using Newtonsoft.Json;
using Newtonsoft.Json.Converters;
//把Json字符串反序列化为对象
目标对象 = JavaScriptConvert.DeserializeObject(JSON字符串,typeof(目标对象));
//把目标对象序列化为Json字符串
string Json字符串 = JavaScriptConvert.SerializeObject(目标对象);
1.引用Newtonsoft.Json.dll
2.在项目中添加引用..
一、序列化和反序列在.net项目中:
using Newtonsoft.Json;
using Newtonsoft.Json.Converters;
public partial class aaaa : System.Web.UI.Page
{
protected void Page_Load(object sender,EventArgs e)
{
Product product = new Product();
product.Name = "Apple";
product.Expiry = new DateTime(2008,12,28);
product.Sizes = new string[] { "Small","Medium","Large" };
string output = JavaScriptConvert.SerializeObject(product); //序列化JavaScriptConvert.SerializeObject
Response.Write(output);
//输出：{"Name":"Apple","Expiry":new Date(1230422400000),"Sizes":["Small","Large"]}
Product deserializeObject = (Product)JavaScriptConvert.DeserializeObject(output,typeof(Product));
//反序列化 JavaScriptConvert.DeserializeObject
Response.Write(deserializeObject.Expiry);
//输出：2008-12-28 00:00:00
}
}
public class Product
{
String _Name;
public String Name
{
get { return _Name; }
set { _Name = value; }
}
DateTime _Expiry;
public DateTime Expiry
{
get { return _Expiry; }
set { _Expiry = value; }
}
String[] _Sizes;
public String[] Sizes
{
get { return _Sizes; }
set { _Sizes = value; }
}
}
二、读取JSON
using Newtonsoft.Json;
using Newtonsoft.Json.Converters;
using System.IO;
public partial class aaaa : System.Web.UI.Page
{
protected void Page_Load(object sender,EventArgs e)
{
string jsonText = "['JSON!',1,true,{property:'value'}]";
JsonReader reader = new JsonReader(new StringReader(jsonText));
Response.Write("<table border=1><tr><th>TokenType</th><th>ValueType</th><th>Value</th></tr>");
while (reader.Read())
{
Response.Write("<tr><td>" + reader.TokenType + "</td><td>" + reader.ValueType + "</td><td>" + reader.Value + "</td></tr>");
}
Response.Write("</table>");
}
}
三、JSON写入
using Newtonsoft.Json;
using Newtonsoft.Json.Converters;
using System.IO;
public partial class aaaa : System.Web.UI.Page
{
protected void Page_Load(object sender,EventArgs e)
{
StringWriter sw = new StringWriter();
JsonWriter writer = new JsonWriter(sw);
writer.WriteStartArray();
writer.WriteValue("JSON!");
writer.WriteValue(1);
writer.WriteValue(true);
writer.WriteStartObject();
writer.WritePropertyName("property");
writer.WriteValue("value");
writer.WriteEndobject();
writer.WriteEndarray();
writer.Flush();
string jsonText = sw.GetStringBuilder().ToString();
Response.Write(jsonText);
//输出：["JSON!",{"property":"value"}]
}
}
