谷歌地理code地图响应阵列 [英] Google Geocode Map Response Array

问题描述

我使用的是谷歌地理编码API包装库（ https：//开头code.google.com / p / GMaps实现-API网/ ），以获得/图一个完整的地址，但时不时响应不正确映射，因为谷歌并没有返回所有的地址类型和数组的索引不会体现价值的正确位置我想还是会抛出空例外。

I am using a Google Geocoding API Wrapper library (https://code.google.com/p/gmaps-api-net/) to get/map a complete address but every now and then the response doesn't map correctly because Google didn't return all the address types and the indexes on the array do not reflect the correct location of the value I want or it throws a null exception.

code

    public AddressMapper(GeocodeResponse geocodeResponse)
    {
        AddressComponents = geocodeResponse.Results[0].AddressComponents;


        if (AddressComponents != null)
        {
            StreetNumber = TryParse(AddressType.StreetNumber);
            Street = TryParse(AddressType.StreetNumber);
            Neighborhood = TryParse(AddressType.StreetNumber);
            City = TryParse(AddressType.StreetNumber);
            Province = TryParse(AddressType.StreetNumber);
            Country = TryParse(AddressType.StreetNumber);
            Political = TryParse(AddressType.StreetNumber);
            PostalCode = TryParse(AddressType.StreetNumber);
            FormattedAddress = TryParse(AddressType.StreetNumber);
            //Latitude = address.Geometry.Location.Latitude.ToString(CultureInfo.InvariantCulture);
            //Longitude = address.Geometry.Location.Longitude.ToString(CultureInfo.InvariantCulture);
        }
    }
>>> This seems to always be an empty string.
    private string TryParse(AddressType addressType)
    {
        if (AddressComponents == null) return "";
        foreach (var component in AddressComponents)
        {
            return component.Types.Contains(addressType) ? component.LongName : string.Empty;
        }
    return string.Empty;
}
}

如何/什么是确保该元素的正确方法在响应的存在？

How/What is the correct way of ensuring the element exists in the response?

推荐答案

有没有为返回类型的担保或 address_components 的顺序。

There isn't a guarantee for the returned types or the order of the address_components.

遍历所有 address_components ，测试如果类型匹配特定的类型，当它设置​​相关变量

Iterate over all address_components, test if the types match a particular type and when it does set the related variable.
