如何让用户选择他们的城镇，让我的应用程序就可以知道坐标 [英] How to let users choose their town, so my app can know coordinates

问题描述

我开始在C＃我的第一个开源ASP.NET项目。数据网络应用将要展示的是与城市的地理坐标密切的关系。

I am starting my first Open Source ASP.NET project in C#. Data that Web app is going to show is in close relation with geographic coordinates of towns.

现在我想要实现的用户界面，Web应用程序的用户可以选择所需的小镇，并提交形式，后面的场景我想选择的镇坐标，这样我就可以进行计算。

Now I want to implement user interface where user of web app can choose a desired town and submit form, and behind scene i want to get coordinates of chosen town, so I can make calculations.

现在我想知道是否有某种免费服务或库，它可以实现我得到想要的结果吗？

Now I wondering is there some free services or library, which can I implement to get wanted results?

请问谷歌的地图提供这个功能或者有其他服务，世界各地的城市数据库和他们的坐标？

Does Google's Maps provide this feature or there is other services with databases of towns around worlds and theirs coordinates?
