How to Retrieve Properties from Dynamic Objects in .NET?

Accessing Properties of Dynamic Objects in .NET

Question: Accessing Properties in .NET Dynamic Objects

.NET developers often encounter situations where accessing properties of dynamic objects is necessary. Standard reflection techniques, however, may prove ineffective with dynamic objects. This question explores this challenge and seeks a solution within the .NET 4 framework.

Answer: Leveraging the IDictionary Interface

For ExpandoObject instances, a straightforward solution exists. ExpandoObject implements the IDictionary<string, object> interface, allowing direct property access via casting:

<code class="language-csharp">IDictionary<string, object> propertyValues = (IDictionary<string, object>)s;</code>

This method, however, is exclusively applicable to ExpandoObject and won't generalize to other dynamic object types.

Addressing General Dynamic Objects

Handling arbitrary dynamic objects (beyond ExpandoObject) necessitates more sophisticated approaches. These typically involve utilizing the Dynamic Language Runtime (DLR) and the IDynamicMetaObjectProvider interface to dynamically retrieve property values. The specific implementation would depend on the nature of the dynamic object in question.
