我正在使用EWS并希望从公司的交换中获取全球地址列表。我知道如何检索个人联系人列表。
API文档中的所有示例都涉及更新用户信息，但没有具体说明如何检索它们。
我甚至尝试过以下方法来列出文件夹但是它没有正确的结果。
private static void ListFolder(ExchangeService svc, FolderId parent, int depth) {
string s;
foreach (var v in svc.FindFolders(parent, new FolderView(int.MaxValue))) {
Folder f = v as Folder;
if (f != null) {
s = String.Format("[{0}]", f.DisplayName);
Console.WriteLine(s.PadLeft(s.Length + (depth * 2)));
ListFolder(svc, f.Id, depth + 1);
try {
foreach (Item i in f.FindItems(new ItemView(20))) {
Console.WriteLine(
i.Subject.PadLeft(i.Subject.Length + ((depth + 1) * 2)));
}
} catch (Exception) {
}
}
}
}
虽然问题已经提出（How to get contact list from Exchange Server?），但这个问题专门用于使用EWS获取全局地址列表，而此问题则要求提供一般性建议。

您可以使用下面的代码段在指定的文件夹中获取ItemType对象 然后将ItemType对象转换为ContactItemType（对于联系人对象）....
/// <summary>
/// gets list of ItemType objects with maxreturncriteria specicification
/// </summary>
/// <param name="esb">ExchangeServiceBinding object</param>
/// <param name="folder">FolderIdType to get items inside</param>
/// <param name="maxEntriesReturned">the max count of items to return</param>
public static List<ItemType> FindItems(ExchangeServiceBinding esb, FolderIdType folder, int maxEntriesReturned)
{
List<ItemType> returnItems = new List<ItemType>();
// Form the FindItem request
FindItemType request = new FindItemType();
request.Traversal = ItemQueryTraversalType.Shallow;
request.ItemShape = new ItemResponseShapeType();
request.ItemShape.BaseShape = DefaultShapeNamesType.AllProperties;
request.ParentFolderIds = new FolderIdType[] { folder };
IndexedPageViewType indexedPageView = new IndexedPageViewType();
indexedPageView.BasePoint = IndexBasePointType.Beginning;
indexedPageView.Offset = 0;
indexedPageView.MaxEntriesReturned = 100;
indexedPageView.MaxEntriesReturnedSpecified = true;
request.Item = indexedPageView;
FindItemResponseType response = esb.FindItem(request);
foreach (FindItemResponseMessageType firmtMessage in response.ResponseMessages.Items)
{
if (firmtMessage.ResponseClass == ResponseClassType.Success)
{
if (firmtMessage.RootFolder.TotalItemsInView > 0)
foreach (ItemType item in ((ArrayOfRealItemsType)firmtMessage.RootFolder.Item).Items)
returnItems.Add(item);
//Console.WriteLine(item.GetType().Name + ": " + item.Subject + ", " + item.DateTimeReceived.Date.ToString("dd/MM/yyyy"));
}
else
{
//handle error log here
}
}
return returnItems;
}

我刚做了一个类似的事情。但是，我无法通过Exchange获取联系人列表，因为这只会使用户拥有邮箱，而不一定是所有用户或组。我最终通过AD
获得了所有用户这里是获取AD中所有联系人的代码。您只需要全局地址列表的folderID，可以使用AD服务器上的ADSI.msc工具并浏览到全局地址列表文件夹，查看属性并获取“声称搜索”的值。在我的系统中，全局地址列表的searchPath是“（＆amp;（objectClass = user）（objectCategory = person）（mailNickname = ）（msExchHomeServerName = ））”
public List<ListItem> SearchAD(string keyword, XmlDocument valueXml)
{
List<ListItem> ewsItems = new List<ListItem>();
using (DirectoryEntry ad = Utils.GetNewDirectoryEntry("LDAP://yourdomain.com"))
{
Trace.Info("searcherをつくる");
using (DirectorySearcher searcher = new DirectorySearcher(ad))
{
if (this.EnableSizeLimit)
{
searcher.SizeLimit = GetMaxResultCount();
if (Utils.maxResultsCount > 1000)
{
searcher.PageSize = 100;
}
}
else
{
searcher.SizeLimit = 1000;
searcher.PageSize = 10;
}
string sisya = Utils.DecodeXml(valueXml.SelectSingleNode("Folder/SearchPath").InnerText); //this is the folder to grab your contacts from. In your case Global Address list
//Container
if(String.IsNullOrEmpty(sisya))
{
return null;
}
keyword = Utils.EncodeLdap(keyword);
string text = Utils.DecodeXml(valueXml.SelectSingleNode("Folder/Text").InnerText);
searcher.Filter = this.CreateFilter(keyword, sisya);
searcher.Sort = new SortOption("DisplayName", System.DirectoryServices.SortDirection.Ascending);
//一つのPropertyをロードすると、全Propertyを取らないようになる
searcher.PropertiesToLoad.Add("SAMAccountName"); //どのPropertyでもいい。
SearchResultCollection searchResults = searcher.FindAll();
foreach (SearchResult searchResult in searchResults)
{
//ListItem contact = null;
using (DirectoryEntry userEntry = searchResult.GetDirectoryEntry())
{
try
{
string schemaClassName = userEntry.SchemaClassName;
switch (schemaClassName)
{
case "user":
case "contact":
string fname = userEntry.Properties["GivenName"].Value == null ? "" : userEntry.Properties["GivenName"].Value.ToString();
string lname = userEntry.Properties["sn"].Value == null ? "" : userEntry.Properties["sn"].Value.ToString();
string dname = userEntry.Properties["DisplayName"][0] == null ? lname + " " + fname : userEntry.Properties["DisplayName"][0].ToString();
//No Mail address
if ((userEntry.Properties["mail"] != null) && (userEntry.Properties["mail"].Count > 0))
{
string sAMAccountName = "";
if(userEntry.Properties["SAMAccountName"].Value != null){
sAMAccountName = userEntry.Properties["SAMAccountName"].Value.ToString();
}
else{
sAMAccountName = userEntry.Properties["cn"].Value.ToString();
}
string contactXml = Utils.ListViewXml(sAMAccountName, UserType.User, Utils.UserXml(fname, lname, userEntry.Properties["mail"].Value.ToString(), dname, null), ServerType.Ad);
ewsItems.Add(new ListItem(dname + "<" + userEntry.Properties["mail"].Value.ToString() + ">", contactXml));
}
else
{
ListItem contact = new ListItem(dname, null);
contact.Enabled = false;
ewsItems.Add(contact);
Trace.Info("追加できないユーザ: " + searchResult.Path);
}
break;
case "group":
ewsItems.Add(new ListItem(userEntry.Properties["DisplayName"].Value.ToString(), Utils.ListViewXml(userEntry.Properties["SAMAccountName"].Value.ToString(), UserType.Group, null, ServerType.Ad)));
break;
default:
userEntry.Properties["SAMAccountName"].Value.ToString());
ewsItems.Add(new ListItem(userEntry.Properties["name"].Value.ToString(), Utils.ListViewXml(userEntry.Properties["SAMAccountName"].Value.ToString(), UserType.Group, null, ServerType.Ad)));
break;
}
}
catch (Exception ex)
{
Trace.Error("User data取得失敗", ex);
}
}
}
searchResults.Dispose();
}
}
return ewsItems;
}
