The pipeline.
partitionBy: Type: MongoDB.DriverAggregateExpressionDefinitionTIntermediate, TPartitionBy
The partitionBy expression.
output: Type: MongoDB.DriverAggregateExpressionDefinitionISetWindowFieldsPartitionTIntermediate, TWindowFields
The window fields expression.

Type Parameters

TInput: The type of the input documents.
TIntermediate: The type of the intermediate documents.
TPartitionBy: The type of the value to partition by.
TWindowFields: The type of the added window fields.

Return Value

Type: PipelineDefinitionTInput, BsonDocument
The stage.

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type PipelineDefinitionTInput, TIntermediate. When you use instance method syntax to call this method, omit the first parameter. For more information, see Extension Methods (Visual Basic) or Extension Methods (C# Programming Guide).
