Parent | Gets or sets the Database object that is the parent of the Rule object. | |
Properties | Gets a collection of Property objects that represent the object properties. (从 SqlSmoObject 继承。) | |

Schema | Gets or sets the schema. (从 ScriptSchemaObjectBase 继承。) | |
State | Gets the state of the referenced object. (从 SmoObjectBase 继承。) | |
TextBody | Gets or sets the text that defines the default or rule. (从 DefaultRuleBase 继承。) | |
TextHeader | Gets or sets the header of the text body that defines the default or rule. (从 DefaultRuleBase 继承。) | |
TextMode | Gets or sets the Boolean property value that specifies whether the Default object or Rule object header is editable as text. (从 DefaultRuleBase 继承。) | |
