问题描述

我得到了：



mscorlib.dll中发生了'System.FormatException'类型未处理的异常


附加信息：输入字符串的格式不正确。


执行简单行：

有什么问题？

几乎可以肯定你使用的是错误的CultureInfo。尝试指定

CultureInfo.InvariantCulture进行解析 - 我怀疑它当前是

，假设。是一个千位分隔符而不是小数点。

zelyal，


适合我。你确定它是这行代码吗？

文化，或许？

I got :
An unhandled exception of type ''System.FormatException'' occurred in
mscorlib.dll

Additional information: Input string was not in a correct format.

at execution of simple line:
double v1 = Double.Parse ("7200.0");

What''s wrong?

Almost certainly you''re using the wrong CultureInfo. Try specifying
CultureInfo.InvariantCulture to parse in - I suspect it''s currently
assuming that "." is a thousands separator rather than a decimal point.

zelyal,

Works for me. Are you sure it is this line of code?
