I've written a query to read some stuff from Active Directory, but the result is some kind of "ResultPropertyCollection", which is something I'm not familiar with.
How can I convert this result to a list (like Generic List) that I'm more familiar with so I can do something with the results?
DirectoryEntry de = new DirectoryEntry("LDAP://" + this.rootLDAP);
DirectorySearcher ds = new DirectorySearcher(de, "(& (objectcategory=Group))");
ds.PropertiesToLoad.Add("samaccountname");
ds.PropertiesToLoad.Add("memberof");
ds.PropertiesToLoad.Add("samaccounttype");
ds.PropertiesToLoad.Add("grouptype");
ds.PropertiesToLoad.Add("member");
ds.PropertiesToLoad.Add("objectcategory");
var r = ( from SearchResult sr in ds.FindAll() select sr ) .ToArray(); If you only want a list of SearchResult types, you could use:
var r = ds.FindAll();
List<SearchResult> results = new List<SearchResult>();
foreach (SearchResult sr in r)
{
results.Add(sr);
}
But since you want the actual values from the search results, you need to do more work.
Basically, that collection contains all the properties you've defined for the search - at least as long as they contain a value!
So really, what you need to do is create a class to hold those values. The two elements memberOf and member can themselves contain multiple values (they're "multi-valued" attributes in AD) - so you'll need a list of strings for these:
public class YourType
{
public string SamAccountName { get; set; }
public int SamAccountType { get; set; }
public int GroupType { get; set; }
public string ObjectCategory { get; set; }
public List<string> MemberOf { get; set; }
public List<string> Member { get; set; }
}
Then, once you have your search result, you need to iterate over the results and create new instances of YourType for each search result, and stick those into a List<YourType>:
foreach(SearchResult sr in ds.FindAll())
{
YourType newRecord = ConvertToYourType(sr);
}
and in that method, you need to inspect the .Properties collection for each value and extract it:
public YourType ConvertToYourType(SearchResult result)
{
YourType returnValue = new YourType();
returnValue.MemberOf = new List<string>();
returnValue.Member = new List<string>();
if(result.Properties["samAccountName"] != null && result.Properties["samAccountName"].Count > 0)
{
returnValue.SamAccountName = result.Properties["samAccountName"][0].ToString();
}
// ..... and so on for each of your values you need to extract
return returnValue;
}
