Exemples

L’exemple suivant crée un champ, obtient son type et FieldInfo, et affiche son FieldType.

using namespace System;
using namespace System::Reflection;

public ref class TestClass
{
   // Define a field.
   private:
      String^ field = "private field" ;

// public:
//    Myfield()
//       : field( "private field" )
//    {}
// 
// 
//    property String^ Field 
//    {
//       String^ get()
//       {
//          return field;
//       }
// 
//   }
};

void main()
{
   TestClass^ cl = gcnew TestClass;
   
   // Get the type and FieldInfo.
   Type^ t = cl->GetType();
   FieldInfo^ fi = t->GetField("field", 
                   static_cast<BindingFlags>(BindingFlags::Instance | BindingFlags::NonPublic));
   
   // Get and display the Ftype s ieldType.
   Console::WriteLine("Field Name: {0}.{1}", t->FullName, fi->Name );
   Console::WriteLine("Field Value: '{0}'", fi->GetValue(cl));
   Console::WriteLine("Field Type: {0}", fi->FieldType);
}
// The example displays the following output:
//       Field Name: TestClass.field
//       Field Value: 'private field'
//       Field Type: System.String
using System;
using System.Reflection;

public class TestClass
{
    // Define a field.
    private string field = "private field";
}

public class Example
{
    public static void Main()
    {
        var cl= new TestClass();

        // Get the type and FieldInfo.
        Type t = cl.GetType();
        FieldInfo fi = t.GetField("field",
            BindingFlags.Instance | BindingFlags.NonPublic);

        // Get and display the field type.
        Console.WriteLine("Field Name: {0}.{1}", t.FullName, fi.Name);
        Console.WriteLine("Field Value: '{0}'", fi.GetValue(cl));
        Console.WriteLine("Field Type: {0}", fi.FieldType);
    }
}
// The example displays the following output:
//       Field Name: TestClass.field
//       Field Value: 'private field'
//       Field Type: System.String
Imports System.Reflection

Public Class TestClass
    ' Define a field.
    Private field As String = "private field"
End Class

Public Module Example
    Public Sub Main()
        Dim cl As New TestClass()

        ' Get the type and FieldInfo.
        Dim t As Type = cl.GetType()
        Dim fi As FieldInfo = t.GetField("field", _
                 BindingFlags.Instance Or BindingFlags.NonPublic)

        ' Get and display the FieldType.
        Console.WriteLine("Field Name: {0}.{1}", t.FullName, fi.Name)
        Console.WriteLine("Field Value: '{0}'", fi.GetValue(cl))
        Console.WriteLine("Field Type: {0}", fi.FieldType)
    End Sub 
End Module
' The example displays the following output:
'       Field Name: TestClass.field
'       Field Value: 'private field'
'       Field Type: System.String

Remarques

Le type est un type de données primitif, tel que String, Booleanou GUID.

Pour obtenir la FieldType propriété, commencez par obtenir la classe Type. À partir de Type, obtenez le FieldInfo. À partir de FieldInfo, obtenez la FieldType valeur .
