Keterangan
StackTrace informasi akan paling informatif dengan konfigurasi build Debug. Secara default, build Debug menyertakan simbol debug, sementara Build rilis tidak. Simbol debug berisi sebagian besar file, nama metode, nomor baris, dan informasi kolom yang digunakan dalam membangun objek StackFrame dan StackTrace.
StackTrace mungkin tidak melaporkan panggilan metode sebanyak yang diharapkan, karena transformasi kode yang terjadi selama pengoptimalan.
Konstruktor
StackTrace() |
Menginisialisasi instans baru kelas StackTrace dari bingkai pemanggil. |
StackTrace(Boolean) |
Menginisialisasi instans baru kelas StackTrace dari bingkai pemanggil, secara opsional menangkap informasi sumber. |
StackTrace(Exception, Boolean) |
Menginisialisasi instans baru kelas StackTrace, menggunakan objek pengecualian yang disediakan dan secara opsional menangkap informasi sumber. |
StackTrace(Exception, Int32, Boolean) |
Menginisialisasi instans baru kelas StackTrace menggunakan objek pengecualian yang disediakan, melewati jumlah bingkai yang ditentukan dan mengambil informasi sumber secara opsional. |
StackTrace(Exception, Int32) |
Menginisialisasi instans baru kelas StackTrace menggunakan objek pengecualian yang disediakan dan melewati jumlah bingkai yang ditentukan. |
StackTrace(Exception) |
Menginisialisasi instans baru kelas StackTrace menggunakan objek pengecualian yang disediakan. |
StackTrace(IEnumerable<StackFrame>) |
Membuat jejak tumpukan dari sekumpulan objek StackFrame. |
StackTrace(Int32, Boolean) |
Menginisialisasi instans baru kelas StackTrace dari bingkai pemanggil, melewati jumlah bingkai yang ditentukan dan secara opsional menangkap informasi sumber. |
