爲什麼我的WebService調用僅對一個用戶失敗？

Question

我有一個簡單的WebService方法，將數據庫結果作爲DataSet返回。

這種方法失敗了該公司一個用戶，但適用於其他人 這裏是崩潰：

客戶端是一個.NET WinForms應用程序 我已經驗證的web服務的方法產生XML正確 只是似乎反序列化失敗

難道是因爲她運行.Net Framework 4和應用程序是爲3.5？

Answer 1

Exception:FormatException Message:Input string was not in a correct format

是文化在用戶的機器上一樣，其正在工作的其他人呢？只是一個想法，因爲它可能使用不同的文化，因此使用不同的IFormatProvider

Answer 2

看看你的堆棧跟蹤的中間...

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) 

好像從字符串解析錯誤INT ....我建議你嘗試和研究這個領域。
