ConnectionOptions(String, String, SecureString, String, ImpersonationLevel, AuthenticationLevel, Boolean, ManagementNamedValueCollection, TimeSpan)
建立一個新的 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
連線所使用的地點。
- username
- String
連線時要用的使用者名稱。 若為空,則使用目前登入使用者的憑證。
- password
- SecureString
給定的使用者名稱密碼。 若使用者名稱也是空的,則使用的憑證將是目前登入使用者的。
- authority
- String
用於驗證指定使用者的權限。
- impersonation
- ImpersonationLevel
用於連線的 COM 模擬等級。
- authentication
- AuthenticationLevel
COM認證等級將用於連線。
- enablePrivileges
- Boolean
true以啟用特殊使用者權限;否則,則為錯誤。 此參數僅在執行需要特殊 Windows NT 使用者權限的操作時使用。
- context
- ManagementNamedValueCollection
一個提供者專屬的命名值對物件要傳遞給提供者。
- timeout
- TimeSpan
保留供未來使用。
