Ejemplos

En el ejemplo siguiente se define una clase Employee que tiene cinco propiedades.The following example defines an Employee class that has five properties. A continuación, usa recupera una matriz de PropertyInfo objetos que representan esas propiedades y muestra el nombre y el tipo de cada uno.It then uses retrieves an array of PropertyInfo objects that represent those properties and displays the name and type of each.

using System;
using System.Reflection;

public class Employee
{
   private string _id;

   public String FirstName { get; set; }
   public String MiddleName { get; set; }
   public String LastName  { get; set; }
   public DateTime HireDate  { get; set; }

   public String ID
   {
      get { return _id; }
      set {
         if (ID.Trim().Length != 9)
            throw new ArgumentException("The ID is invalid");
         _id = value;
      }
   }
}

public class Example
{
   public static void Main()
   {
      Type t = typeof(Employee);
      Console.WriteLine("The {0} type has the following properties: ",
                        t.Name);
      foreach (var prop in t.GetProperties())
         Console.WriteLine("   {0} ({1})", prop.Name,
                           prop.PropertyType.Name);
   }
}
// The example displays the following output:
//       The Employee type has the following properties:
//          FirstName (String)
//          MiddleName (String)
//          LastName (String)

Comentarios

Para determinar el tipo de una propiedad determinada, haga lo siguiente:To determine the type of a particular property, do the following:

  1. Obtiene un objeto Type que representa el tipo (la clase o estructura) que contiene la propiedad.Get a Type object that represents the type (the class or structure) that contains the property. Si está trabajando con un objeto (una instancia de un tipo), puede llamar a su método GetType.If you are working with an object (an instance of a type), you can call its GetType method. De lo contrario, puede usar C# el operador o el operador Visual Basic GetType , como se muestra en el ejemplo.Otherwise, you can use the C# operator or the Visual Basic GetType operator, as the example illustrates.

  2. Obtiene un objeto PropertyInfo que representa la propiedad en la que está interesado.Get a PropertyInfo object that represents the property in which you're interested. Para ello, puede obtener una matriz de todas las propiedades del método Type.GetProperties y, a continuación, recorrer en iteración los elementos de la matriz, o bien puede recuperar el PropertyInfo objeto que representa la propiedad directamente llamando al método Type.GetProperty y especificando el nombre de la propiedad.You can do this by getting an array of all properties from the Type.GetProperties method and then iterating the elements in the array, or you can retrieve the PropertyInfo object that represents the property directly by calling the Type.GetProperty method and specifying the property name.

  3. Recupere el valor de la propiedad PropertyType del objeto PropertyInfo.Retrieve the value of the PropertyType property from the PropertyInfo object.
