Problem in iterating sharepoint folder content

Question

Hi,

I am trying to access Folder from Document Library using web services in C#. I am using SiteData's EnumerateFolder() method to get sub folders and files. But the method gives me only 3 properties for each entry.

1. IsFolder
2. Url
3. Last modified date

So how can we get 'Modified By' field value.

Or there is another solution for enumerating folders and subfolders.

Thanks.

You need to use the List API in order to get more properties from your objects.

[Edit - complete code sample]

The sample needs to be cleaned up, but should give you what you need

public void SomeFunction()
{
    Lists lists = new Lists(); //http://server/_vti_bin/Lists.asmx

    XmlNode coll = lists.GetListCollection();

    XmlNamespaceManager nsMgr = new XmlNamespaceManager(coll.OwnerDocument.NameTable);
    nsMgr.AddNamespace("sp", "http://schemas.microsoft.com/sharepoint/soap/");
    nsMgr.AddNamespace("z", "#RowsetSchema");

    XmlDocument xmlDoc = new XmlDocument();
    XmlElement query = xmlDoc.CreateElement("Query");
    XmlElement viewFields = xmlDoc.CreateElement("ViewFields");
    XmlElement queryOptions = xmlDoc.CreateElement("QueryOptions");

    viewFields.InnerXml = "<FieldRef Name=\"Modified_x0020_By\" />";
    queryOptions.InnerXml = "<ViewAttributes Scope=\"RecursiveAll\"/>";

    XmlNodeList siteLists = coll.SelectNodes("//sp:List", nsMgr);
    foreach (XmlNode list in siteLists)
    {
        if (list.Attributes["ServerTemplate"].Value != "101") continue; //101=DocLib
        XmlNode listItemCollection = lists.GetListItems(list.Attributes["Name"].Value, string.Empty, query,
                                                        viewFields, "4000",
                                                        queryOptions, null);

        XmlNodeList listItems = listItemCollection.SelectNodes("//z:row", nsMgr);
        foreach (XmlNode listItem in listItems)
        {
            if (listItem.Attributes["ows_FSObjType"] == null) continue;
            if (!listItem.Attributes["ows_FSObjType"].Value.EndsWith("#1")) continue;
            PrintModifiedBy(listItem);
        }
    }
}

private void PrintModifiedBy(XmlNode listItem)
{
    string modifiedBy;
    if (listItem.Attributes["Modified_x0020_By"] != null)
        modifiedBy = listItem.Attributes["ows_Modified_x0020_By"].Value;
    else
        modifiedBy = listItem.Attributes["ows_Editor"].Value;
    Console.WriteLine(modifiedBy);
}
