Remarks

When using the getter of this indexer, if the key is not present in this entity's set of properties, null is returned.

When using the setter of the indexer, setting a null value removes the property if it is present. To explicitly set a null value, use ForNull().

Key

public Key Key { get; set; }

An entity must have a key, unless otherwise documented (for example, an entity in Value.entity_value may have no key). An entity's kind is its key path's last element's kind, or null if it has no key.

Property Value
Type	Description
`Key`

Properties

public MapField<string, Value> Properties { get; }

The entity's properties. The map's keys are property names. A property name matching regex __.*__ is reserved. A reserved property name is forbidden in certain documented contexts. The name must not contain more than 500 characters. The name cannot be "".
