WCF不允许大列表.远程服务器返回了一个意外的响应:(400)错误的请求."例外
本文关键字：响应 不允许 错误 请求 例外 quot 意外 一个 返回 服务器 WCF | 更新日期: 2023-09-27 18:09:42
我有一个有9个字段的列表。当我通过一个较小的列表(说50行)，应用程序工作正常。如果我传递一个更大的列表，我的服务抛出异常"远程服务器返回了一个意外的响应:(400)错误的请求。"异常。请帮我解决这个问题。
我的Web配置如下

我猜我显式定义的端点和绑定没有被服务使用。如果我配置了错误的服务，请纠正我
试试下面的标签
您的应用程序中的问题是您为服务使用了不同的契约名称。在网络上。配置您使用的合同名称为"ServiceReference1"。在service web配置中，您使用的合同名称为"service .IService1"。也许这会解决你的问题。
