图片上传在服务器中不起作用。在本地主机上工作正常

Question

所以，这段代码在本地主机上工作得很好。它删除以前的图像并上传新图像。但是它在服务器上什么也不做。有什么线索吗？

我已经使用 AJAX 进行异步调用顺便说一下，如果这有什么不同的话。

  var db=Database.Open("StarterSite");
  var contentQuery="Select * from Contents where id =@0";
  var content=db.QuerySingle(contentQuery,"1");
  var message="";
  var imgCount=0;
  var alreadyExist=false;

    try{
      if (IsPost && Request.Files.Count > 0) {
            bool deleteSuccess = false;
            var fileName = "";
            var photoName = "";
            var fileSavePath = "";
            var uploadedFile = Request.Files[0];
            var toDelete=Request["toDelete"];
            var toUpload=Request["toUpload"];

            if(uploadedFile.ContentLength>0){
                 @******************DELETE***************@
                    var fullPath = Server.MapPath("~/img/" + toDelete);
                    if (File.Exists(fullPath))
                        {
                                File.Delete(fullPath);
                                deleteSuccess = true;
                        }
            @****************UPLOAD*******************@
                  fileName = Path.GetFileName(uploadedFile.FileName);
                    fileSavePath = Server.MapPath("~/img/" +
                      fileName);
                    uploadedFile.SaveAs(fileSavePath);
                    var updateQuery="Update Contents Set "+toUpload +"=@0";
                    db.Execute(updateQuery, fileName);
                    //Response.Redirect("editMode.cshtml");
          }
       }
    }
    catch(HttpException ex){
      message="Image size you selected was too large. Please select a different Image.";
    }
