接口概要

接口	说明
AsyncOperationExecutor	An interface describing the execution of a read or a write operation.
AsyncReadOperation<T>	An operation which asynchronously reads from a MongoDB server.
AsyncWriteOperation<T>	An operation which asynchronously writes to a MongoDB server.
BatchCursor<T>	MongoDB returns query results as batches, and this interface provideds an iterator over those batches.
MapReduceAsyncBatchCursor<T>	Represents the future results of a map-reduce operation as a cursor.
MapReduceBatchCursor<T>	Represents the results of a map-reduce operation as a cursor.
OperationExecutor	An interface describing the execution of a read or a write operation.
ReadOperation<T>	An operation that reads from a MongoDB server.
WriteOperation<T>	An operation which writes to a MongoDB server.

类概要

类	说明
AggregateOperation<T>	An operation that executes an aggregation query.
AggregateToCollectionOperation	An operation that executes an aggregation that writes its results to a collection (which is what makes this a write operation rather than a read operation).
BaseWriteOperation	Abstract base class for write operations.
CommandReadOperation<T>	An operation that executes an arbitrary command that reads from the server.
CommandWriteOperation<T>	An operation that executes an arbitrary command that writes to the server.
CountOperation	An operation that executes a count.
CreateCollectionOperation	An operation to create a collection
CreateIndexesOperation	An operation that creates one or more indexes.
CreateUserOperation	An operation to create a user.
CurrentOpOperation	An operation that determines the current operation on a MongoDB server.
DeleteOperation	An operation that deletes one or more documents from a collection.
DistinctOperation<T>	Finds the distinct values for a specified field across a single collection.
DropCollectionOperation	Operation to drop a Collection in MongoDB.
DropDatabaseOperation	Operation to drop a database in MongoDB.
DropIndexOperation	An operation that drops an index.
DropUserOperation	An operation to remove a user.
FindAndDeleteOperation<T>	An operation that atomically finds and deletes a single document.
FindAndReplaceOperation<T>	An operation that atomically finds and replaces a single document.
FindAndUpdateOperation<T>	An operation that atomically finds and updates a single document.
FindOperation<T>	An operation that queries a collection using the provided criteria.
FsyncUnlockOperation	Unlocks the MongoDB server, allowing write operations to go through.
GroupOperation<T>	Groups documents in a collection by the specified key and performs simple aggregation functions, such as computing counts and sums.
InsertOperation	An operation that inserts one or more documents into a collection.
ListCollectionsOperation<T>	An operation that provides a cursor allowing iteration through the metadata of all the collections in a database.
ListDatabasesOperation<T>	An operation that provides a cursor allowing iteration through the metadata of all the databases for a MongoClient.
ListIndexesOperation<T>	An operation that lists the indexes that have been created on a collection.
MapReduceStatistics	Common statistics returned by running all types of map-reduce operations.
MapReduceToCollectionOperation	Operation that runs a Map Reduce against a MongoDB instance.
MapReduceWithInlineResultsOperation<T>	Operation that runs a Map Reduce against a MongoDB instance.
MixedBulkWriteOperation	An operation to execute a series of write operations in bulk.
ParallelCollectionScanOperation<T>	Return a list of cursors over the collection that can be used to scan it in parallel.
RenameCollectionOperation	An operation that renames the given collection to the new name.
UpdateOperation	An operation that updates a document in a collection.
UpdateUserOperation	An operation that updates a user.
UserExistsOperation	An operation that determines if a user exists.

OrderBy	Enumeration of possible index orders
