in B4i

j.Initialize("UploadSigin", Me)
j.PostString("http://192.168.1.180:8081/WebService/ExamUserUploadSigin.aspx",jsonstring)

in .net Server

  string vTitle = "";
  string vDesc = "";
  string FilePath = Server.MapPath("/file/1.txt");      

  if (!string.IsNullOrEmpty(Request.Form["title"]))
  {
    vTitle = Request.Form["title"];
  }
  if (!string.IsNullOrEmpty(Request.Form["description"]))
  {
    vDesc = Request.Form["description"];
  }
  
  HttpFileCollection MyFileCollection = Request.Files;
  if (MyFileCollection.Count > 0)
  {
    // Save the File
    MyFileCollection[0].SaveAs(FilePath);
  }

Maybe you need to set the content type.
It is also possible that the server fails to parse the huge json string that is created.
