ToDouble() - problem

[Guest]

This should be simple, but either I'm blind, stupid or going mad.

I'm trying to convert a string, containing a numeric value to a double (in
C#), but when I run the code below I get the error message "Input string was
not in a correct format." Why?

string s = "8.0";
double d = Convert.ToDouble(s);

Hi,

No reason to fail. Check your decimal symbol entry on the regional
settings/control panel. But it should parse it in anyway.
Finally you can try to use a formatprovider to assign the dot as a decimal
seperator.

Good Luck

Hi,

It does not fail.

The only reason I can think of is about your locale , take a look at this
overload of ToDouble()

Please see my response in one of the other newsgroups you posted to.
It's generally not a good idea to post to multiple newsgroups,
precisely for this reason. See
