list转成json，json转成list

list转json

方法一、

try

  {

 System.Runtime.Serialization.Json.DataContractJsonSerializer serializer = new System.Runtime.Serialization.Json.DataContractJsonSerializer(list.GetType());

  using (MemoryStream ms = new MemoryStream())

 {

    serializer.WriteObject(ms, list);

    strReturn.msg = Encoding.UTF8.GetString(ms.ToArray());

 }

 }

 catch

 {

    return null;

 }

方法二、

JavaScriptSerializer serializer = new JavaScriptSerializer();

strReturn.msg = serializer.Serialize(list);

json转list：

string jsonlist = jsonObject.msg;

JavaScriptSerializer Serializer = new JavaScriptSerializer();

list = Serializer.Deserialize<List<T>>(jsonlist);
