如何从Outlook里获得用户的名字和头像

今天share一下如何从outlook里获得缩略图和全名的两个方法。方法的难点是如何从SearchResult 里获得想要的信息。因为这个结果里有大量信息。目前我还没有找到一个很好的方法来处理。找到后我会补全这块的信息。方法仅供参考。

private static string GetThumnailImage(string domain, string alias)
{
Bitmap thumnailImage = null;
DirectorySearcher dirSearcher = new DirectorySearcher();
DirectoryEntry rootEntry = new DirectoryEntry("LDAP://fareast.corp.microsoft.com");
dirSearcher.SearchRoot = rootEntry;
dirSearcher.Filter = string.Format("(|(sAMAccountName={0})(cn={0}))", alias);
dirSearcher.SearchScope = SearchScope.Subtree;

SearchResultCollection searchResultColl = dirSearcher.FindAll();
string imagePath = AppDomain.CurrentDomain.BaseDirectory + "thumbnailphoto.png";
if (searchResultColl.Count <= 0)
{
throw new System.Security.Authentication.AuthenticationException();
}
SearchResult result = searchResultColl[0];
if (result == null || result.Properties == null)
{
throw new System.Security.Authentication.AuthenticationException();
}
if (result.Properties["thumbnailphoto"] != null && result.Properties["thumbnailphoto"].Count > 0)
{
byte[] imageBytes = new byte[((byte[])result.Properties["thumbnailphoto"][0]).Count<byte>()];
Array.Copy((byte[])result.Properties["thumbnailphoto"][0], imageBytes, imageBytes.Count<byte>());
using (System.IO.MemoryStream mmStream = new System.IO.MemoryStream(imageBytes))
{
thumnailImage = new System.Drawing.Bitmap(mmStream);
mmStream.Flush();
thumnailImage.Save(imagePath);
}
}

return imagePath;
}

private static string GetFullName(string domain, string alias)
{
DirectorySearcher dirSearcher = new DirectorySearcher();
DirectoryEntry rootEntry = new DirectoryEntry("LDAP://fareast.corp.microsoft.com");
dirSearcher.SearchRoot = rootEntry;
dirSearcher.Filter = string.Format("(|(sAMAccountName={0})(cn={0}))", alias);
dirSearcher.SearchScope = SearchScope.Subtree;

SearchResultCollection searchResultColl = dirSearcher.FindAll();

string name = string.Empty;
if (searchResultColl.Count <= 0)
{
throw new System.Security.Authentication.AuthenticationException();
}
SearchResult result = searchResultColl[0];
if (result == null || result.Properties == null)
{
throw new System.Security.Authentication.AuthenticationException();
}
if (result.Properties["givenname"] != null && result.Properties["givenname"].Count > 0)
{
name = result.Properties["givenname"][0].ToString();
}
if (result.Properties["sn"] != null && result.Properties["sn"].Count > 0)
{
name += " " + result.Properties["sn"][0].ToString();
}

return name;
}
