How to Reflect on Dynamic Objects' Properties in .NET?

.NET dynamic object property reflection

In .NET, when working with dynamic objects, introspecting their properties presents unique challenges. Regular reflection techniques may not be used to retrieve property values.

Problem Statement:

How to get a dictionary of attribute names and their corresponding values ​​from a dynamic object declared using the dynamic keyword?

Solution using ExpandoObject:

For dynamic objects of type ExpandoObject, there is a simple solution. The ExpandoObject class itself implements the IDictionary interface for its properties. Therefore, we can cast the dynamic object to IDictionary to access the property value.

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

Note: This method only works on ExpandoObject instances. For other types of dynamic objects, alternative methods are required.
