| Name | Description | |
|---|---|---|
 | Associations | Gets an enumeration of all the associations. |
| CanInstantiate | Gets whether the underlying type can be instantiated as the result of a query. |
| DataMembers | Gets an enumeration of all the data members (fields and properties). |
| DBGeneratedIdentityMember | Gets the member that represents the auto-generated identity column. |
| DerivedTypes | Gets an enumeration of the immediate derived types in an inheritance hierarchy. |
| Discriminator | Gets the member that represents the inheritance discriminator column. |
| HasAnyLoadMethod | Gets a value that indicates whether the current MetaType or any of its bases types has an OnLoaded method. |
| HasAnyValidateMethod | Gets a value that indicates whether the MetaType or any of its bases types has an OnValidate method. |
| HasInheritance | Gets a value indicating whether the type is part of a mapped inheritance hierarchy. |
| HasInheritanceCode | Gets a value indicating whether this type defines an inheritance code. |
| HasUpdateCheck | Gets a value indicating whether the type has any persistent member that may require a test for optimistic concurrency conflicts. |
| IdentityMembers | Gets an enumeration of all the data members that define the unique identity of the type. |
| Indexes | Gets a read-only collection of MetaType indexes. |
| InheritanceBase | Gets the base meta-type in the inheritance hierarchy. |
| InheritanceCode | Gets a value indicating whether this type defines an inheritance code. |
| InheritanceDefault | Gets a value indicating whether this type is used as the default of an inheritance hierarchy. |
| InheritanceRoot | Gets the root type of the inheritance hierarchy. |
| InheritanceTypes | Gets a collection of all types that are defined by an inheritance hierarchy. |
| IsEntity | Gets a value indicating whether the MetaType is an entity type. |
| IsInheritanceDefault | Gets a value indicating whether this type is used as the default of an inheritance hierarchy. |
| Model | Gets the MetaModel that contains this MetaType. |
| Name | Gets the name of the MetaType. |
| OnLoadedMethod | Gets information about the OnLoaded method contained by this meta-type. |
| OnValidateMethod | Gets information about the OnValidate method contained by this meta-type. |
| PersistentDataMembers | Gets a collection of all the persistent data members. |
| Table | Gets the MetaTable that uses this MetaType for row definition. |
| Type | Gets the underlying common language runtime (CLR) type. |
| VersionMember | Gets a row-version or timestamp column for this MetaType. |
| Name | Description | |
|---|---|---|
 | Equals(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
 | Finalize | Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.) |
| GetDataMember | Gets the MetaDataMember associated with the specified member. |
| GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
| GetInheritanceType | Gets the MetaType for an inheritance subtype. |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| GetTypeForInheritanceCode | Gets the meta-type associated with the specified inheritance code. |
