为什么我的 WebService 调用仅对一名用户失败？

Question

我有一个简单的 WebService 方法，它将数据库结果作为数据集返回。

此方法对公司中的一名用户失败，但对其他所有人都有效 崩溃如下：

客户端是 .Net WinForms 应用程序 我已验证 Web 服务中的方法是否正确生成 XML 似乎反序列化失败了，

这是否是因为她运行的是 .Net Framework 4 并且该应用程序是为 3.5 构建的？

Answer 1

异常：FormatException 消息：输入字符串的格式不正确

用户计算机上的区域性与其他正在运行的计算机上的区域性相同吗？只是一个想法，因为它可能使用不同的文化，因此使用不同的 IFormatProvider

Answer 2

看看你的堆栈跟踪的中间......

at Cwc.WaterWorks.Console.frmMain.GetCustomer(String customerKey, Boolean afterCreate)

Exception:FormatException Message:Input string was not in a correct format. 
Source:     mscorlib TargetSite: StringToNumber 
StackTrace:    at System.Number.StringToNumber(String str, NumberStyles options, NumberBuffer& number, NumberFormatInfo info, Boolean parseDecimal)     
at System.Number.ParseInt32(String s, NumberStyles style, NumberFormatInfo info) 

似乎是从 String 到 Int 的解析错误......我建议你尝试调查这个区域。
