PropertyInfo.GetSetMethod Metode

Definisi

Ruang nama:

System.Reflection

Rakitan:

System.Runtime.dll

Mengembalikan yang MethodInfo mewakili aksesor set untuk properti ini.

Overload

GetSetMethod(Boolean)	Saat ditimpa di kelas turunan, mengembalikan aksesor set untuk properti ini.
GetSetMethod()	Mengembalikan pengaktor publik set untuk properti ini.

GetSetMethod(Boolean)

Sumber:

PropertyInfo.cs

Saat ditimpa di kelas turunan, mengembalikan aksesor set untuk properti ini.

public:
 abstract System::Reflection::MethodInfo ^ GetSetMethod(bool nonPublic);

public abstract System.Reflection.MethodInfo? GetSetMethod (bool nonPublic);

abstract member GetSetMethod : bool -> System.Reflection.MethodInfo

Public MustOverride Function GetSetMethod (nonPublic As Boolean) As MethodInfo

Parameter

nonPublic

Boolean

Menunjukkan apakah aksesor harus dikembalikan jika non-publik. true jika aksesor non-publik akan dikembalikan; jika tidak, false.

Mengembalikan

MethodInfo

Metode properti Set ini, atau null, seperti yang ditunjukkan dalam tabel berikut.

Nilai	Kondisi
Metode Set untuk properti ini.	Aksesor set bersifat publik, OR nonPublic adalah true dan set aksesornya non-publik.
null	nonPublic adalah true, tetapi properti bersifat baca-saja, ATAU nonPublic adalah false dan set aksesor non-publik, ATAU tidak set ada pengaktor.

Pengecualian

SecurityException

Metode yang diminta bersifat non-publik dan pemanggil tidak harus ReflectionPermission merefleksikan metode non-publik ini.

Contoh

Contoh berikut menampilkan pengaktor set untuk properti yang ditentukan.

Keterangan

Untuk menggunakan metode ini, pertama-tama GetSetMethod dapatkan kelas Type. TypeDari , dapatkan PropertyInfo. PropertyInfoDari , gunakan GetSetMethod metode .

GetSetMethod()

Sumber:

PropertyInfo.cs

Mengembalikan pengaktor publik set untuk properti ini.

public:
 System::Reflection::MethodInfo ^ GetSetMethod();

public System.Reflection.MethodInfo? GetSetMethod ();

member this.GetSetMethod : unit -> System.Reflection.MethodInfo

Public Function GetSetMethod () As MethodInfo

Mengembalikan

MethodInfo

Objek MethodInfo yang Set mewakili metode untuk properti ini jika aksesor set adalah publik, atau null jika pengaktor set tidak publik.

Keterangan

Ini adalah metode kenyamanan yang menyediakan implementasi untuk metode abstrak GetSetMethod dengan parameter yang nonPublic diatur ke false.

Untuk menggunakan metode ini, pertama-tama GetSetMethod dapatkan kelas Type. TypeDari , dapatkan PropertyInfo. PropertyInfoDari , gunakan GetSetMethod metode .
