Microsoft 图 api 在部门字段中返回 NULL

Question

I have given all required permissions for retrieving user info from Azure active directory like User.Read.All and User.Read but still getting Department and EmployeeId field as NULL

code used:

public Microsoft.Graph.User GetUser(ref GraphServiceClient graphServiceClient, string UserId)
    {
        return graphServiceClient.Users[UserId].Request().GetAsync().Result;

    }

Answer 1

According to the documentation both department and employeeId are returned only on $select .

Use Select method and specify those two properties. If you need to return more properties, they need to be specified in Select . Without using Select , Graph API return only default set of properties.

public Microsoft.Graph.User GetUser(ref GraphServiceClient graphServiceClient, string UserId)
{
    return graphServiceClient.Users[UserId]
             .Request()
             .Select("department,employeeId")
             .GetAsync()
             .Result;
}
