Save File to Sharepoint

This code shows how to use c# to send a file to Sharpoint using the WCF REST Services. 

Create service reference

Add a service reference to the C# Windows form project. The URL is 

http://test.sharepoint.nterprise.net/servicetesting/_vti_bin/ListData.svc

Create a Sharepoint Gateway class

        public string SendByteArrayToSharepoint(Byte[] bytes, string fileName)

        {

            try

            {

                string sharepointUrl = (string)Settings.Default["SharepointUrl"];

                Stream fileStream = new MemoryStream(bytes);

                ServiceTestingDataContext context = new ServiceTestingDataContext(_sharepointUri);

                context.Credentials = System.Net.CredentialCache.DefaultNetworkCredentials;

                string slug = Path.Combine(@"/servicetesting/DropBox/", fileName);

                string contentType = NtfsUtilities.GetMimeFromByteArray(bytes);

                DropBoxItem dbi = new DropBoxItem()

                {

                    ContentType = contentType,

                    Name = Path.GetFileName(fileName),

                    Source = "source",

                    TargetSystem = "targetSystem",

                    Reference = "reference",

                    Notes = "notes",

                    OriginalFilename = Path.GetFileName(fileName),

                    Path = fileName

                };

                context.AddToDropBox(dbi);

                context.SetSaveStream(dbi, fileStream, true, contentType, slug);

                context.SaveChanges();

                //at this point, the document ID is NULL, as it was assigned on the server.

                //Calling context.LoadProperty(dbi, "DocumentID"); causes the dbi object to be refreshed

                context.LoadProperty(dbi, "DocumentID");

                return dbi.DocumentID;

            }

            catch (Exception ex)

            {

                throw;

            }

        }

Use the class

Read the file into a byte array. then call the method SendByteArrayToSharepoint:

string SharepointPDFUrl = WriteBytesToSharepoint(theByteArray, "fileName.pdf");
