Class MemberSelectorBuilder
- Namespace
- Bonsai.Expressions
- Assembly
- Bonsai.Core.dll
Represents an expression builder that defines a simple selector on the elements of an observable sequence by mapping specified member values into the output data type.
The MemberSelector operator is used to quickly extract member fields and properties out of the elements of the source sequence. Multiple members can be specified using a comma-separated list in the Selector property, in which case the output type will be a tuple of all selected member types.
The TypeMapping property can be used to specify which type conversion to use when chaining the selected members into downstream operators.
