C#实现json xml与实体类互相转换

首先是json与实体类之间的的转换，现有如下json数据：

{"Content": "中午12点开会","ResultCode": "502","Sign": "签名","Names": ["赵小美", "莉莎", "林妹妹"]}

根据json数据定义实体类：

public class JsonRoot{public string Content {get; set; }public string ResultCode {get; set; }public string Sign {get; set; }public List<string> Names {get; set; }}

转换操作：

public JsonRoot JsonToEntityClass(){string js = "{\"Content\":\"中午12点开会\",\"ResultCode\":\"502\",\"Sign\":\"签名\",\"Names\":[\"赵小美\",\"莉莎\",\"林妹妹\"]}";return JsonConvert.DeserializeObject<JsonRoot>(js);}

同样将实体类转换为json如下：

public string EntityClassToJson(){JsonRoot jr = new JsonRoot(){Content = "中午12点开会",ResultCode = "502",Sign = "签名",Names = new List<string>() {"赵小美","莉莎","林妹妹" }};return JsonConvert.SerializeObject(jr);}

下面是xml与实体类的转换，有如下xml：

<ROOT><SCHOOL_ID>S00001</SCHOOL_ID><SCHOOL_NAME>清华大学</SCHOOL_NAME><GRADE><GRADE_NAME>1年级</GRADE_NAME><GRADE_ID></GRADE_ID><STUDENT_NUMBER>0</STUDENT_NUMBER><MAJOR><MAJOR_NAME>软件工程</MAJOR_NAME><MAJOR_ID>1003</MAJOR_ID></MAJOR><MAJOR><MAJOR_NAME>软件工程</MAJOR_NAME><MAJOR_ID></MAJOR_ID></MAJOR></GRADE><GRADE><GRADE_NAME>2年级</GRADE_NAME><GRADE_ID>3008</GRADE_ID><STUDENT_NUMBER>200</STUDENT_NUMBER><MAJOR><MAJOR_NAME>软件工程</MAJOR_NAME><MAJOR_ID>1003</MAJOR_ID></MAJOR><MAJOR><MAJOR_NAME>软件工程</MAJOR_NAME><MAJOR_ID></MAJOR_ID></MAJOR></GRADE></ROOT>

首先是xml转实体类，实体类定义如下：

[System.Serializable()][ponentModel.DesignerCategory("code")][System.Xml.Serialization.XmlType(AnonymousType = true)][System.Xml.Serialization.XmlRoot(Namespace = "", IsNullable = false)]public partial class ROOT{public string SCHOOL_ID {get; set; }public string SCHOOL_NAME {get; set; }[System.Xml.Serialization.XmlElement("GRADE")]public List<GRADE> GRADE {get; set; }}[System.Serializable()][ponentModel.DesignerCategory("code")][System.Xml.Serialization.XmlType(AnonymousType = true)]public partial class GRADE{public string GRADE_NAME {get; set; }public string GRADE_ID {get; set; }public string STUDENT_NUMBER {get; set; }[System.Xml.Serialization.XmlElement("MAJOR")]public List<MAJOR> MAJOR {get; set; }}[System.Serializable()][ponentModel.DesignerCategory("code")][System.Xml.Serialization.XmlType(AnonymousType = true)]public partial class MAJOR{public string MAJOR_NAME {get; set; }public string MAJOR_ID {get; set; }}

xml转实体类如下操作：

public ROOT XMlToEntityClass(){ROOT ec = new ROOT();string xml = "<ROOT><SCHOOL_ID>S00001</SCHOOL_ID><SCHOOL_NAME>清华大学</SCHOOL_NAME><GRADE><GRADE_NAME>1年级</GRADE_NAME><GRADE_ID></GRADE_ID><STUDENT_NUMBER>0</STUDENT_NUMBER><MAJOR><MAJOR_NAME>软件工程</MAJOR_NAME><MAJOR_ID>1003</MAJOR_ID></MAJOR><MAJOR><MAJOR_NAME>软件工程</MAJOR_NAME><MAJOR_ID></MAJOR_ID></MAJOR></GRADE><GRADE><GRADE_NAME>2年级</GRADE_NAME><GRADE_ID>3008</GRADE_ID><STUDENT_NUMBER>200</STUDENT_NUMBER><MAJOR><MAJOR_NAME>软件工程</MAJOR_NAME><MAJOR_ID>1003</MAJOR_ID></MAJOR><MAJOR><MAJOR_NAME>软件工程</MAJOR_NAME><MAJOR_ID></MAJOR_ID></MAJOR></GRADE></ROOT>";using (StringReader sr = new StringReader(xml)){XmlSerializer serializer = new XmlSerializer(typeof(ROOT));ec = serializer.Deserialize(sr) as ROOT;}return ec;}

同样由实体类生成xml：

public string EntityClassToXml(){List<GRADE> lsMst = new List<GRADE>();for (int i = 0; i < 2; i++){List<MAJOR> lsDtl = new List<MAJOR>();for (int j = 0; j < 2; j++){MAJOR dtl = new MAJOR{MAJOR_NAME = "软件工程",MAJOR_ID = j+1+"003"};lsDtl.Add(dtl);}GRADE mst = new GRADE{GRADE_NAME = i + 1 + "年级",GRADE_ID = i + 2 + "008",STUDENT_NUMBER = (i * 200).ToString(),MAJOR = lsDtl};lsMst.Add(mst);}ROOT root = new ROOT{SCHOOL_ID = "S00001",SCHOOL_NAME = "清华大学",GRADE = lsMst};string s1 = string.Empty;using (StringWriter sw = new StringWriter()){XmlSerializer serializer = new XmlSerializer(root.GetType());serializer.Serialize(sw, root);sw.Close();s1 = sw.ToString();}XmlDocument doc = new XmlDocument();doc.LoadXml(s1);//移除首节点XmlNode xmlNode = doc.FirstChild;doc.RemoveChild(xmlNode);//移除ROOT属性XmlElement node = (XmlElement)doc.SelectSingleNode("ROOT");node.RemoveAllAttributes();s1 = doc.InnerXml;return s1;}
