Json也可以这么使

public string GetJSON()
{

//Json数据
string json112 = "{\"control_info\":{\"imei\":\"854698532597005\", \"os\":\"android\",\"os_ver\":\"4.0\",\"app_ver\":\"1.0\", \"cp_ver\":\"1.0\",\"timestamp\":\"20130708161023\", \"user_id\":\"\",\"operation\":\"login\"},\"params\":{ \"username\":\"ZhangSan\", \"password\":\"123456\"}}";
Dictionary<string, object> dic = JsonToDictionary(json112);//将Json数据转成dictionary格式
Dictionary<string, object> dataSet = JsonToDictionary(json112);
//使用KeyValuePair遍历数据
StringBuilder strs = new StringBuilder();
foreach (KeyValuePair<string, object> item in dic)
{
if (item.Key.ToString() == "control_info")//获取header数据
{
var subItem = (Dictionary<string, object>)item.Value;
foreach (var str in subItem)
{
strs.Append(str.Key + ":" + str.Value + "\r\n");
key1 = str.Key;
value1 = str.Value.ToString();
if (key1 == "operation")
{
#region 登录login

if (value1 == "login")
{
foreach (KeyValuePair<string, object> item1 in dataSet)
{
if (item1.Key.ToString() == "params")//获取header数据
{
var subItem1 = (Dictionary<string, object>)item1.Value;
foreach (var str1 in subItem1)
{
strs.Append(str1.Key + ":" + str1.Value + "\r\n");
if (str1.Key == "username")
{
username = str1.Value.ToString();
}
if (str1.Key == "password")
{
password = str1.Value.ToString();
}
}
}
}
Login(username, password);
}
break;
#endregion
}
}
}
}
return strs.ToString();
