You need to try the code. No one put the perfect code for your case may be they put something like "mymethod" or my "Param". Any way, you can use this:

String fileToUpload = @"C:\YourFile.txt";
        String sharePointSite = "http://yoursite.com/sites/Research/";
        String documentLibraryName = "Shared Documents";

        using (SPSite oSite = new SPSite(sharePointSite))
        {
            using (SPWeb oWeb = oSite.OpenWeb())
            {
                if (!System.IO.File.Exists(fileToUpload))
                    throw new FileNotFoundException("File not found.", fileToUpload);                    

                SPFolder myLibrary = oWeb.Folders[documentLibraryName];

                // Prepare to upload
                Boolean replaceExistingFiles = true;
                String fileName = System.IO.Path.GetFileName(fileToUpload);
                FileStream fileStream = File.OpenRead(fileToUpload);

                // Upload document
                SPFile spfile = myLibrary.Files.Add(fileName, fileStream, replaceExistingFiles);

                // Commit 
                myLibrary.Update();
            }
        }
