Fazer Download de documentos do Sharepoint 2003 usando WS nativos e sem usar OM

Olá Amigos,

Abaixo um pequeno código, que demotra como podemos baixar documentos de uma document library do SharePoint 2003.



public void DownloadFilesFromDocumentLibrary(string url, string documentLibraryName){
Lists.Lists proxy = new Lists.Lists();//set url and credentials on proxy
proxy.Url = url + "_vti_bin/lists.asmx";
proxy.Credentials = CredentialCache.DefaultCredentials;//call get list items to retrieve document library
XmlNode elm = proxy.GetListItems(documentLibraryName, null, null, null, null, null);
XmlNamespaceManager nsMgr = new XmlNamespaceManager(elm.OwnerDocument.NameTable);
nsMgr.AddNamespace("rs", "urn:schemas-microsoft-com:rowset");
nsMgr.AddNamespace("z", "#RowsetSchema");
if (elm != null){
XmlNode dataNode = elm.SelectSingleNode("rs:data", nsMgr);
int itemCount = Convert.ToInt32(dataNode.Attributes.GetNamedItem("ItemCount").Value);
if (itemCount == 0){
Console.WriteLine("Nothing to download");
}else{
foreach (XmlNode row in dataNode.SelectNodes("z:row", nsMgr))
{
//Response.Write(row.Attributes.GetNamedItem("ows_LinkFilename").Value+"
");
DownLoadFile(url, documentLibraryName, row.Attributes.GetNamedItem("ows_LinkFilename").Value);
}
}
}
}



public void DownLoadFile(string url, string documentLibraryName, string fileName){
//string downloadPage = url + "/download.aspx";
HttpWebRequest request = null;
HttpWebResponse response = null;
Stream responseStream = null;
FileStream fs = null;
try{
//request = (HttpWebRequest) HttpWebRequest.Create(downloadPage + "?SourceUrl=" + documentLibraryName + "/" + fileName);
request = (HttpWebRequest)HttpWebRequest.Create(SharePointHost + documentLibraryName + "/" + fileName);
request.Credentials = CredentialCache.DefaultCredentials;
request.Timeout = 6000;
response = (HttpWebResponse)request.GetResponse();
responseStream = response.GetResponseStream();//write to filesystem
fs = new FileStream(fileName, FileMode.Create);
byte[] buffer = new byte[1024];
int count = responseStream.Read(buffer, 0, buffer.Length);
while (count > 0)
{
fs.Write(buffer, 0, buffer.Length);
count = responseStream.Read(buffer, 0, buffer.Length);
}
}
finally{
if(fs != null)
fs.Close();
if(responseStream != null)
responseStream.Close();
if(response!=null)
response.Close();
}
}
