Powershell関係と徒然なこと

PowerShell Action delegate

PowerShell Action delegate

Action/Funcはdelegate

  • Action : 戻り値なし、引数なし。
  • Action: 戻り値なし、引数1
  • Func<T,TResult: 戻り値1,引数1

PowerShellでは

  • [action]
  • [action[int]]
  • [func[int][int]] ?
  • or func[int,int]] ?

Funcの例

Func<T,TResult>

using System;

public class GenericFunc
{
   public static void Main()
   {
      // Instantiate delegate to reference UppercaseString method
      Func<string, string> convertMethod = UppercaseString;
      string name = "Dakota";
      // Use delegate instance to call UppercaseString method
      Console.WriteLine(convertMethod(name));
   }

   private static string UppercaseString(string inputString)
   {
      return inputString.ToUpper();
   }
}
