Unable to fetch some group properties via C# SDK

Question

I am trying to fetch groups via graph api and get resourceBehaviorOptions and resourceProvisioningOptions properties. Eventhough these properties exist in the direct graph api response, I am unable to find them when I use c# graph SDK. I can see these properties existing under AdditionalData but value is empty even though graph response had values.

var graphClient = new GraphServiceClient(accessTokenCredential);
GroupCollectionResponse
{
  requestConfiguration.QueryParameters.Count = true;
  requestConfiguration.Headers.Add("ConsistencyLevel", "eventual");
});

foreach (var group in groups.Value)
{
  Console.WriteLine(JsonSerializer.Serialize(group.AdditionalData["resourceProvisioningOptions"]));
  #always gives {}
}

I also found separate api request to fetch resourceBehaviorOptions via https://graph.microsoft.com/v1.0/groups/{group_id}/resourceProvisioningOptions but the value is still empty.

How can I fetch these property values using graph SDK?

Hi @Yasitha Pandithawatta

Try this code:

// Code snippets are only available for the latest version. Current version is 5.x
// To initialize your graphClient, see https://learn.microsoft.com/en-us/graph/sdks/create-client?from=snippets&tabs=csharp
var result = await graphClient.Groups["{group-id}"].GetAsync((requestConfiguration) =>
{
	requestConfiguration.QueryParameters.Select = new string []{"resourceBehaviorOptions","resourceProvisioningOptions" };
});

Note that make sure the property has a value.

When I debug the response object, I can see these properties exist under additionalData as non-public properties, even in the initial /groups API request. I wrote the code snippet below and was able to retrieve them.

if (group.AdditionalData != null && group.AdditionalData.TryGetValue("resourceProvisioningOptions", out object provisioningOptionsObj))
        {
            if (provisioningOptionsObj is UntypedArray untypedArray)
            {
                var valueField = untypedArray.GetType().GetField("_value", BindingFlags.NonPublic | BindingFlags.Instance);
                if (valueField != null)
                {
                    var enumerable = valueField.GetValue(untypedArray) as IEnumerable;

                    if (enumerable != null)
                    {
                        foreach (var item in enumerable)
                        {
                            if (item is UntypedString untypedString)
                            {
                                var stringValueField = untypedString.GetType().GetField("_value", BindingFlags.NonPublic | BindingFlags.Instance);

                                if (stringValueField != null)
                                {
                                    var actualValue = stringValueField.GetValue(untypedString) as string;
                                    Console.WriteLine(actualValue);
                                }
                            }
                        }
                    }
                }
            }
        }
