'Declaration
Public Class ConnectionOptions _
	Inherits ManagementOptions

The ConnectionOptions type exposes the following members.

  NameDescription
Public methodConnectionOptionsInitializes a new instance of the ConnectionOptions class for the connection operation, using default values. This is the default constructor.
Public methodConnectionOptions(String, String, SecureString, String, ImpersonationLevel, AuthenticationLevel, Boolean, ManagementNamedValueCollection, TimeSpan)Creates a new ConnectionOption.
Public methodConnectionOptions(String, String, String, String, ImpersonationLevel, AuthenticationLevel, Boolean, ManagementNamedValueCollection, TimeSpan)Initializes a new instance of the ConnectionOptions class to be used for a WMI connection, using the specified values.

  NameDescription
Public propertyAuthenticationGets or sets the COM authentication level to be used for operations in this connection.
Public propertyAuthorityGets or sets the authority to be used to authenticate the specified user.
Public propertyContextGets or sets a WMI context object. This is a name-value pairs list to be passed through to a WMI provider that supports context information for customized operation. (Inherited from ManagementOptions.)
Public propertyEnablePrivilegesGets or sets a value indicating whether user privileges need to be enabled for the connection operation. This property should only be used when the operation performed requires a certain user privilege to be enabled (for example, a machine restart).
Public propertyImpersonationGets or sets the COM impersonation level to be used for operations in this connection.
Public propertyLocaleGets or sets the locale to be used for the connection operation.
Public propertyPasswordSets the password for the specified user.
Public propertySecurePasswordSets the password for the specified user.
Public propertyTimeoutGets or sets the time-out to apply to the operation. Note that for operations that return collections, this time-out applies to the enumeration through the resulting collection, not the operation itself (the ReturnImmediately property is used for the latter). This property is used to indicate that the operation should be performed semi-synchronously. (Inherited from ManagementOptions.)
Public propertyUsernameGets or sets the user name to be used for the connection operation.

  NameDescription
Public methodCloneReturns a copy of the object. (Overrides ManagementOptions.Clone.)
Public methodEquals(Object)Determines whether the specified object is equal to the current object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeServes as the default hash function. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)
