问题描述

请为我提供一些示例代码，这些代码将清楚地突出显示差异.

Hi,
What is the difference between Char.IsDigit() and Char.IsNumber in C#.
I got the theoretical difference on MSDN.
Kindly provide me some sample code that will highlight the difference clearly.

推荐答案

MSDN确实非常清楚地说明了这一点. IsDigit仅适用于0-9. IsNumber允许其他数字值，例如小数.

MSDN does spell it out very clearly. IsDigit only works with 0-9. IsNumber allows other number values such as fractions.

string numbers = "0123456789¼½¾";
for (int i = 0; i < numbers.Length; i++)
    {
    char c = numbers[i];
    Console.WriteLine("{0}: IsNumber({1}), IsDigit({2})", c, Char.IsNumber(c), Char.IsDigit(c));
    }
