ParameterInfo.Attributes Eigenschaft

public:
 virtual property System::Reflection::ParameterAttributes Attributes { System::Reflection::ParameterAttributes get(); };

public virtual System.Reflection.ParameterAttributes Attributes { get; }

member this.Attributes : System.Reflection.ParameterAttributes

Public Overridable ReadOnly Property Attributes As ParameterAttributes

Eigenschaftswert

Ein ParameterAttributes Objekt, das die Attribute für diesen Parameter darstellt.

Beispiele

Im folgenden Beispiel wird eine Methode mit drei Parametern definiert. Sie verwendet die Attributes Eigenschaft, um die Attribute der einzelnen Parameter abzurufen und in der Konsole anzuzeigen.

using System;
using System.Reflection;
public class MyClass1
{
   public int MyMethod( int i, out short j, ref long k)
   {
      j = 2;
      return 0;
   }
}

public class ParameterInfo_Attributes
{
   public static void Main()
   {
      // Get the type.
      Type myType = typeof(MyClass1);
      // Get the method named 'MyMethod' from the type.
      MethodBase myMethodBase = myType.GetMethod("MyMethod");
      // Get the parameters associated with the method.
      ParameterInfo[] myParameters = myMethodBase.GetParameters();
      Console.WriteLine("\nThe method {0} has the {1} parameters :",
                          "ParameterInfo_Example.MyMethod", myParameters.Length);
      // Print the attributes associated with each of the parameters.
      for(int i = 0; i < myParameters.Length; i++)
         Console.WriteLine("\tThe {0} parameter has the attribute : {1}",
                                             i + 1, myParameters[i].Attributes);
   }
}

Imports System.Reflection

Public Class MyClass1
   
   Public Function MyMethod(i As Integer, ByRef j As Short, ByRef k As Long) As Integer
      j = 2
      Return 0
   End Function 'MyMethod
End Class

Public Class ParameterInfo_Attributes
   
   Public Shared Sub Main()
      ' Get the type. 
      Dim myType As Type = GetType(MyClass1)
      ' Get the method named 'MyMethod' from the type.
      Dim myMethodBase As MethodBase = myType.GetMethod("MyMethod")
      ' Get the parameters associated with the method.
      Dim myParameters As ParameterInfo() = myMethodBase.GetParameters()
      Console.WriteLine(ControlChars.Cr + "The method {0} has the {1} parameters :", "ParameterInfo_Example.MyMethod", myParameters.Length)
      ' Print the attributes associated with each of the parameters.
      Dim i As Integer
      For i = 0 To myParameters.Length - 1
         Console.WriteLine(ControlChars.Tab + "The {0} parameter has the attribute : {1}", i + 1, myParameters(i).Attributes)
      Next i
   End Sub
End Class

Hinweise

Diese Methode verwendet die AttrsImpl Methode.

Rufen Sie zum Abrufen des ParameterInfo Arrays zuerst die Methode oder den Konstruktor ab, und rufen Sie dann auf MethodBase.GetParameters.
