Примеры

В следующем примере создается поле, получается его тип и FieldInfoи отображается его FieldType.The following example creates a field, gets its type and FieldInfo, and displays its 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

Комментарии

Тип является некоторым примитивным типом данных, например String, Booleanили GUID.The type is some primitive data type, such as String, Boolean, or GUID.

Чтобы получить свойство FieldType, сначала получите класс Type.To get the FieldType property, first get the class Type. В Typeполучите FieldInfo.From the Type, get the FieldInfo. В FieldInfoполучите значение FieldType.From the FieldInfo, get the FieldType value.
