字符串加倍 [英] string to double

问题描述

我在vb.net 2005中创建了一个应用程序。它在我的机器上工作正常。我测试了几台不同的测试机，一切正常。至于客户端，它正在产生错误。我的应用程序从excel表读取并将值导入oracle数据库。生成的错误是：从类型字符串转换为类型double无效。为什么它只在客户端的计算机上而不是我的计算机上生成？

I created an application in vb.net 2005. It works fine on my machine. I tested several different test machines and all were working fine. As for the client, it''s generating an error. My application reads from an excel sheet and imports the values to an oracle database. the error being generated is: "conversion from type string to type double is not valid". Why is it generating only on the client''s computer and not mine?

您可以发布执行此操作的代码吗？

@dandalero
Can you post the code that does this?

Steven

Dim deci As Decimal = 0

deci = CDec （dt.Rows（i）.Item（13））


如果不是IsDBNull（dt.Rows（i）.Item（13））AndAso deci> 0然后

.price = CDec（dt.Rows（i）.Item（13））

结束如果


POITEM .price = .price

Dim deci As Decimal = 0
deci = CDec(dt.Rows(i).Item(13))

If Not IsDBNull(dt.Rows(i).Item(13)) AndAlso deci > 0 Then
.price = CDec(dt.Rows(i).Item(13))
End If

POITEM.price = .price

它是否与机器上的区域设置有关？这通常会在例如0,13和0.13。


Steven

Could it have something to do with the regional settings on the machines? This often creates a difference between e.g. 0,13 and 0.13.
