我要评论复制代码 代码如下:
//webclient客户端对象
webclient client = new webclient();
string url = "http://maps.google.com/maps/api/geocode/xml?latlng=" + latitude + "," + longitude + "&language=zh-cn&sensor=false";//请求地址
client.encoding = encoding.utf8;//编码格式
string responsetest = client.downloadstring(url);
//下载xml响应数据
string address = "";//返回的地址
xmldocument doc = new xmldocument();
//创建xml文档对象
if (!string.isnullorempty(responsetest))
{
doc.loadxml(responsetest);//加载xml字符串
//查询状态信息
string xpath = @"geocoderesponse/status";
xmlnode node = doc.selectsinglenode(xpath);
string status = node.innertext.tostring();
if (status == "ok") {
//查询详细地址信息
xpath = @"geocoderesponse/result/formatted_address";
node = doc.selectsinglenode(xpath);
address = node.innertext.tostring();
//查询地区信息
xmlnodelist nodelistall = doc.selectnodes("geocoderesponse/result");
xmlnode idt = nodelistall[0];
xmlnodelist idts = idt.selectnodes("address_component[type='sublocality']");
//address_component[type='sublocality']表示筛选type='sublocality'的所有相关子节点；
xmlnode idtst = idts[0];
string area = idtst.selectsinglenode("short_name").innertext;
address = address + "," + area;
}
}
address就是获取到的具体地址信息和区域信息；
