How do I upload a file to a folder using webdav?

I have this webdav code that creates folders in SharePoint:

HttpWebRequest request = (System.Net.HttpWebRequest)HttpWebRequest.Create(folderAddress);
                request.Credentials = wsLists.Credentials; // CredentialCache.DefaultCredentials;
                request.Method = "MKCOL";
                response = (System.Net.HttpWebResponse)request.GetResponse();
                response.Close();

      

        
        
        
      

    

How do I now change the code to download the file to this newly created folder. I think this is a general webdav question, thanks
