public static bool TryGetAllValuesForPropertyChain(out IObservedChange<object, object?>[] changeValues, object? current, IEnumerable<Expression> expressionChain)
Summary: Based on a list of expressions, attempts to produce an array of IObservedChange values representing each step in the property chain.
Parameters
| Name | Type | Description |
|---|---|---|
out changeValues | IObservedChange<object, object?>[] | Receives an array with one entry per expression in the chain. |
current | object? | The object that starts the property chain. |
expressionChain | IEnumerable | A sequence of expressions that point to properties/fields. |
Returns: bool -- true if all values were successfully retrieved; otherwise false.
Remarks
This preserves the existing behavior: on early failure, the method writes a single null
element at the failing index and returns false.
Exceptions
| Type | Condition |
|---|---|
| System.InvalidOperationException | Thrown when expressionChain is empty. |
| System.ArgumentNullException | Thrown when expressionChain is null. |
