判断字符串是否是数字标点空白

static void Main(string[] args) { Console.WriteLine("*********"); CharFunctionality(); Console.ReadLine(); } private static void CharFunctionality() { char myChar = 'a'; //是否是数字 Console.WriteLine("char.IsDigit('a'):{0}", char.IsDigit(myChar)); //是否是字母 Console.WriteLine("char.isletter('a');{0}", char.IsLetter(myChar)); //是否unicode是否为空 Console.WriteLine("char iswithspace('hello there',5);{0}", char.IsWhiteSpace("hello there", 5)); Console.WriteLine("char iswithspace('hello there',6);{0}", char.IsWhiteSpace("hello there", 6)); //是都是标点符号 Console.WriteLine("char.ispunctuation('?'):{0}", char.IsPunctuation('?')); }
