C# 实现的 Google Maps API 接口库使用教程

【实例简介】

该库允许开发者在Microsoft .NET环境下，使用C#语言与Google Maps API进行交互，支持包括地理编码、海拔、静态地图、路线、距离矩阵、地点、时区和街景等Google Maps API的全部功能。

快速示例：

GoogleSigned.AssignAllServices(new GoogleSigned("YOUR_API_KEY"));

var request = new GeocodingRequest();
request.Address = "1600 Pennsylvania Ave NW, Washington, DC 20500";
var response = new GeocodingService().GetResponse(request);

if(response.Status == ServiceResponseStatus.Ok && response.Results.Count() > 0)
{
    var result = response.Results.First();

    Console.WriteLine("Full Address: "   result.FormattedAddress);
    Console.WriteLine("Latitude: "   result.Geometry.Location.Latitude);
    Console.WriteLine("Longitude: "   result.Geometry.Location.Longitude);
}
else
{
    Console.WriteLine("Unable to geocode.  Status={0} and ErrorMessage={1}", response.Status, response.ErrorMessage);
}

以上代码展示了如何使用该库进行地理编码服务的请求，并处理响应结果。
