| Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
| GetHashCode | Serves as the default hash function. (Inherited from Object.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
| Render(IBsonSerializer<TSource>, IBsonSerializerRegistry) |
Renders the projection to a RenderedProjectionDefinition<TProjection>.
|
| Render(IBsonSerializer<TSource>, IBsonSerializerRegistry, LinqProvider) |
Renders the projection to a RenderedProjectionDefinition<TProjection>.
|
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
Operators| Name | Description | |
|---|---|---|
