我是否可以在Asp.net Web.API中的AppStart中自定义RequestTelemetry属性

using System.Web.Http;
using Microsoft.ApplicationInsights.Channel;
using Microsoft.ApplicationInsights.Extensibility;

namespace YourNamespace
{
    public class TelemetryConfig
    {
        public static void Initialize(HttpConfiguration config)
        {
            config.Services.Add(typeof(ITelemetryInitializer), new CustomTelemetryInitializer());
        }
    }

    public class CustomTelemetryInitializer : ITelemetryInitializer
    {
        public void Initialize(ITelemetry telemetry)
        {
            var requestTelemetry = telemetry as RequestTelemetry;
            if (requestTelemetry != null)
            {
                // 添加自定义属性和值
                requestTelemetry.Properties["CustomProperty"] = "CustomValue";
            }
        }
    }
}

protected void Application_Start()
{
    // 其他初始化代码...

    // 初始化自定义Telemetry配置
    TelemetryConfig.Initialize(GlobalConfiguration.Configuration);
}
