常工作.

There is also a AddParameters, but I'm not able to get this working.

有人有这方面的经验吗?

Anyone got any experience with this?

推荐答案

实际上不能将 name 和 InterfaceIndex 与 Get 同时使用-NetAdapter cmdlet.这是因为它们属于不同的参数集，因此必须单独使用.

You can't actually use name and InterfaceIndex at the same time with the Get-NetAdapter cmdlet. This is because they belong to different Parameter Sets and as a result must be used separately.

要查看该 cmdlet 的参数集的详细信息，请参见此处:https://technet.microsoft.com/en-us/library/jj130867(v=wps.630).aspx

或者在 PowerShell 中使用 Get-Help Get-NetAdapter.

Or use Get-Help Get-NetAdapter in PowerShell.

但是，如果您在使用同一参数集中允许的参数添加参数时仍然遇到问题，您可以尝试将两个参数添加为单个命令，如下所示(使用 name 和 throttlelimit 为例，因为它们在同一参数集中被允许:ByName for Get-NetAdapter):

However if you are still having issues adding parameters when using ones that are permitted in the same parameter set, you could try adding both parameters as a single command, like this (using name and throttlelimit as an example, as they are permitted in the same Parameter Set: ByName for Get-NetAdapter):

PowerShell shell = PowerShell.Create().AddCommand("Get-NetAdapter")
                                      .AddParameter("name", "Ethernet*")
                                      .AddParameter("ThrottleLimit", 5);

或者，您也可以使用参数名称和值的字典:

Or alternatively you can use a dictionary of parameter names and values:

IDictionary parameters = new Dictionary<String, String>();
parameters.Add("name", "Ethernet*");
parameters.Add("ThrottleLimit", 5);

PowerShell shell = PowerShell.Create().AddCommand("Get-NetAdapter")
   .AddParameters(parameters)
