Contoh

Contoh berikut menunjukkan cara membuat dan menggunakan properti cakupan aplikasi menggunakan Properties.

Keterangan

Application mengekspos kamus melalui Properties yang dapat Anda gunakan untuk menyimpan properti cakupan aplikasi. Ini memungkinkan Anda untuk berbagi status di antara semua kode dengan cara yang AppDomain aman utas, tanpa perlu menulis kode status Anda sendiri.

Properti yang disimpan di harus dikonversi Properties ke jenis yang sesuai yang dikembalikan.

Properti Properties ini aman untuk utas dan tersedia dari utas apa pun.
