示例1: Main
//引入命名空間
using System;
public class CharStructureSample
{
public static void Main()
{
char chA = 'A';
char ch1 = '1';
string str = "test string";
Console.WriteLine(chA.CompareTo('B')); //----------- Output: "-1" (meaning 'A' is 1 less than 'B')
Console.WriteLine(chA.Equals('A')); //----------- Output: "True"
Console.WriteLine(Char.GetNumericValue(ch1)); //----------- Output: "1"
Console.WriteLine(Char.IsControl('\t')); //----------- Output: "True"
Console.WriteLine(Char.IsDigit(ch1)); //----------- Output: "True"
Console.WriteLine(Char.IsLetter(',')); //----------- Output: "False"
Console.WriteLine(Char.IsLower('u')); //----------- Output: "True"
Console.WriteLine(Char.IsNumber(ch1)); //----------- Output: "True"
Console.WriteLine(Char.IsPunctuation('.')); //----------- Output: "True"
Console.WriteLine(Char.IsSeparator(str, 4)); //----------- Output: "True"
Console.WriteLine(Char.IsSymbol('+')); //----------- Output: "True"
Console.WriteLine(Char.IsWhiteSpace(str, 4)); //----------- Output: "True"
Console.WriteLine(Char.Parse("S")); //----------- Output: "S"
Console.WriteLine(Char.ToLower('M')); //----------- Output: "m"
Console.WriteLine('x'.ToString()); //----------- Output: "x"
