c# - 从 C# 调用 PowerShell 的 where-object

Question

如何从 C# 调用 Where-Object(不带过滤器)？我无法解析输出，因为我想将它传递给管道(不在下面的示例中)。

附言:

Get-MailboxPermission username | Where-Object {$_.AccessRights -match "FullAccess" -and $_.IsInherited -eq $False}

C#:

Collection<PSObject> results = null;

Command command1 = new Command("Get-MailboxPermission");
command1.Parameters.Add("Identity", mailbox);
command1.Parameters.Add("DomainController", _domainController);
//I cannot use Filter. This is not possible in PS also.
//command1.Parameters.Add("Filter", "AccessRights -match \"FullAccess\"");

这个问题类似于:PowerShell WhereObjectCommand from C#这个答案不足以解决我的问题。

Answer 1

检查下面的代码示例。我已经更新了代码项目中的示例 here根据您的要求。

注意:

1. 为您的命令添加引号，即使用 \"
脚本文本转义引号

2. 要将 { 或 } 大括号添加到脚本文本中，请使用双大括号将其转义到 String.Format 中，例如 {{ 或 }}

   // create Powershell runspace
   Runspace runspace = RunspaceFactory.CreateRunspace();
   
   // open it
   runspace.Open();
   
   // create a pipeline and feed it the script text
   Pipeline pipeline = runspace.CreatePipeline();
   
   //Getting all command variables
   string computerName = "YourComputerName";
   string matchingPattern = "con";
   
   //Create Script command
   String customScriptText = String.Format("Get-Process -ComputerName {0} | Where-Object {{$_.ProcessName -match \"{1}\"}}", computerName,matchingPattern);
   
   pipeline.Commands.AddScript(customScriptText);
   
   // add an extra command to transform the script output objects into nicely formatted strings
   // remove this line to get the actual objects that the script returns.
   pipeline.Commands.Add("Out-String");
   
   // execute the script
   Collection<PSObject> results = pipeline.Invoke();
   
   // close the runspace
   runspace.Close();
   
   // convert the script result into a single string
   StringBuilder stringBuilder = new StringBuilder();
   foreach (PSObject obj in results)
   {
       stringBuilder.AppendLine(obj.ToString());
   }
   

当您将上述工作示例应用到您的问题时，您需要更改如下几行:

    //Getting all command variables
    string username = "YourUserName";

    //Create Script command
    String customScriptText = String.Format("Get-MailboxPermission {0} | Where-Object {{$_.AccessRights -match \"FullAccess\" -and $_.IsInherited -eq $False}}", username);
