如何使用c#中的“format-list”和“out-file”管道调用powershell命令?

嗨,我正在开发一个C#程序来调用远程运行空间中的Exchange 2010 powershell cmdlet。 ps命令是:

“Get-MailboxDatabase -Server EX2010SVR1 -Status | Format-List Identity,Guid,mounted,CircularLoggingEnabled,Recovery | Out-File’C:\ db.txt’-Encoding UTF8 -Width 8192”。

我的代码类似于:

static int Main(string[] args) { const string SHELL_URI = "http://schemas.microsoft.com/powershell/Microsoft.Exchange"; const string COMMAND = "Get-MailboxDatabase -Server EX2010SVR1 -Status | Format-List Identity,Guid,mounted,CircularLoggingEnabled,Recovery | Out-File 'C:\db.txt' -Encoding UTF8 -Width 8192"; System.Uri serverUri = new Uri("http://EX2010SVR1/powershell?serializationLevel=Full"); PSCredential creds = (PSCredential)null; // Use Windows Authentication WSManConnectionInfo connectionInfo = new WSManConnectionInfo(serverUri, SHELL_URI, creds); try { using (Runspace rs = RunspaceFactory.CreateRunspace(connectionInfo)) { rs.Open(); PowerShell psh = PowerShell.Create(); psh.Runspace = rs; psh.AddCommand(COMMAND); Collection results = psh.Invoke(); rs.Close(); } } catch (Exception ex) { System.Console.WriteLine("exception: {0}", ex.ToString()); } return 0; } 

当我在托管Exchange 2010服务器的Win2008 R2上运行c#程序时,我总是得到例外:

 System.Management.Automation.RemoteException: The term 'Format-List' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again. at System.Management.Automation.PowerShell.CoreInvoke[TOutput](IEnumerable input, PSDataCollection`1 output, PSInvocationSettings settings) at System.Management.Automation.PowerShell.Invoke(IEnumerable input, PSInvocationSettings settings) at System.Management.Automation.PowerShell.Invoke() at RemotePS.Program.Main(String[] args) 

没有“Format-List”和“Out-File”管道,程序运行正常。 整个命令在Exchange 2010管理shell中也运行良好。 我还确认它是系统上的powershell 2.0。

任何人都可以帮助弄清楚发生了什么吗? 任何帮助深表感谢。

我写的第一个嵌入式PowerShell遇到了同样的问题。 我寻找痕迹,但我再也找不到了。

以下是适合我的代码:

 static void Main(string[] args) { const string SHELL_URI = "http://schemas.microsoft.com/powershell/Microsoft.PowerShell"; const string COMMAND = @"get-process | format-List | Out-File -file c:\temp\jpb.txt"; System.Uri serverUri = new Uri("http://WM2008R2ENT/powershell?serializationLevel=Full"); PSCredential creds = (PSCredential)null; // Use Windows Authentication WSManConnectionInfo connectionInfo = new WSManConnectionInfo(false, "WM2008R2ENT", 5985, "/wsman", SHELL_URI, creds); try { using (Runspace rs = RunspaceFactory.CreateRunspace(connectionInfo)) { rs.Open(); Pipeline pipeline = rs.CreatePipeline(); string cmdLine; cmdLine = string.Format("&{{{0}}}", COMMAND); pipeline.Commands.AddScript(cmdLine); Collection results = pipeline.Invoke(); rs.Close(); } } catch (Exception ex) { System.Console.WriteLine("exception: {0}", ex.ToString()); } return; } 

小心,我没有使用Exchange PowerShell

在我使用管道的示例中,您的问题可能来自您传递命令的方式。

您可以尝试使用’Command’-Object。

 Runspace rs = RunspaceFactory.CreateRunspace(); PowerShell ps = PowerShell.Create(); Pipeline pipeline = rs.CreatePipeline(); Command cmd1 = new Command("Get-MailboxDatabase"); cmd1.Parameters.Add("Server", "EX2010SVR1"); cmd1.Parameters.Add("Status"); pipeline.Commands.Add(cmd1); Command cmd2 = new Command("Format-List"); cmd2.Parameters.Add("Property", "Identity, Guid, mounted, CircularLoggingEnabled, Recovery"); pipeline.Commands.Add(cmd2); Command cmd3 = new Command("Format-List"); cmd3.Parameters.Add("FilePath", "C:\db.txt"); cmd3.Parameters.Add("Encoding", "UTF8"); cmd3.Parameters.Add("Width", "8192"); pipeline.Commands.Add(cmd3); Collection output = pipeline.Invoke();

我意识到这是一个老问题,但我想提出我的发现,不管它们是多么短暂。

最近我和我的一位同事遇到了同样的问题。 我们设法将问题跟踪到缺少的运行空间。 我们还必须连接到Microsoft.Exchange空间,当我们这样做时, Format-List命令行开关变得不可用。 如果我们不使用运行空间,那么命令行开关就可以了。

我们还没有解决它,但我打算探索使用RunspacePool而不仅仅是Runspace的可能性,从而允许在管道中执行两个命令行开关。
