The MongoCursor type exposes the following members.

Constructors

	Name	Description
	MongoCursor(MongoCollection, IMongoQuery, ReadPreference, IBsonSerializer)	Creates a new MongoCursor. It is very unlikely that you will call this constructor. Instead, see all the Find methods in MongoCollection.
	MongoCursor(MongoCollection, IMongoQuery, ReadConcern, ReadPreference, IBsonSerializer)	Initializes a new instance of the MongoCursor class.

Properties

	Name	Description
	BatchSize	Gets or sets the batch size (the number of documents returned per batch).
	Collation	Gets the collation.
	Collection	Gets the collection that is being queried.
	Database	Gets the database that constains the collection that is being queried.
	Fields	Gets or sets the fields that will be returned from the server.
	Flags	Gets or sets the query flags.
	IsFrozen	Gets whether the cursor has been frozen to prevent further changes.
	Limit	Gets or sets the limit on the number of documents to be returned.
	MaxAwaitTime	Gets or sets the maximum await time for TailableAwait cursors.
	Options	Gets or sets the cursor options. See also the individual Set{Option} methods, which are easier to use.
	Query	Gets the query that will be sent to the server.
	ReadConcern	Gets the read concern.
	ReadPreference	Gets or sets the read preference.
	Serializer	Gets the serializer.
	Server	Gets the server that the query will be sent to.

Methods

	Name	Description
	Clone(Type)	Creates a clone of the cursor.
	Clone(Type, IBsonSerializer)	Creates a clone of the cursor.
	CloneTDocument	Creates a clone of the cursor.
	CloneTDocument(IBsonSerializer)	Creates a clone of the cursor.
	Count	Returns the number of documents that match the query (ignores Skip and Limit, unlike Size which honors them).
	Create(Type, MongoCollection, IMongoQuery, ReadPreference, IBsonSerializer)	Obsolete. Creates a cursor.
	Create(Type, MongoCollection, IMongoQuery, ReadConcern, ReadPreference, IBsonSerializer)	Obsolete. Creates a cursor.
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	Explain	Returns an explanation of how the query was executed (instead of the results).
	Explain(Boolean)	Returns an explanation of how the query was executed (instead of the results).
	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.)
	IEnumerableGetEnumerator	Gets the non-generic enumerator.
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	SetBatchSize	Sets the batch size (the number of documents returned per batch).
	SetCollation	Sets the collation.
	SetFields(String)	Sets the fields that will be returned from the server.
	SetFields(IMongoFields)	Sets the fields that will be returned from the server.
	SetFlags	Sets the query flags.
	SetHint(String)	Sets the index hint for the query.
	SetHint(BsonDocument)	Sets the index hint for the query.
	SetLimit	Sets the limit on the number of documents to be returned.
	SetMax	Sets the max value for the index key range of documents to return (note: the max value itself is excluded from the range). Often combined with SetHint (if SetHint is not used the server will attempt to determine the matching index automatically).
	SetMaxAwaitTime	Sets the maximum await time for tailable await cursors.
	SetMaxScan	Obsolete. Sets the maximum number of documents to scan.
	SetMaxTime	Sets the maximum time the server should spend on this query.
	SetMin	Sets the min value for the index key range of documents to return (note: the min value itself is included in the range). Often combined with SetHint (if SetHint is not used the server will attempt to determine the matching index automatically).
	SetOption	Sets a cursor option.
	SetOptions	Sets multiple cursor options. See also the individual Set{Option} methods, which are easier to use.
	SetReadPreference	Sets the read preference.
	SetSerializer	Sets the serializer.
	SetShowDiskLoc	Sets the $showDiskLoc option.
	SetSkip	Sets the number of documents the server should skip before returning the rest of the documents.
	SetSnapshot	Obsolete. Sets the $snapshot option.
	SetSortOrder(String)	Sets the sort order for the server to sort the documents by before returning them.
	SetSortOrder(IMongoSortBy)	Sets the sort order for the server to sort the documents by before returning them.
	Size	Returns the size of the result set (honors Skip and Limit, unlike Count which does not).
	ToString	Returns a string that represents the current object. (Inherited from Object.)
