我现在完全被这个问题难住了。过去两天我一直在阅读各种文章和博客，并做出了大部分建议的更改，但我仍然遇到这个问题。

基本上我将一个数组对象作为参数从客户端传递给服务，然后给我上面的错误。

我可以处理 200 条记录，但如果我将其设置为 250，例如，它会返回 400 错误。我已经启用了跟踪等，但是当它出错时根本没有记录任何内容。客户端和服务都在相同的环境中运行（测试目的）-windows 2008r2 我将展示两个配置文件以及我如何调用服务。

客户端配置

以下是我在客户端中调用此服务的方式...

List<FUMStruct> fList = new List<FUMStruct>();

for (int i = 0; i < 250; i++)
{
    var t = new FUMStruct();
    t.clientID = "1234";
    t.ClientCRMGUID = new Guid("9EACA7AE-FE7E-E211-956A-00505622E202");
    t.CRMAccountCRMGUID = new Guid("A63D9ADC-0CFF-E211-94E9-00505622E202");
    t.Balance = 200 + i;
    fList.Add(t);
}
var serv = new FinHqclientClient();            
serv.UpdateLastFUMGUID(fList.ToArray());

这是因为绑定中有一个“名称”值。因此，我们设置的自定义值没有被应用，它正在加载服务器默认值（甚至不确定不同绑定的“默认值”保存在哪里！）我在网上阅读的一篇文章中发现了这一点并制作了一个新的仅使用基本绑定的服务..一直失败，直到我删除了名称然后它开始工作！然后我必须弄清楚如何为 wsHttpBinding 执行此操作，因为使用该绑定，如果您不指定名称（然后显然您无法引用配置），您会遇到各种或安全问题等，并且服务不起作用..所以解决方案是添加另一个没有 name 属性的绑定。

最后只需要在服务器端进行这些设置，因为我保留了默认客户端值（低于上面示例中的值）并且它仍然有效。下面是完整的 web.config..注意我必须默认 basicHttpbinding 和 wsHttpbinding

我注意到您增加了客户端的 maxRequestLength，但没有增加服务器：

  <system.web>
    <!-- ... -->
    <httpRuntime  executionTimeout="180" maxRequestLength="2147483647" />
  </system.web>

此配置选项实际上只与服务器相关，因为它设置了入站请求的允许大小。无论如何，我会将此部分添加到您的服务器配置文件中，看看是否可以解决问题。默认请求大小为 4MB，根据经验，我知道这可能会导致您报告的错误。
