Converting Double to String with desired decimal separator
提问by Wine Too
I have to convert number (double) to string like this:
我必须像这样将数字（双）转换为字符串：
Dim myDouble = 3.14
Dim myDoubleStr = myDouble.ToString ''OR myDouble.ToString("N")
According to my 'culture' settings result is "3,14" what is in most cases OK. But here are cases that I need string representation of a number with decimal point instead of comma. In that case I replace char "," with "." like string manipulation.
根据我的“文化”设置结果是“3,14”，在大多数情况下是可以的。但在某些情况下，我需要用小数点而不是逗号来表示数字的字符串。在这种情况下，我将字符“，”替换为“。” 像字符串操作。
Is here a way that "ToString" convert a number with decimal point directly when this is needed?
这是一种“ToString”在需要时直接转换带小数点的数字的方法吗？

You can also have as much precession as you want by specifying the format like this:
您还可以通过指定如下格式来获得尽可能多的进动：
Dim myDouble As Double = 3.14159268
Dim myDoubleStr = myDouble.ToString("0.00000") 'The value will be 3.14159
In case you wanted to use Thousands separator, use this format:
如果您想使用千位分隔符，请使用以下格式：
Dim myDouble = 961327.1234567890
Dim MyDoubleStr = myDouble.ToString("#,##0.00000")
'The value of MyDoubleStr will be 961,327.12345
