Remarks

The DynamicRecord class makes it possible to read data record values by using the familiar indexing and member-access syntax of the host language.

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
