It is implemented as an internal dictionary.

Check out Alexander Rusina’s blog on the topic here , and mine.

You do not need to bother with Reflector, the DLR source code is easily available for download here . Wonderfully commented. You will find the source code for ExpandoObject in src \ Runtime \ Microsoft.Scripting.Core \ Actions \ ExpandoObject.cs

The data store for ExpandoObject is ExpandoData, available in the same source file. Values ​​are stored in a simple object []. ExpandoClass (the same directory) tracks keys in a simple string []. ExpandoObject definitely doesn’t use a dictionary, as mentioned earlier, but it implements IDictionary.
