Keterangan

Dalam file konfigurasi, bagian konfigurasi berisi atribut dan elemen. Koleksi ConfigurationLockCollection ada untuk atribut terkunci dari bagian konfigurasi, dan diakses melalui LockAttributes properti ConfigurationElement kelas . Koleksi lain ConfigurationLockCollection ada untuk elemen terkunci dari bagian konfigurasi, dan diakses melalui LockElements properti ConfigurationElement kelas .

Properti

AttributeList	Mendapatkan daftar objek konfigurasi yang terkandung dalam koleksi.
Count	Mendapatkan jumlah objek konfigurasi terkunci yang terkandung dalam koleksi.
HasParentElements	Mendapatkan nilai yang menentukan apakah kumpulan objek terkunci memiliki elemen induk.
IsModified	Mendapatkan nilai yang menentukan apakah koleksi telah dimodifikasi.
IsSynchronized	Mendapatkan nilai yang menentukan apakah koleksi disinkronkan.
SyncRoot	Mendapatkan objek yang digunakan untuk menyinkronkan akses ke koleksi ini ConfigurationLockCollection .

Metode

Add(String)	Mengunci objek konfigurasi dengan menambahkannya ke koleksi.
Clear()	Menghapus semua objek konfigurasi dari koleksi.
Contains(String)	Memverifikasi apakah objek konfigurasi tertentu terkunci.
CopyTo(String[], Int32)	Menyalin seluruh ConfigurationLockCollection koleksi ke satu dimensi Arrayyang kompatibel, dimulai pada indeks array target yang ditentukan.
Equals(Object)	Menentukan apakah objek yang ditentukan sama dengan objek saat ini. (Diperoleh dari Object)
GetEnumerator()	IEnumerator Mendapatkan objek, yang digunakan untuk melakukan iterasi melalui koleksi iniConfigurationLockCollection.
GetHashCode()	Berfungsi sebagai fungsi hash default. (Diperoleh dari Object)
GetType()	Mendapatkan instans Type saat ini. (Diperoleh dari Object)
IsReadOnly(String)	Memverifikasi apakah objek konfigurasi tertentu bersifat baca-saja.
MemberwiseClone()	Membuat salinan dangkal dari yang saat ini Object. (Diperoleh dari Object)
Remove(String)	Menghapus objek konfigurasi dari koleksi.
SetFromList(String)	Mengunci sekumpulan objek konfigurasi berdasarkan daftar yang disediakan.
ToString()	Mengembalikan string yang mewakili objek saat ini. (Diperoleh dari Object)

Implementasi Antarmuka Eksplisit

ICollection.CopyTo(Array, Int32)

Menyalin seluruh ConfigurationLockCollection koleksi ke satu dimensi Arrayyang kompatibel, dimulai pada indeks array target yang ditentukan.
