c/c++常用代码之四爆炸输出,jason(纯干货)

常用代码之四:创建jason,jason转换为字符串,字符串转换回jason,c#反序列化jason****字符串的几个代码片段

创建jason,并JSON.stringify()将之转换为字符串。

直接使用var customer={}, 然后直接customer.属性就可以直接赋值了。

也可以var customer = { CustomerName: CustomerName, CustomerAddress: CustomerAddress } 这样创建,它会自动将:前面的CustomerName视作属性名并加上双引号,并将后面的CustomerName当作属性值,读取变量值后也加上双引号,当然,这不如上面的方式面向对象。

提交表单前,要使用JSON.stringify()方法将jason对象转换为字符串。

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="WebAppJason._Default" %>

<asp:Button ID="Button2" runat="server" onclick="Button2_Click" Text="Button" />

 

在C#中,引用system.web.extension.dll,并using System.Web.Script.Serialization,然后直接用JavaScriptSerializer的Deserialize方法把字符串反序列化为Customer对象使用了,非常简单方便。

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Web.UI;

using System.Web.UI.WebControls;

using System.Web.Script.Serialization;

namespace WebAppJason

{

public class Customer {

public string CustomerName = "";

public string CustomerAddress = "";

}

public partial class _Default : System.Web.UI.Page

{

protected void Page_Load(object sender, EventArgs e)

{

string custr = this.customer.Value;

if (custr != null && custr.Length > 0)

{

JavaScriptSerializer jsc = new JavaScriptSerializer();

Customer c = jsc.Deserialize(custr);

this.CustomerName0.Value = c.CustomerName;

this.CustomerAddress0.Value = c.CustomerAddress;

}

}

}

}

3.使用

JSON.parse()将字符串转回jason

function abc() {

var CustomerName = document.getElementById("CustomerName").value;

var CustomerAddress = document.getElementById("CustomerAddress").value;

var customer = {};

customer.CustomerName = CustomerName;

customer.CustomerAddress = CustomerAddress;

customer = JSON.stringify(customer);

//alert(customer);

var c2 = JSON.parse(customer);

alert(c2.CustomerName + " " + c2.CustomerAddress);

document.getElementById("customer").value = customer;

}
