Methods
  NameDescription
Public methodAppendStageTNewResult
Appends the stage to the pipeline.
Public methodAsTNewResult
Changes the result type of the pipeline.
Public methodBucketTValue(AggregateExpressionDefinitionTResult, TValue, IEnumerableTValue, AggregateBucketOptionsTValue)
Appends a $bucket stage to the pipeline.
Public methodBucketTValue, TNewResult(AggregateExpressionDefinitionTResult, TValue, IEnumerableTValue, ProjectionDefinitionTResult, TNewResult, AggregateBucketOptionsTValue)
Appends a $bucket stage to the pipeline with a custom projection.
Public methodBucketAutoTValue(AggregateExpressionDefinitionTResult, TValue, Int32, AggregateBucketAutoOptions)

Appends a lookup stage to the pipeline.
Public methodMatch
Appends a match stage to the pipeline.
Public methodMergeTOutput
Appends a merge stage to the pipeline and executes it, and then returns a cursor to read the contents of the output collection.

Appends a merge stage to the pipeline and executes it, and then returns a cursor to read the contents of the output collection.
Public methodOfTypeTNewResult
Appends a match stage to the pipeline that matches derived documents and changes the result type to the derived type.
Public methodOut
Appends an out stage to the pipeline and executes it, and then returns a cursor to read the contents of the output collection.
Public methodOutAsync
Appends an out stage to the pipeline and executes it, and then returns a cursor to read the contents of the output collection.

Public methodReplaceWithTNewResult
Appends a $replaceWith stage to the pipeline.
Public methodSkip
Appends a skip stage to the pipeline.
Public methodSort
Appends a sort stage to the pipeline.
Public methodSortByCountTId
Appends a sortByCount stage to the pipeline.
Public methodToCursor
Executes the operation and returns a cursor to the results.
(Inherited from IAsyncCursorSourceTDocument.)
Public methodToCursorAsync
Executes the operation and returns a cursor to the results.
(Inherited from IAsyncCursorSourceTDocument.)
Public methodUnwindTNewResult(FieldDefinitionTResult, IBsonSerializerTNewResult) Obsolete.
