ConnectionOptions(String, String, SecureString, String, ImpersonationLevel, AuthenticationLevel, Boolean, ManagementNamedValueCollection, TimeSpan)
建立新的 ConnectionOption。
public:
ConnectionOptions(System::String ^ locale, System::String ^ username, System::Security::SecureString ^ password, System::String ^ authority, System::Management::ImpersonationLevel impersonation, System::Management::AuthenticationLevel authentication, bool enablePrivileges, System::Management::ManagementNamedValueCollection ^ context, TimeSpan timeout);

Public Sub New (locale As String, username As String, password As SecureString, authority As String, impersonation As ImpersonationLevel, authentication As AuthenticationLevel, enablePrivileges As Boolean, context As ManagementNamedValueCollection, timeout As TimeSpan)
參數
- locale
- String
要用於連接的地區設定 (Locale)。
- username
- String
要用於連接的使用者名稱。 如果是 Null,則會使用目前登入使用者的認證。
- password
- SecureString
指定使用者名稱的密碼。 如果使用者名稱也是 Null,則使用的認證將是目前登入使用者的認證。
- authority
- String
要用來驗證指定使用者的授權。
- impersonation
- ImpersonationLevel
要用於連接的 COM 模擬等級。
- authentication
- AuthenticationLevel
要用於連接的 COM 驗證 (Authentication) 等級。
- enablePrivileges
- Boolean
true 表示啟用特殊的使用者權限,否則為 false。 在執行需要特殊 Windows NT 使用者權限的作業時才會使用這個參數。
- context
- ManagementNamedValueCollection
要經由提供者傳送的特定提供者 (Provider) 具名值配對物件。
- timeout
- TimeSpan
保留供未來使用。
