There may arise cases when you want to performs upload and delete documents to and from SharePoint document libraries using C# but you don’t have or want to involve SharePoint dlls to perform this action.

These can be used in tandem to achieve the required goal.

 

//

// Upload document to SharePoint library

//

 

System.Net.WebClient sharePointLibrary = new System.Net.WebClient();

sharePointLibrary.Credentials = new System.Net.NetworkCredential(“SharePointUser“,”SharePointUserPassword“);

byte[] response = sharePointLibrary.UploadFile(Path.Combine(“SharePointURI“, “ResultantFileName“), “PUT“, Path.Combine(“TestLocationofFileToUpload“, “NameOfTheFileToBeUploaded“));

 

//

// Delete document from SharePoint library

//

 

var request = (System.Net.HttpWebRequest)System.Net.WebRequest.Create(“FullSharePointURIofDocument“);

request.Timeout = System.Threading.Timeout.Infinite;

request.Credentials = new System.Net.NetworkCredential(“SharePointUser“,”SharePointUserPassword“);
