如何获取全部汉字及汉字的详细信息？
刚刚扒了一通汉字完整的数据字典，mark作下记录。
所有汉字集合
我们匹配中文字符时，经常使用Unicode字符"[^\u4e00-\u9fa5]"正则表达式来校验。
详细的汉字字符集列表可参考：
具体的汉字对应的字符，可查询汉字字符集编码查询网站
基本汉字中从4e00到9fa5，十六进制转化为十进制后，可知共有20902个汉字。
汉字的集合，是开源的，可以直接从网上获取。
从以上链接中，下载汉字集合
获取汉字信息
汉字的详细信息，包括拼音/笔画数/部首/五笔输入/笔顺编号/注解
网上有相应的新华字典Api接口，这里选的是聚合平台-新华字典
通过他的C#源码,我们可以获取到汉字字典的详细信息
详细数据请点击 下载
PS:
- 部首和五笔可能为空，部首返回的数据为："难检字"。
- 笔顺编号可通过返回的简解中得到。笔顺编号，即指每个笔画对应的号码，这个非常有用！
聚合接口-汉字
获取汉字：
1 public static HanziDetail FindHanzi(string hanzi)
2 {
3 //1.根据汉字查询字典
4 string url1 = "http://v.juhe.cn/xhzd/query";
5
6 var parameters1 = new Dictionary<string, string>();
7
8 parameters1.Add("word", hanzi); //填写需要查询的汉字，UTF8 urlencode编码
9 parameters1.Add("key", "XXXXXX");//你申请的key
10 parameters1.Add("dtype", ""); //返回数据的格式,xml或json，默认json
11
12 string result2 = SendPost(url1, parameters1, "get");
13
14 var hanziRequestResponse = JsonConvert.DeserializeObject<HanziRequestResponse>(result2);
15
16 //HanziDetail hanziDetail = null;
17 //if (hanziRequestResponse.ErrorCode == "0" && hanziRequestResponse.Result != null)
18 //{
19 // hanziDetail = hanziRequestResponse.Result;
20 //}
21
22 return hanziRequestResponse.Result;
23 }
24 }
解析类：

10 [DataMember(Name = "result")]
11 public HanziDetail Result { get; set; }
