推荐答案

试试这个：

Hi,

Try this:

double d = 12345.67;
string reversedStr = new string(d.ToString().Reverse().ToArray());
double reversedDouble;
if (double.TryParse(reversedStr, out reversedDouble))
{
    // now, reversedDouble is the reversed double
}
else
{
    // unable to reverse the double
}

希望这会有所帮助。

Hope this helps.

转换为字符串，反向并将其转换回double。要写反向功能，请点击此链接。 http://stackoverflow.com/questions/228038/best-way-to-reverse- a-string [ ^ ]

Convert to string, reverse and convert it back to double. To write reverse function follow this link. http://stackoverflow.com/questions/228038/best-way-to-reverse-a-string[^]

你好，



试试这个：

Hello,

Try this:

void Main()
{
    double d = 12345.67;
    Console.WriteLine("Reversed: {0}", ReverseNumber(d));
}

double ReverseNumber(double number)
{
    return double.Parse(ReverseString(number.ToString()));
}

string ReverseString( string s )
{
    char[] charArray = s.ToCharArray();
    Array.Reverse( charArray );
    return new string( charArray );
}
