![]() | CurrentValue | Gets the current value of the member in conflict. |
![]() | DatabaseValue | Gets the database value of the member in conflict. |
![]() | IsModified | Gets a value that indicates whether the member data has been changed since the last database read or refresh. |
![]() | IsResolved | Gets a value that indicates whether the conflict has been resolved. |
![]() | Member | Gets metadata information about the member in conflict. |
![]() | OriginalValue | Gets the original value of the member in conflict. |

![]() | 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 it is reclaimed by garbage collection. (Inherited from Object.) |
