SharePoint File Upload

For some little functionality, I wanted to do a file upload to a document library by some custom .NET only code:


ListsSoapClient client = new ListsSoapClient();
XElement result = client.GetListItems("{642DF480-74CB-4EDC-865C-CA009054998F}", null, null, null, null, null, null);
XNamespace rs = "urn:schemas-microsoft-com:rowset";
XNamespace z = "#RowsetSchema";
var data = result.Descendants(rs + "data").Descendants(z+"row");

CopySoapClient copyClient = new CopySoapClient();
FieldInformation[] fields;
byte[] output;
uint result2 = copyClient.GetItem(Uri.EscapeUriString("http://example.hostname/"+"Documents/Report.xls"), out fields, out output);

string destinationUrl = "http://example.hostname/Documents/Test.xls";
string[] destinationUrls = { Uri.EscapeUriString(destinationUrl) };
List<fieldinformation> fieldsList = new List<fieldinformation>();

CopyResult[] copyResults;

uint result3 = copyClient.CopyIntoItems("+", destinationUrls, fieldsList.ToArray(), output, out copyResults);
WebRequest request = WebRequest.Create(destinationUrl);
request.Method = "PUT";
request.Credentials = CredentialCache.DefaultCredentials;
// Write the contents of the local file to the request stream.
using (Stream stream = request.GetRequestStream())
{
//Load the content from local file to stream
stream.Write(output, 0, output.Length);
}
WebResponse response = request.GetResponse();
response.Close();
