用于C#的Google Maps API

我真的很新用于使用API​​所以在查看谷歌地图Api页面后我不确定是否有设计用于C#的API.如果我可以在C#上使用谷歌地图API,我不需要谷歌地图在我的应用程序上显示所有我需要知道. 这是我想要使用的那个

我在很多地方寻找它,但我能找到的只是使用Gmaps的替代品,但那不是我想要的.

¿有可能使用它吗？

1.自己创建对Google Maps API的请求

您只需将HTTP请求发送到Google Maps API,然后使用结果即可.您可以使用WebRequest伪造对google api的请求.您需要 Maps API密钥.

你必须建立GET参数,例如.origin=...&destination=...&key=YOUR_API_KEY+解析JSON响应以对其执行某些操作.

Google Maps Api文档(在Web服务API下)列出了请求参数和示例响应.

string url = @"https://maps.googleapis.com/maps/api/directions/json?origin=75+9th+Ave+New+York,+NY&destination=MetLife+Stadium+1+MetLife+Stadium+Dr+East+Rutherford,+NJ+07073&key=YOUR_API_KEY";

WebRequest request = WebRequest.Create(url);

WebResponse response = request.GetResponse();

Stream data = response.GetResponseStream();

StreamReader reader = new StreamReader(data);

// json-formatted string from maps api
string responseFromServer = reader.ReadToEnd();

response.Close();

JSON响应看起来像这样(来自Directions API )

2. ...或使用专用库

gmaps-api-net(github)为Google Maps提供api界面.你可以通过nuget获得它.我没有测试它,但它看起来很容易使用.
