城市列表可以在 http://imgcache.qq.com/city_v1/js/city.js 下载
Json.net也可以在相应的地方下载
就以下贴出解析的代码(只处理了省份和城市的，如果要处理地区的，基本是相同的道理）
public static void SetComBoxCityDR(System.Windows.Forms.ComboBox cmb, string type, string json)
{
try
{
if (type == "")
{
cmb.Items.Clear();
JObject o = JObject.Parse(json);
IEnumerable<JProperty> properties = o.Properties();
foreach (JProperty item in properties)
{
if (item.Name != "n")
{
string name = GetNameCityDR(item.Value.ToString());
if (name == "")
{
name = item.Value.ToString();
}
if (item.Name != "" && name != "")
{
//Console.WriteLine(string.Format("{0}[{1}]", name, item.Name));
cmb.Items.Add(string.Format("{0}[{1}]", name, item.Name));
}
}
}
}
else
{
string temp = GetChirdCityDR(json, type);
if (temp != "")
{
SetComBoxCityDR(cmb, "", temp);
}
}
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
}
}
private static string GetChirdCityDR(string json, string id)
{
try
{
JObject o = JObject.Parse(json);
IEnumerable<JProperty> properties = o.Properties();
foreach (JProperty item in properties)
{
if (item.Name == id )
{
//Console.WriteLine(string.Format("{0}[{1}]", name, item.Name));
//cmb.Items.Add(string.Format("{0}[{1}]", name, item.Name));
return item.Value.ToString();
}
}
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
}
return "";
}
private static string GetNameCityDR(string json)
{
try
{
JObject o = JObject.Parse(json);
IEnumerable<JProperty> properties = o.Properties();
foreach (JProperty item in properties)
{
if (item.Name == "n")
{
return item.Value.ToString().Replace("\"", "");
}
}
}
catch (Exception ex)
{
Console.WriteLine(ex.Message );
}
return "";
}
调用代码也很简单
其中cmb是窗体的控件，type如果为空，表示加载省份，如果不为空，则是省份的代码，表示要加载这个省的所有城市，scity 则是地址列表的一大堆的字符串
public static void SetComboxCityDR(System.Windows.Forms.ComboBox cmb, string type)
{
ToolsDll.JsonHelper.SetComBoxCityDR(cmb,type, scity);
}
