Açıklamalar

İstemci uygulamaları, tüm kullanıcılar için geçerli olan genel bir yapılandırmayı, tek tek kullanıcılar için geçerli olan ayrı yapılandırmaları ve gezici kullanıcılar için geçerli olan yapılandırmaları kullanır. userLevel parametresi, kullanıcı düzeyi (yapılandırma dosyası uygulamayla aynı dizinde) veya kullanıcı düzeyi (yapılandırma dosyası kullanıcı düzeyi tarafından belirlenen bir uygulama ayarları yolunda) olup olmadığını belirterek açılan yapılandırma dosyasının konumunu belirler.

için userLevelaşağıdaki değerlerden birini geçirerek hangi yapılandırmanın alınacağını belirtin:

• Tüm kullanıcılar için geçerli olan nesneyi almak Configuration için olarak ayarlayın userLevelNone.

• Geçerli kullanıcıya uygulanan yerel Configuration nesneyi almak için olarak ayarlayın userLevelPerUserRoamingAndLocal.

• Geçerli kullanıcıya uygulanan dolaşım Configuration nesnesini almak için olarak ayarlayın userLevelPerUserRoaming.

  Not

  Bir kaynağın Configuration nesnesini almak için kodunuzun ayarları devraldığı tüm yapılandırma dosyaları üzerinde okuma izinlerine sahip olması gerekir. Bir yapılandırma dosyasını güncelleştirmek için kodunuzun hem yapılandırma dosyası hem de bulunduğu dizin için yazma izinlerine sahip olması gerekir.
