Bagian kode yang menyebabkan pengecualian.

Contoh

Contoh Formulir Web berikut memanggil Math metode layanan Web XML, yang melemparkan pengecualian jika pembagian dengan nol terjadi. Ketika pengecualian dilemparkan, Formulir Web menangkap pengecualian dan menghasilkan detail pengecualian, termasuk Actor properti dan Code , ke dalam HtmlTable kontrol.

Keterangan

Properti Actor hanya dapat diatur menggunakan salah satu konstruktor yang menerima Actor argumen.

Ketika permintaan SOAP dibuat, pesan dikirim ke penerima, yang ditentukan dalam atribut aktor SOAP. Jika pengecualian terjadi dalam layanan Web XML, nilai atribut aktor SOAP ditetapkan ke Actor properti . Untuk layanan Web XML yang dibuat menggunakan ASP.NET, URL ke metode layanan Web XML adalah nilai atribut aktor SOAP dan dikembalikan dalam Actor properti .

Untuk informasi selengkapnya tentang atribut aktor SOAP, lihat spesifikasi SOAP .
