將對象轉為json格式，C# Json 和對象的相互轉換

Json 和對象的相互轉換

    /// <summary>/// Json 和對象的相互轉換  ——需引用using Newtonsoft.Json;   即：Jsonnet.net...../// </summary>public static class JsonHelper{/// <summary>/// 把對象轉換為JSON字符串/// </summary>/// <param name="o">對象</param>/// <returns>JSON字符串</returns>public static string ObjectToJson(this object o){if (o == null) return null;return JsonConvert.SerializeObject(o);}/// <summary>/// 把Json文本轉為實體/// </summary>/// <typeparam name="T"></typeparam>/// <param name="input"></param>/// <returns></returns>public static T JsonToObject<T>(this string input){try{return JsonConvert.DeserializeObject<T>(input);}catch (Exception ex){return default(T);}}}

使用如下所示：

  private void btnObjToJson_Click(object sender, EventArgs e){List<Test> timePart = new List<Test>();timePart.Add(new Test { BeginTime = 8.10, EndTime = 8.15 });timePart.Add(new Test { BeginTime = 8.15, EndTime = 8.25 });timePart.Add(new Test { BeginTime = 8.26, EndTime = 8.55 });string json = JsonHelper.ObjectToJson(timePart);MessageBox.Show("json\r\n==" + json);}private void btnJsonToObj_Click(object sender, EventArgs e){List<Test> timePart = new List<Test>();timePart.Add(new Test { BeginTime = 8.10, EndTime = 8.15 });timePart.Add(new Test { BeginTime = 8.15, EndTime = 8.25 });timePart.Add(new Test { BeginTime = 8.26, EndTime = 8.55 });string json = JsonHelper.ObjectToJson(timePart);List<Test> list = JsonHelper.JsonToObject<List<Test>>(json);MessageBox.Show("list==" +list.Count);}
