Voici un code en C# qui vous permettra d'obtenir la taille d'une boîte aux lettres Exchange. Le résultat retourné est identique à celui que vous retrouvez dans l'ESM (Exchange System Manager).
Ce code reprend simplement le code proposé dans cet article technique : http://support.microsoft.com/default.aspx?scid=kb;en-us;320071
Sous Visual Studio, créez une solution de type "Console Application" appélée RecursiveLoopFolders, ajoutez une classe que vous nommerez WebDAVSize.cs. Copier/coller dans cette classe le code suivant:
using System;
using System.Net;
using System.IO;
using System.Text;
using System.Xml;
namespace RecursiveLoopPublicFolders
{
public class WebDAVSize
{
static public long FolderSize(string URL, string userName, string userPassword, string userDomain)
{
System.Net.HttpWebRequest Request;
System.Net.WebResponse Response;
System.Net.CredentialCache MyCredentialCache;
string strQuery ="";
byte[] bytes = null;
System.IO.Stream RequestStream = null;
System.IO.Stream ResponseStream = null;
XmlDocument ResponseXmlDoc = null;
XmlNodeList oXMLSizeNodes = null;
XmlNodeList oXMLHREFNodes = null;
XmlNodeList oXMLHasSubsNodes = null;
long totalSize=0;
try
{
strQuery = @"<?xml version=""1.0""?>";
strQuery += @"<g:searchrequest xmlns:g=""DAV:"">";
strQuery += @"<g:sql>SELECT ""http://schemas.microsoft.com/";
strQuery += @"mapi/proptag/x0e080003"", ""DAV:hassubs"" FROM SCOPE ";
strQuery += "('SHALLOW TRAVERSAL OF \"" + URL + "\"') ";
strQuery += @"WHERE ""DAV:isfolder"" = true";
strQuery += @"</g:sql>";
strQuery += @"</g:searchrequest>";
MyCredentialCache = new System.Net.CredentialCache();
MyCredentialCache.Add( new System.Uri(URL),
"NTLM",
new System.Net.NetworkCredential(userName, userPassword, userDomain)
);
Request = (System.Net.HttpWebRequest)HttpWebRequest.Create(URL);
Request.Credentials = MyCredentialCache;
Request.Method = "SEARCH";
bytes = Encoding.UTF8.GetBytes((string)strQuery);
Request.ContentLength = bytes.Length;
RequestStream = Request.GetRequestStream();
RequestStream.Write(bytes, 0, bytes.Length);
RequestStream.Close();
Request.ContentType = "text/xml";
Request.Headers.Add("Translate", "f");
Request.Headers.Add("Depth", "0");
Response = (HttpWebResponse)Request.GetResponse();
ResponseStream = Response.GetResponseStream();
ResponseXmlDoc = new XmlDocument();
ResponseXmlDoc.Load(ResponseStream);
// Get the XML nodes that contain the individual sizes.
oXMLSizeNodes = ResponseXmlDoc.GetElementsByTagName("d:x0e080003");
oXMLHREFNodes = ResponseXmlDoc.GetElementsByTagName("a:href");
oXMLHasSubsNodes = ResponseXmlDoc.GetElementsByTagName("a:hassubs");
// Loop through the nodes, and then add all of the sizes.
for (int i=0; i < oXMLSizeNodes.Count; i++)
{
totalSize += long.Parse(oXMLSizeNodes.Item(i).InnerText);
if (oXMLHasSubsNodes.Item(i).InnerText == "1")
{
totalSize += FolderSize(oXMLHREFNodes.Item(i).InnerText, userName, userPassword, userDomain);
}
}
ResponseStream.Close();
Response.Close();
return totalSize;
}
catch(Exception ex)
{
Console.WriteLine(ex.Message);
return 0;
}
}
}
}
Ensuite, voici le code de l'appelant:
[STAThread]
static void Main(string[] args)
{
long totalSizeO;
double totalSizeKO;
string userName = "exchangesuperuser";
totalSizeO = WebDAVSize.FolderSize("http://davrous2005/exchange/" + userName + "/NON_IPM_SUBTREE", "exchangesuperuser", "password!1", "DAVROUS2K3");
Console.WriteLine ("******************************************");
Console.WriteLine ("* TOTAL FINAL SIZE : " + totalSizeO + " Octets");
totalSizeKO = totalSizeO/(double)1024;
totalSizeKO = Math.Ceiling(totalSizeKO);
Console.WriteLine ("* TOTAL FINAL SIZE : " + totalSizeKO + " KO");
Console.WriteLine ("******************************************");
Console.ReadLine();
}
Pour terminer, voici le résultalt sur le serveur Exchange 2003 vu plus haut:
Le résultat est bien identique.
