在Startup中如何获取ConfigureServices方法中的开发/分段/生产主机环境？
public void ConfigureServices(IServiceCollection services)
{
// Which environment are we running under?
}
ConfigureServices方法只需要一个IServiceCollection参数。
解决方法
您可以轻松地在ConfigureServices中访问它，只需将其持久化到Startup方法中的一个属性，该方法首先被调用并将其传入，则可以从ConfigureServices访问该属性
public Startup(IHostingEnvironment env,IApplicationEnvironment appEnv)
{
...your code here...
CurrentEnvironment = env;
}
private IHostingEnvironment CurrentEnvironment{ get; set; }
public void ConfigureServices(IServiceCollection services)
{
string envName = CurrentEnvironment.EnvironmentName;
... your code here...
}
