C# 将遥测发送到ConfigureServices内部的ApplicationInsights

我想从ConfigureServices内部发送一些遥测数据，例如，如果我缺少一个配置设置，我想向AI发送一个事件来跟踪它

public class Startup
{
   public void ConfigureServices( IServiceCollection services)
   {
      services.AddApplicationInsightsTelemetry();

      // Is there a way of getting the telemetry client here to send some telemetry?
      // e.g. TelemetryClient.TrackEvent("MyEvent");
   }
}

---

是否有任何方法可以在ConfigureServices中获取由

AddApplicationInsightsTelemetry

创建的遥测客户端？上下文在该点是否有效？

否，在

ConfigureServices

方法完成之前，我们无法在

ConfigureServices

中获取由

AddApplicationInsightsTelemetry

创建的遥测客户端

您应该在

ConfigureServices

方法中手动创建遥测客户端，如下所示：

public void ConfigureServices(IServiceCollection services)
{
    services.AddControllersWithViews();
    var s1 = services.AddApplicationInsightsTelemetry(Configuration["APPINSIGHTS_INSTRUMENTATIONKEY"]);

    TelemetryConfiguration configuration = TelemetryConfiguration.CreateDefault();
    configuration.InstrumentationKey = Configuration["APPINSIGHTS_INSTRUMENTATIONKEY"];
    var telemetryClient = new TelemetryClient(configuration);

    telemetryClient.TrackEvent("xxx");
}
