实体对象转换成json字符串
原理很简单,用反射获返回实体的属性的数组
循环输出属性名和值,拼接Json格式字符串返回(转义掉 '\','"'影响Json格式的字符)
\ -> \\
" -> \"
using System.Reflection;
/// <summary> /// /// </summary> /// <param name="obj">要转换的实体对象</param> /// <returns></returns> public string EntityToJson(object obj) { StringBuilder jsonStr = new StringBuilder(); PropertyInfo[] pInfos = obj.GetType().GetProperties(); string pValue = string.Empty; jsonStr.Append("{"); foreach (PropertyInfo p in pInfos) { if (!(p.GetValue(obj, null) == null)) { //转义掉Json格式特殊字符 ‘\’,‘"’ pValue = p.GetValue(obj, null).ToString().Replace("\\", "\\\\").Replace("\"", "\\\""); } else { pValue = string.Empty; } jsonStr.Append(string.Format("\"{0}\":\"{1}\",", p.Name, pValue)); } jsonStr.Remove(jsonStr.Length - 1, 1); jsonStr.Append("}"); return jsonStr.ToString(); }
