Question

I created a powershell object via .net to invoke commands. When I invoke normal commands like Get-Process I had no problems:

ps.AddCommand("Get-Process").AddParameter(...).Invoke()

但是,我无法以“名称:方法”为代号,仅举一个援引[System.IO.File]的例子:Exists(“c:oo.txt”)。

我在审判中

ps.AddCommand("[System.IO.File]::Exists("c:\boo.txt")").Invoke()

ps.AddCommand("[System.IO.File]::Exists").AddArgument("c:\boo.txt").Invoke()

and some others. It always throws an exception which says that the command specified is not recognized.

There is a way to invoke that type of command? Thanks

自发出呼吁以来,你需要在管道上添加<条码>。 NET需要文字。 NET方法不被视为PowerShell commands。 e.g:

static void Main()
{
     PowerShell ps = PowerShell.Create();
     ps.AddScript(@"[IO.File]::Exists( C:UsersKeithfoo.txt )");
     foreach (PSObject result in ps.Invoke())
     {
         Console.WriteLine(result);
     }
}
