Assembly: Microsoft.Office.Interop.Outlook (in Microsoft.Office.Interop.Outlook.dll)
This is a .NET interface derived from a COM coclass that is required by managed code for interoperability with the corresponding COM object. Use this derived interface to access all method, property, and event members of the COM object. However, if a method or event you want to use shares the same name under the same COM object, cast to the corresponding primary interface to call the method, and cast to the latest events interface to connect to the event. Refer to this topic for information about the COM object. For information about the method and property members of the COM object, see _ToOrFromRuleCondition.
ToOrFromRuleCondition is derived from the RuleCondition object. Each rule is associated with a RuleConditions object which has a SentTo property and a From. Each of these properties always returns a ToOrFromRuleCondition object. ToOrFromRuleCondition.ConditionType distinguishes between these rule conditions. If the rule has any of these rule conditions enabled, then _ToOrFromRuleCondition.Enabled would be True.
For more information on specifying rule conditions, see Specifying Rule Conditions.
