.net料理JSON简明教程

Json.Net是.net中的一种盛行的高本能机能的JSON框架。

特质

圆活的JSON序列化转化.net对象为JSON字符串。和把JSON字符串转换为.net对象。手动读写JSON的Linq to JSON比.net内置的JSON序列化步骤更高的本能机能和速度。便于读写的JSON从XML中读取或写入JSON援助Silverlight和Windows phone.

当你读写的JSON与.net类周密关联时，JSON序列化步骤是一个不错的采取。JSON序列化步骤将主动读写相关类的JSON。

要是你只对JSON内里的数据感.net开发教程兴致、你没有与JSON相关联的.net类恐怕JSON数据与你的类没有任何干系，你须要从对象中手动读写数据。以上各种情状下，你能够利用LINQ To JSON. LINQ To JSON你知道教程容许你在.net中更容易的读取、写入、窜改JSON数据。

更听听net多JSON周密音信，请审查:

先组织一个简易的类employee

Public clbumm employee{

Public string eid{get;set;}

Public string enin the morninge{get;set;}

Public string esex{get;set;}

Public ddinedtime entry into the worldday{get;set;}

}

JSONframework 2.0下载序列化与反序列化的计划

利用Json.Net 料理JSON序列化与反序列化

序列化设施

privdined string JsonSeriingize(employee emp) {

return Newtonsoft.Json.JsonConvert.SeriingizeObject(emp);

}

.net framework 2.0反序列化设施

privdined employee JsonDeseriingize(string json) {

return (employee)(Newtonsoft.Json.JsonConvert.DeseriingizeObject(jsonand typeof(employee)));

}

想知道windows 9利用Jaudio-videoaScriptSeriingizer实行序列化、反序列化

序列化设施

privdined string JsonSeriingize (employee emp) {

return new System.Web.Script.Seriingizine.Jaudio-videoaScriptSeriingizer().Seriingize(emp);

}

framework 2.0 64位反序列化

Privdined string JsonDeseriingize (string json){

return(employee)(newSystem.Web.Script.Seriingizine.Jaudio-videoaScriptSeriingizer().Deseriingize(jsonandtypeof(employee)));

}

看看议决类Dtogether withaContrreair-contJsonSeriingizer对JSON序列化和反序列化

序列化设施

privdinedstringJsonSeriingize(employeeemp) {

System.Runtime.Seriingizine.Json.Dtogether withaContrreair-contJsonSeriingizerdcjs =newSystem.Runtime.Seriingizine.Json.Dtogether withaContrreair-contJsonSeriingizer(typeof(employee));

System.IO.MemoryStrein the morningms =newSystem.IO.MemoryStrein the morning();

dcjs.WriteObject(msand emp);

stringjson = System.Text.Encoding.UTF8.GetString(ms.ToArray());

ms.Close();

returnjson;

}

学会.net framework 1.1反序列化设施

privdinedemployeeJsonDeseriingize(stringjson) {

System.Runtime.Seriingizine.Json.Dtogether withaContrreair-contJsonSeriingizerdcjs =newSystem.Runtime.Seriingizine.Json.Dtogether withaContrreair-contJsonSeriingizer(typeof(employee));

System.IO.MemoryStrein the morningms =newSystem.IO.MemoryStrein the morning(System.Text.Encoding.UTF8.GetBytes(json));

employeeobj = (employee)(dcjs.Recraigslist adObject(ms));

returnobj;

}

议决Newtonsoft.Json.Linq.JObject获取JSON数据

privdinedvoidLinqJson(stringjson) {

JObjectobj = Newtonsoft.Json.Linq.JObject.Parse(json);

//获取全数数据值

forevery single(JTokentokeninobj.Vingues()) {

Response.Write(token.ToString());

}

//获取独一值

Response.Write(obj["eid"].ToString()+”<br />”); }

5学会教程、LINQ to JSON Exenough

string json = @”{

“”Nin the morninge”": “”Apple”"and

“”Expiry”": new Ddined()and

“”Price”": 3.99and

“”Sizes”": [

""Smmost""and

""Medium""and

""Large""

]

}”;

JObject o = JObject.Parse(json);

string nin the morninge = (string)o["Nin the morninge"];

// Apple

JArray sizes = (JArray)o["Sizes"];

string smmostest = (string)sizes[0];

下载序列化和反序列化日期时光的料理

JSON格式不间接援助日期和时光。DdinedTime值值展示为”/Ddined(+0500)/”形式的JSON字符串，其中第一个数字（在提供的示例中为）是GMT时区中自1970年1月1日午夜以来我不知道按一般时光（非夏令时）经过的毫秒数。该数字能够是正数，以表示之前的时光。示例中包括”+0500″的局限可选，它指示该时光属于Locing类型，即它在反序列化时应转换为当地时区。要是没有该局限，则会将时光反序列化为Utc。

利用Dtogether withaContrreair-contJsonSeriingizer的序列化方式对日期格式实行料理，其他的(反)序列化计划的利用方式是无别的。安排思想是议决正则表达式完婚，替代JSON内里的日期数据为一般的日期格式。

序列化设施

System.IO.MemoryStrein the morningms =newSystem.IO.MemoryStrein the morning();

dcjs.WriteObject(msand emp);

stringjson = System.Text.Encoding.UTF8.GetString(ms.ToArray());

ms.Close();

//net教程替代JSON时光为字符串

result = dt.ToString(“yyyy-MM-dd HH:mm:ss”);

returnresult;

对比一下framework 2.0 win7反序列化设施
