经常会遇到系统数据交互采用JSON数据格式进行交互的，避免不必要的重复工作，记录下自己的处理方式。
获取数据集之后，通过函数对数据集信息进行整理通过.Net Framework3.5提出的JavaScriptSerializer类进行DataSet数据的序列化，
需要添加System.Web.Extensions引用：
private static string DataToJson(DataSet metaData,string msg) { DataTable resultInfo = new DataTable("success"); resultInfo.Columns.Add("RETURN_CODE", Type.GetType("System.String")); resultInfo.Columns.Add("ERROR_MSG", Type.GetType("System.String")); DataRow newRow = resultInfo.NewRow(); if (metaData == null || metaData.Tables.Count <= 0 || metaData.Tables[0].Rows.Count <= 0) { newRow["RETURN_CODE"] = "-1"; if (string.IsNullOrEmpty(msg)) { newRow["ERROR_MSG"] = "查询结果为空"; } else { newRow["ERROR_MSG"] = msg; } resultInfo.Rows.Add(newRow); metaData.Tables.Add(resultInfo); } else { newRow["RETURN_CODE"] = "0"; newRow["ERROR_MSG"] = ""; resultInfo.Rows.Add(newRow); metaData.Tables.Add(resultInfo); } StringBuilder sb = new StringBuilder(); sb.Append("{"); JavaScriptSerializer serializer = new JavaScriptSerializer(); foreach (DataTable dt in metaData.Tables) { sb.Append(string.Format("\"{0}\":",dt.TableName)); ArrayList arrayList=new ArrayList(); foreach (DataRow dataRow in dt.Rows) { Dictionary<string, object> dictionary = new Dictionary<string, object>(); foreach (DataColumn dataColumn in dt.Columns) { dictionary.Add(dataColumn.ColumnName,dataRow[dataColumn.ColumnName]); } arrayList.Add(dictionary); } sb.Append(serializer.Serialize(arrayList)); sb.Append(","); } return sb.Remove(sb.Length - 1, 1).Append("}").ToString(); }
此时我们获取了一个JSON格式的字符串，在接收方同样可以通过JavaScriptSerializer将字符串转换为自己需要的数据格式如ArrayList：
private ArrayList JsonToList(string json) { JavaScriptSerializer serializer = new JavaScriptSerializer(); Dictionary<string,object> dictionary= serializer.Deserialize<Dictionary<string,object>>(json); return (ArrayList)dictionary["data"]; }
也可以将JSON转换为对象：
internal bool ValidateWebJsonValues(ref UserInfo userInfo, string userName, string passWord) { try { string json = "{"data":{"accounts":null,"delFlag":"0","email":null,"emailState":null,"instOrgId":null,"institue":false,"member":false,"mobile":null,"org":false,"realName":"包文强","state":"0","teacher":true,"userId":121438653944262,"userType":"2"},"success":true}"; JavaScriptSerializer jsSerializer = new JavaScriptSerializer(); Dictionary<string, object> dic = jsSerializer.Deserialize<Dictionary<string, object>>(json); bool dataResult = (bool)dic["success"]; if (dataResult) { Dictionary<string, object> dataDic = (Dictionary<string, object>)dic["data"]; Type type = typeof(UserInfo); PropertyInfo[] propInfo = type.GetProperties(); foreach (PropertyInfo prop in propInfo) { if (dataDic[prop.Name] != null) { prop.SetValue(userInfo, dataDic[prop.Name], null); } else { prop.SetValue(userInfo, "", null); } } } return dataResult; } catch (Exception ex) { return false; } }
以上代码是根据个人过往处理这方面问题的代码进行简单调整，也涉及到一些判断逻辑。作为参考，可以修改调整后使用。
