Question

我有一个使用WCF服务的Web应用程序。我正在尝试通过此WCF服务更新存储在云中的数据库中的某些内容，但我收到此错误：

远程服务器返回了意外响应：（400）

我认为无论maxRequestLenght和其他参数有多大，我都会得到StackOverFlow。

以下是一些代码：

更新条目的WCF方法：

  public void updateMember(Membership member)
    {
        _context.Memberships.ApplyCurrentValues(member);
        _context.SaveChanges();     
    }

我使用WCF服务的编辑方法：

 [HttpPost]
    public ActionResult Edit(Membership member)
    {
        Guid guid = AcsPrincipal.getGuid();
        Membership model = client.getMember(guid);
        model.Bikes = member.Bikes;
        model.City = member.City;
        model.Comment = member.Comment;
        model.Country = member.Country;
        model.Age = member.Age;
        if (ModelState.IsValid)
        {

            client.updateMember(model);
            return RedirectToAction("Details");
        }
        return View(model);
    }

我被困在这里几天......

非常感谢！

稍后编辑 WCF web.config

Answer 1

好的，2天后我发现了！

问题是：

_context.Memberships.ApplyCurrentValues（构件）;

现在我正在更新模型，只是在WCF中保存更改。
