Simple Json Lib.

I went looking for Json. But there wasn't a simple Json.
I just wanted to change  Class to Json and change Class back to Json. So I made it myself. zJson.cs 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 125 126 127 128 129 130 131 132 133 134 135 136 137 138 139 140 141 142 143 144 145 146 147 148 149 150 151 152 153 154 155 156 157 158 159 160 161 162 163 164 165 166 167 168 169 170 171 172 173 174 175 176 177 178 179 180 181 182 183 184 185 186 187 188 189 190 191 192 193 194 195 196 197 198 199 200 201 202 203 204 205 206 207 208 209 210 211 212 213 214 215 216 217 218 219 220 /* code by eekdro@gmail.com */ /* zJson is a simple Json library */ /* Just Class to Json, Json to Class, Haven't Depth*/     using System;

약간 이해가 안되는 내용이 있다면 나는 Datetime 을 Tick로 보관한다.
이유는 단순하다. 다국적 처리를 할때 Datetime를 String로 바꾸면 문제가 생길 수 있기 때문이다. If there is something special code, I use Tick to keep Datetime.
The reason is simple. Because changing Datetime to String can cause problem when dealing with multinational process. Test Code 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 using System; using System.Collections.Generic; using System.Text; using AliceUtil;   namespace JsonTest {     class Person     {         public bool ok;         public int Id;         public string Name;         public DateTime Ddate;         public int[] intArray = { 1, 2, 3, 4 };         public string[] strArray = { "1", "2", "3", "4" };     }         class Program     {         static void Main(string[] args)         {             List<Person> tbPerson = new List<Person>();               for (int n = 0; n < 3; n++)             {                 tbPerson.Add(                     zJson.Paser<Person>(("{'Id' : " + n + ", 'Name' : 'Alex', 'ok':true}").Replace("'", "\""))                     );             }               string result = zJson.MakeJson<Person>(tbPerson);             Console.WriteLine(result);             Console.WriteLine("---------------");               List<Person> PList = zJson.PaserList<Person>(result);             foreach( Person ps in PList)             {                 Console.WriteLine(zJson.MakeJson(ps));                             }                      }     } }
