Problem with Double::ToString(__,__)

[Keith]

Hello,
I have the following sequence of statements


double MyDouble1;
bool TryParseReturnValue;
String ^ a = gcnew String("123.456");
TryParseReturnValue = Double::TryParse(a,MyDouble1);
MyDouble1 += 1;
a = Double::ToString(MyDouble1,IFormatProvider); // <---- error here


I do not understand what I need to put into the line with the error in order
to make it work. It's clear that "IFormatProvider" is incorrect, but what
are the exact options. Can you help?

ToString is not a static member in the Double class. You have to call
MyDouble.ToString(..)
Also you have to specify the format string and culture-specific
formatting info.

see the documentation
http://msdn.microsoft.com/en-us/library/d8ztz0sa.aspx

For eg,

using System::Globalization;

double dbl = 25.693;

String^ specifier = gcnew String(L"G");
String^ str = dbl.ToString( specifier,
CultureInfo::InvariantCulture );
