.NET 如何找到 CivicAddress？

Question

此代码返回一个空字符串。请问我该怎么做才能返回？

CivicAddressResolver civicResolver = new CivicAddressResolver();
CivicAddress c = civicResolver.ResolveAddress(new GeoCoordinate(39,77));
textBlock1.Text = c.City;

Answer 1

CivicAddressResolver.ResolveAddress() 的 MSDN 文档建议在尝试访问 c.City 之前检查 c.IsUnknown 是个好主意。
