C# 调用PowerShell'；对象来自C的位置#

如何从C#调用

Where Object

（不带过滤器）？我无法解析输出，因为我想将其传递到管道（不在下面的示例中）

附言：

C#：

采集结果=null；
Command command1=新命令（“Get-MailboxPermission”）；
command1.Parameters.Add（“标识”，邮箱）；
command1.Parameters.Add（“DomainController”，_DomainController）；
//我不能使用过滤器。这在PS中也是不可能的。
//command1.Parameters.Add（“过滤器”、“访问权限-匹配\“完全访问\”）；

这个问题类似于：对于我的问题，这个答案是不够的。

检查下面的代码示例。我已经根据您的要求从代码项目中更新了一个示例

注意：

使用

\“

若要将

{

或

}

大括号添加到脚本文本中，请改用双大括号将其转义到字符串中。格式类似于

{

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());
}

Filter

应该是

ScriptBlock

而不是

string

。你知道为什么我总是得到

脚本块文本在受限语言模式或数据段中是不允许的。

exception？你需要在目标机器上运行

Set ExecutionPolicy Unrestricted

。如果你没有使用“Set ExecutionPolicy Unrestricted”的权限？是否仍可以在不使用自定义脚本的情况下使用where object子句？

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\"");

// 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());
}

    //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);
