我知道...JSON.NET的Newtonsoft.Json很好用... 我知道...MS內建的jsonSerializer有bug....... 但是總有一天,環境不允許你參考外部dll,只能用到底層的時候...為了這麼一天 所以...有了這篇文... 如果json長這樣↓ [{"identityid":"1","TransAccount":null,"CmpName":"台北處","CmpNo":"8888","IdNo":"A123456789","Name":"test"},{"identityid":"2","TransAccount":null,"CmpName":"台北處","CmpNo":"9999","IdNo":"A987654321","Name":"test2"},{"identityid":"3","TransAccount":null,"CmpName":"台中處","CmpNo":"7777","IdNo":"A888888888","Name":"test3"}] 在c#裡,需要先使用datamember定義資料格式 //定義json欄位資料 [System.Runtime.Serialization.DataContract] class DrawDataRow { [DataMember(Name = "identityid")] public string identityid { get; set; } [DataMember(Name = "IdNo")] public string IdNo { get; set; } [DataMember(Name = "Name")] public string Name { get; set; } [DataMember(Name = "CmpNo")] public string CmpNo { get; set; } [DataMember(Name = "CmpName")] public string CmpName { get; set; } [DataMember(Name = "TransAccount")] public string TransAccount { get; set; } } 定義好了,才能開始寫paser的部份 string jsonContent = System.IO.File.ReadAllText("your file addrerss"), System.Text.Encoding.UTF8); System.Runtime.Serialization.Json.DataContractJsonSerializer serializer = new System.Runtime.Serialization.Json.DataContractJsonSerializer(typeof(DrawDataRow[])); //Newtonsoft.Json.Converters. using (System.IO.MemoryStream ms = new System.IO.MemoryStream(System.Text.Encoding.UTF8.GetBytes(jsonContent))) { try { DrawDataRow[] response = (DrawDataRow[])serializer.ReadObject(ms); Response.Write(response[0].Name.ToString()); } catch (Exception ex) { Response.Write(ex.ToString()); } } ！注意，讀取時要先查明你的json檔案編碼為何，在這裡是預設utf8，這個看不到的編碼挺傷腦筋的，要先確認好否則會無法正確讀取json。
