PropertyInfo.GetGetMethod Metode

Definisi

Ruang nama:

System.Reflection

Rakitan:

System.Runtime.dll

Mengembalikan yang MethodInfo mewakili aksesor get untuk properti ini.

Overload

GetGetMethod(Boolean)	Saat ditimpa di kelas turunan, mengembalikan aksesor publik atau non-publik get untuk properti ini.
GetGetMethod()	Mengembalikan pengaktor publik get untuk properti ini.

GetGetMethod(Boolean)

Sumber:

PropertyInfo.cs

Saat ditimpa di kelas turunan, mengembalikan aksesor publik atau non-publik get untuk properti ini.

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

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

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

Public MustOverride Function GetGetMethod (nonPublic As Boolean) As MethodInfo

Parameter

nonPublic

Boolean

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

Mengembalikan

MethodInfo

Objek MethodInfo yang mewakili pengaktor get untuk properti ini, jika nonPublic adalah true. Mengembalikan null jika nonPublic adalah false dan get aksesor non-publik, atau jika nonPublic tidak ada true tetapi tidak get ada pengaktor.

Pengecualian

SecurityException

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

Contoh

Contoh berikut menampilkan aksesor publik atau non-publik get untuk properti yang ditentukan.

Keterangan

Properti ini adalah MethodInfo yang mewakili get accessor.

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

GetGetMethod()

Sumber:

PropertyInfo.cs

Mengembalikan pengaktor publik get untuk properti ini.

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

public System.Reflection.MethodInfo? GetGetMethod ();

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

Public Function GetGetMethod () As MethodInfo

Mengembalikan

MethodInfo

Objek MethodInfo yang mewakili aksesor publik get untuk properti ini, atau null jika get aksesor non-publik atau tidak ada.

Keterangan

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

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