json格式的数据绑定到listview上的一些操作

功能描述：json格式的字符串——>listview显示（数据操作）——> json格式的字符串

具体代码如下：

//传入字符串：

#region:序列化字符串

string jsonData = @"{
'Results':[
{
'Client':'13-96-D8-6B-48-83-FC-A3',
'Ip':'192.168.1.150',

'PackId:':98,
'AccessTime':'2012-11-05 17:49:16'
},

'Ip':'192.168.1.151',
'Port':'51031',
'Protocol':'2',
'PackId:':99,
'AccessTime':'2012-11-05 17:49:16'
},
