AppDomain.ReflectionOnlyGetAssemblies Metode

Definisi

Ruang nama:

System

Rakitan:

netstandard.dll, System.Runtime.dll

Sumber:

AppDomain.cs

Mengembalikan rakitan yang telah dimuat ke dalam konteks hanya refleksi domain aplikasi.

public:
 cli::array <System::Reflection::Assembly ^> ^ ReflectionOnlyGetAssemblies();

public System.Reflection.Assembly[] ReflectionOnlyGetAssemblies();

member this.ReflectionOnlyGetAssemblies : unit -> System.Reflection.Assembly[]

Public Function ReflectionOnlyGetAssemblies () As Assembly()

Mengembalikan

Assembly[]

Array Assembly objek yang mewakili rakitan yang dimuat ke dalam konteks hanya refleksi domain aplikasi.

Pengecualian

AppDomainUnloadedException

Operasi dicoba pada domain aplikasi yang tidak dimuat.

Contoh

Contoh kode berikut memuat rakitan System.dll ke dalam konteks eksekusi lalu ke dalam konteks khusus pantulan. Metode GetAssemblies dan ReflectionOnlyGetAssemblies digunakan untuk menampilkan rakitan yang dimuat ke dalam setiap konteks.

   // Load System.dll into the reflection-only context. Note that 
   // if you obtain the display name (for example, by running this
