BuildProvider.CodeCompilerType Properti

Definisi

Ruang nama:

System.Web.Compilation

Rakitan:

System.Web.dll

Mewakili jenis pengkompilasi yang digunakan oleh penyedia build untuk menghasilkan kode sumber untuk jenis file kustom.

public:
 virtual property System::Web::Compilation::CompilerType ^ CodeCompilerType { System::Web::Compilation::CompilerType ^ get(); };

public virtual System.Web.Compilation.CompilerType CodeCompilerType { get; }

member this.CodeCompilerType : System.Web.Compilation.CompilerType

Public Overridable ReadOnly Property CodeCompilerType As CompilerType

Nilai Properti

CompilerType

Baca-saja CompilerType yang mewakili generator kode, pengkompilasi kode, dan pengaturan kompilator yang digunakan untuk membangun kode sumber untuk jalur virtual. Kelas dasar mengembalikan null.

Keterangan

CodeCompilerType Gunakan properti untuk menyediakan pengaturan untuk mengkompilasi kode sumber untuk implementasi BuildProvider. Properti CodeCompilerType ini adalah null jika penyedia build tidak memerlukan bahasa kode tertentu untuk menghasilkan dan mengkompilasi kode sumber.

Untuk mengatur nilai untuk CompilerType objek dalam implementasi penyedia build, gunakan GetDefaultCompilerType metode atau GetDefaultCompilerTypeForLanguage .

Properti CodeDomProviderType menentukan CodeDomProvider implementasi yang digunakan untuk menghasilkan dan mengkompilasi kode sumber untuk penyedia build. Properti CompilerParameters menentukan pengaturan yang digunakan untuk mengkompilasi kode sumber ke dalam rakitan.
