如何在c#quot;中基于android手机sim网络获取用户位置;?

如何在c#quot;中基于android手机sim网络获取用户位置;?,c#,android,geolocation,C#,Android,Geolocation,我希望用户的当前位置(纬度和经度)始终只使用基于Sim卡的网络,而不使用任何其他网络(如WiFi、移动数据、GPS和其他网络,甚至所有这些都在移动中处于禁用模式)。不一定是精确的位置,甚至是近似的位置 有可能得到它吗?若你们中有人能解释并包含代码;我在谷歌上搜索,但没有得到正确的相关答案 using Android.App; using Android.Content; using Android.Runtime; using Android.Views; using Android.Widge
