Penerapan
Contoh
Contoh berikut mengambil pengaktor publik properti dan menampilkan informasi tentang properti tersebut ClassWithProperty.Caption . Ini juga memanggil Invoke metode setter untuk mengatur nilai properti dan getter untuk mengambil nilai properti.
using System;
using System.Reflection;
// Define a property.
public class ClassWithProperty
{
private string _caption = "A Default caption";
public string Caption
{
get { return _caption; }
set { if(_caption != value) _caption = value; }
}
}
class Example
{
public static void Main()
{
ClassWithProperty test = new ClassWithProperty();
Console.WriteLine("The Caption property: {0}", test.Caption);
Console.WriteLine("----------");
// Get the type and PropertyInfo.
Type t = Type.GetType("ClassWithProperty");
PropertyInfo propInfo = t.GetProperty("Caption");
// Get the public GetAccessors method.
MethodInfo[] methInfos = propInfo.GetAccessors();
Console.WriteLine("There are {0} accessors.",
methInfos.Length);
for(int ctr = 0; ctr < methInfos.Length; ctr++) {
MethodInfo m = methInfos[ctr];
Console.WriteLine("Accessor #{0}:", ctr + 1);
Console.WriteLine(" Name: {0}", m.Name);
Console.WriteLine(" Visibility: {0}", GetVisibility(m));
Console.Write(" Property Type: ");
// Determine if this is the property getter or setter.
if (m.ReturnType == typeof(void)) {
Console.WriteLine("Setter");
Console.WriteLine(" Setting the property value.");
// Set the value of the property.
m.Invoke(test, new object[] { "The Modified Caption" } );
}
else {
Console.WriteLine("Getter");
// Get the value of the property.
Console.WriteLine(" Property Value: {0}",
m.Invoke(test, new object[] {} ));

Untuk memanggil GetAccessors metode :
Type Dapatkan objek yang mewakili kelas .
Type Dari objek , dapatkan PropertyInfo objek .
Dari PropertyInfo objek , panggil GetAccessors metode .

Mengembalikan array yang elemennya mencerminkan publik dan, jika ditentukan, non-publik get dan set aksesor properti yang dicerminkan oleh instans saat ini.

- nonPublic
- Boolean
Menunjukkan apakah metode non-publik harus dikembalikan dalam array yang dikembalikan. true jika metode non-publik harus disertakan; jika tidak, false.
Mengembalikan
Array yang elemennya mencerminkan get aksesor dan set properti yang tercermin oleh instans saat ini. Jika nonPublic adalah true, array ini berisi publik dan non-publik get dan set aksesor. Jika nonPublic adalah false, array ini hanya berisi publik get dan set aksesor. Jika tidak ada pengaktif dengan visibilitas yang ditentukan yang ditemukan, metode ini mengembalikan array dengan elemen nol (0).
