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
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
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
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 (); 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key10 parameters1.Add("dtype", ""); //返回数据的格式,xml或json，默认json11 12 string result2 = SendPost(url1, parameters1, "get");13 14 var hanziRequestResponse = JsonConvert.DeserializeObject (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：
1 [DataContract] 2 public class HanziRequestResponse 3 { 4 [DataMember(Name = "reason")] 5 public string Reason { get; set; } 6 7 [DataMember(Name = "error_code")] 8 public string ErrorCode { get; set; } 9 10 [DataMember(Name = "result")]11 public HanziDetail Result { get; set; }12 }13 [DataContract]14 public class HanziDetail15 {16 [DataMember(Name = "zi")]17 public string Hanzi { get; set; }18 19 /// 20 /// 部首21 /// 22 [DataMember(Name = "bushou")]23 public string Radical { get; set; }24 25 /// 26 /// 拼音27 /// 28 [DataMember(Name = "pinyin")]29 public string Pinyin { get; set; }30 31 /// 32 /// 笔画数33 /// 34 [DataMember(Name = "bihua")]35 public string Bihua { get; set; }36 37 /// 38 /// 五笔39 /// 40 [DataMember(Name = "wubi")]41 public string WuBi { get; set; }42 43 /// 44 /// 极简介绍45 /// 46 [DataMember(Name = "jijie")]47 public List SimpleDetailContent { get; set; }48 } 访问后台接口通用类：
