Question

由于内部错误，服务器无法处理请求。有关错误的更多信息，请打开 IncludeExceptionDetailInFaults（来自ServiceBehaviorAttribute 或者从服务器上的配置行为）来发送异常信息返回给客户端，或者按照开启跟踪 Microsoft .NET Framework SDK文档并检查服务器跟踪日志。

如果问题来自服务器或系统

，我不知道

这是我的堆栈跟踪

System.ServiceModel.FaultException was unhandled
  HResult=-2146233087
  Message=The server was unable to process the request due to an internal error.  For more information about the error, either turn on IncludeExceptionDetailInFaults (either from ServiceBehaviorAttribute or from the <serviceDebug> configuration behavior) on the server in order to send the exception information back to the client, or turn on tracing as per the Microsoft .NET Framework SDK documentation and inspect the server trace logs.

Answer 1

美好的一天，我的这个问题需要回答已经很多年了。

所以……这里的问题是 Web Api 似乎是 reconfigured（当时我是新手，我不知道如何检查 Web API 因为我只做不使用 Web API 的离线基本应用程序，现在我知道 API 是如何工作的，问题是 API 没有被老程序员正确配置（顺便说一下，我只在该公司重新编程应用程序),

问题原因：

datatype-mismatch：从 int 到 nvarchar 这是唯一的问题。我只更改了列的数据类型，问题就解决了。

当您的连接超时时，您还可以遇到另一件事。我也使用 Indexing 解决了这个问题。您可以将 IncludeExceptionDetailInFaults = false 更改为 true，以便您可以查看遇到的错误。

无法使用vb.net中的Web服务在服务器中上传我的数据
