不管什么都可以，只要能输入一个地址，获取经纬度两个参数就行了，请教大家

class Getgeo
{
public struct geo
{
public string Latitude;
public string Longtitude;
}

public static geo Getgeo(
string location)
{

string geo="";
geo mygeo = new geo();
string results = String.Empty;
HttpWebRequest searchRequest =
(HttpWebRequest)WebRequest.Create(@"http://maps.google.com/maps?f=q&geocode=&q="+location +"&output=js");
WebResponse myresponse = searchRequest.GetResponse();
Stream responseStream = myresponse.GetResponseStream();
byte[] buffer = new byte[9999 ];
responseStream.Read(buffer, 0, (int)9999);
results = System.Text.Encoding.ASCII.GetString(buffer);
System.Text.RegularExpressions.Regex myregex = new Regex(@"center..lat\:[^,]+,lng\:.{0,1}[0-9]+.[0-9]+");
MatchCollection mc = myregex.Matches(results);

foreach (Match mymatch in mc)
{
geo = mymatch.Value;
string latitude=geo .Substring (geo .IndexOf ("lat:")+4,5);
string longtitude=geo .Substring (geo .IndexOf ("lng:")+4,5);

mygeo.Latitude = latitude;
mygeo.Longtitude = longtitude;
if (mygeo.Latitude == null)
{
System.Windows.Forms.MessageBox.Show("Null seen");
}
}
myresponse.Close();

responseStream.Close();

myresponse.Close();
return mygeo;
}

public static string GetLongtitude(
string location)
{

geo mygeo = Getgeo(location );
return mygeo.Longtitude;

}


public static string GetLatitude(
string location)
{
geo mygeo = Getgeo(location );
return mygeo.Latitude;

}
}
请问这个代码如何改成我需要的：从一个textbox获取地址，点击按钮，在两个label中显现经纬度，这个怎么引用过来呢
