ParameterInfo.Name Eigenschap

public:
 virtual property System::String ^ Name { System::String ^ get(); };

public virtual string Name { get; }

public virtual string? Name { get; }

member this.Name : string

Public Overridable ReadOnly Property Name As String

Waarde van eigenschap

De eenvoudige naam van deze parameter.

Voorbeelden

In het volgende voorbeeld ziet u hoe u objecten ophaalt ParameterInfo voor de parameters van een methode en vervolgens de Name eigenschap gebruikt om de parameternamen op te halen.

using System;
using System.Reflection;

class parminfo
{
    public static void mymethod (
       int int1m, out string str2m, ref string str3m)
    {
       str2m = "in mymethod";
    }

    public static int Main(string[] args)
    {
       Console.WriteLine("\nReflection.Parameterinfo");

       //Get the ParameterInfo parameter of a function.

       //Get the type.
       Type Mytype = Type.GetType("parminfo");

       //Get and display the method.
       MethodBase Mymethodbase = Mytype.GetMethod("mymethod");
       Console.Write("\nMymethodbase = " + Mymethodbase);

       //Get the ParameterInfo array.
       ParameterInfo[] Myarray = Mymethodbase.GetParameters();

       //Get and display the name of each parameter.
       foreach (ParameterInfo Myparam in Myarray)
       {
          Console.Write ("\nFor parameter # "   + Myparam.Position
             + ", the Name is - " +  Myparam.Name);
       }
       return 0;
    }
 }

Opmerkingen

Deze eigenschap maakt gebruik van het beveiligde NameImpl veld en is afhankelijk van een optionele metagegevensvlag die mogelijk niet beschikbaar is in alle compilers.

Als u de ParameterInfo matrix wilt ophalen, moet u eerst de methode of de constructor ophalen en vervolgens de MethodBase.GetParameters methode aanroepen.
