skydrive System.Dynamic.DynamicObject

Question

I\'m trying to get a listing of all the folders for a signed in user on SkyDrive.

LiveOperationResult operationResult = await client.GetAsync(\"me/skydrive/file         


        

Answer 1

I think that you receive this because you have declared result using the following code

dynamic result = operationResult.Result;

this will declare result as a new System.Dynamic.DynamicObject so that, when we say

Dictionary<string, object> folderData = (Dictionary<string, object>)result;

You are trying to convert result of type System.Dynamic.DynamicObject to System.Collections.Generic.Dictionary which is not possible and that's why you receive the error.

Thanks,
I hope you find this helpful :)

Answer 2

The problem is that LiveOperationResult.Result isn't necessarily guaranteed to be a Dictionary<string, object>. It is however defined as an IDictionary<string, object>.

Mind you, you don't appear to even need to cast the Result property to a dictionary of any sort; you should be able to use the dynamic variable to directly access the list you want to iterate.

List<object> folders = (List<object>)result.data;
