vb.netのパラメータを持つpowershellスクリプトを実行しています

Question

vb.netコードで蹴りたいPowerShellスクリプトがありますが、パイプラインを呼び出す部分に到達するとエラーが発生します。「コマンドを処理できません。 1つまたは複数の欠落している必須パラメータのうち、地区郡FMS。 powershellスクリプトは非常に単純ですが、3つのパラメータとwrite-hostのパラメータ値をシェルに返します。かなり私の質問は、私はそれを動作させる方法ですか？みなさん、ありがとうございました。

これらの例は、C＃であるが、それは同じAPIです。

よりC＃の例が、これらは、すでにあなたのパイプラインを持っているRunspaceFactory APIを使用しています。 Execute PowerShell Script from C# with Commandline Arguments
