c# - 如何在 ConfigureServices 中获取 Development/Staging/production Hosting Environment

Question

如何在 Startup 的 ConfigureServices 方法中获取 Development/Staging/production Hosting Environment？

public void ConfigureServices(IServiceCollection services)
{
    // Which environment are we running under?
}

ConfigureServices 方法只接受一个IServiceCollection 参数。

您可以在 ConfigureServices 中轻松访问它，只需在 Startup 方法期间将其持久化到一个属性，该方法首先被调用并传入，然后您可以从 ConfigureServices 访问该属性。

public Startup(IWebHostEnvironment env, IApplicationEnvironment appEnv)
{
    ...your code here...
    CurrentEnvironment = env;
}

private IWebHostEnvironment CurrentEnvironment{ get; set; } 
 
public void ConfigureServices(IServiceCollection services)
{
    string envName = CurrentEnvironment.EnvironmentName;
    ... your code here...
}
