  Hello experts,

  I am recently working with sharepoint client object model to upload file to sharepoint  server365.

  I have been stuck by the issue that one file uploading results two versions on sharepoint. Please reference to the following code piece.

  Any hint or answer is appreciated.Thanks in advance.

          public void SaveFile()

         {

             ClientContext ctx = new ClientContext ("url")

             File file;

              ....

              // Get file

              ....

             UpdateProperties(file.List,ctx);

              FileSaveBinaryInformation fsbi = new FileSaveBinaryInformation();
              fsbi.Content = Doc.GetBytes();
              file.CheckIn("comment", CheckInType.MinorCheckIn);

              // Save file
              //
              file.SaveBinary(fsbi);

  }

          private void UpdateProperties(ListItem item,ClientContext CTX)
          {
                     // Update other properties
                      FieldLookupValue fvalue = new FieldLookupValue();
                      CTX.Load(spitem.Tag);
                      CTX.ExecuteQuery();
                      fvalue.LookupId = spitem.Tag.Id;
                      item["Customer"] = fvalue;// Lookup field
                      item.Update();// must call Update method. Otherwise, it will not be updated on sharepoint. Why? 
                  }
              }
              item["FileLeafRef"] = this.tb_name.Text;
          }
