ParameterInfo.Attributes Özellik

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

Özellik Değeri

ParameterAttributes Bu parametrenin özniteliklerini temsil eden bir nesne.

Örnekler

Aşağıdaki örnek, üç parametreli bir yöntemi tanımlar. İkinci parametrenin özniteliklerini almak ve konsolda görüntülemek için özelliğini kullanır Attributes .

using namespace System;
using namespace System::Reflection;
using namespace System::Runtime::InteropServices;
public ref class MyClass1
{
public:
   int MyMethod( int i, [Out]short * j, long * k )
   {
       *j = 2;
      return 0;
   }

};

void main()
{
   // Get the type. 
   Type^ myType = MyClass1::typeid;

   // Get the method named 'MyMethod' from the type.
   MethodBase^ myMethodBase = myType->GetMethod( "MyMethod" );

   // Get the parameters associated with the method.
   array<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 );
}

using System;

   public int MyMethod( int i, out short j, ref long k)

      // 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);
   }
}
