Methods

Constant<TValue>(TValue, BsonType): Use this method in a MongoDB LINQ query when you need to specify how a constant should be serialized.

Constant<TValue>(TValue, IBsonSerializer<TValue>): Use this method in a MongoDB LINQ query when you need to specify how a constant should be serialized.

Convert<TFrom, TTo>(TFrom, ConvertOptions<TTo>): Converts a value from one type to another using the $convert aggregation operator.

CreateObjectId(): Creates a new unique ObjectId using the $createObjectId aggregation operator.

DateFromString(string): Converts a string to a DateTime using the $dateFromString aggregation operator.

DateFromString(string, string): Converts a string to a DateTime using the $dateFromString aggregation operator.

DateFromString(string, string, string): Converts a string to a DateTime using the $dateFromString aggregation operator.

DateFromString(string, string, string, DateTime?, DateTime?): Converts a string to a DateTime using the $dateFromString aggregation operator.

DeserializeEJson<TInput, TOutput>(TInput, DeserializeEJsonOptions<TOutput>): Deserializes Extended JSON values back to native BSON types using the $deserializeEJSON aggregation operator.

Exists<TField>(TField): Tests whether a field exists.

Field<TDocument, TField>(TDocument, string, IBsonSerializer<TField>): Gets the value of a field in a document.

Hash<TValue>(TValue, MqlHashAlgorithm): Generates a binary hash for an input expression.

HexHash<TValue>(TValue, MqlHashAlgorithm): Generates a hexadecimal hash string for an input expression.

IsMissing<TField>(TField): Tests whether a field is missing.

IsNullOrMissing<TField>(TField): Tests whether a field is null or missing.

SerializeEJson<TInput, TOutput>(TInput, SerializeEJsonOptions<TOutput>): Serializes BSON values to their Extended JSON v2 representation using the $serializeEJSON aggregation operator.

Sigmoid(double): Transforms a real-valued input into a value between 0 and 1 using the $sigmoid operator.

SimilarityCosine<TElement>(IEnumerable<TElement>, IEnumerable<TElement>, bool): Translated to the "$similarityCosine" operator in MQL to measure the similarity between two vectors.

SimilarityCosine<TElement>(ReadOnlyMemory<TElement>, ReadOnlyMemory<TElement>, bool): Translated to the "$similarityCosine" operator in MQL to measure the similarity between two vectors.

SimilarityDotProduct<TElement>(IEnumerable<TElement>, IEnumerable<TElement>, bool): Translated to the "$similarityDotProduct" operator in MQL to measure the similarity between two vectors.

SimilarityDotProduct<TElement>(ReadOnlyMemory<TElement>, ReadOnlyMemory<TElement>, bool): Translated to the "$similarityDotProduct" operator in MQL to measure the similarity between two vectors.

SimilarityEuclidean<TElement>(IEnumerable<TElement>, IEnumerable<TElement>, bool): Translated to the "$similarityEuclidean" operator in MQL to measure the similarity between two vectors.

SimilarityEuclidean<TElement>(ReadOnlyMemory<TElement>, ReadOnlyMemory<TElement>, bool): Translated to the "$similarityEuclidean" operator in MQL to measure the similarity between two vectors.

Subtype<TValue>(TValue): Returns the subtype of a given binary value.
