C# Applicationinsights自定义遥测导致ObjectDisposedException

我正在尝试为我们的application insights服务获取已连接用户的用户名，但将自定义遥测添加到日志用户名会给我一个

System.ObjectDisposedException，它发生在mscorlib.dll中，但未在用户代码中处理
错误

例外情况：

Exception thrown: 'System.ObjectDisposedException' in mscorlib.dll
An exception of type 'System.ObjectDisposedException' occurred in mscorlib.dll but was not handled in user code
Safe handle has been closed

堆栈跟踪：

System.ObjectDisposedException
  HResult=0x80131622
  Message=Safe handle has been closed
  Source=mscorlib
  StackTrace:

   at Microsoft.ApplicationInsights.TelemetryClient.Initialize(ITelemetry telemetry)

以下是我使用的代码：

 public class TelemetryInitializer : ITelemetryInitializer
    {
        private readonly IHttpContextAccessor _httpContext;
        private readonly ILogger<TelemetryInitializer> _logger;

        public TelemetryInitializer(IHttpContextAccessor httpContext, ILogger<TelemetryInitializer> logger)
        {
            _httpContext = httpContext;
            _logger = logger;
        }

        public void Initialize(ITelemetry telemetry)
        {
            var requestTelemetry = telemetry as RequestTelemetry;
            if (requestTelemetry == null) return;
            if (!requestTelemetry.Context.GlobalProperties.ContainsKey("UserName"))
            {
                if (string.IsNullOrEmpty(_httpContext.HttpContext.User.Identity.Name))
                {
                    requestTelemetry.Context.GlobalProperties.Add("UserName", "NA");
                }
                else
                {
                    requestTelemetry.Context.GlobalProperties.Add("UserName", _httpContext.HttpContext.User.Identity.Name);
                }
            }
        }
    }

公共类遥测初始化器：ITelemetryInitializer
{
专用只读IHttpContextAccessor\u httpContext；
专用只读ILogger\u记录器；
公共遥测初始化器（IHttpContextAccessor httpContext，ILogger记录器）
{
_httpContext=httpContext；
_记录器=记录器；
}
公共无效初始化（ITelemetry遥测）
{
var requestTelemetry=作为requestTelemetry的遥测；
if（requestTelemetry==null）返回；
if（！requestTelemetry.Context.GlobalProperties.ContainsKey（“用户名”））
{
if（string.IsNullOrEmpty（_-httpContext.httpContext.User.Identity.Name））
{
requestTelemetry.Context.GlobalProperties.Add（“用户名”，“NA”）；
}
其他的
{
requestTelemetry.Context.GlobalProperties.Add（“用户名”，_httpContext.httpContext.User.Identity.Name）；
}
}
}
}

有人遇到过类似的问题吗？您是如何解决的？
只是想确认一下，这是一个asp.net项目？不是.net core？您没有发布异常文本、调用堆栈或指示错误发生的位置，因此人们只能猜测。每个请求都有自己的HttpContext实例，该实例在请求结束时被销毁。@它的目标是.NET Framework 4.6.2发布完整的异常文本，包括堆栈跟踪。使用
Exception.ToString（）
可以很容易地获得。我怀疑问题出在调用
HttpContext
之后disposed@PanagiotisKanavos我已经在上面添加了完整的stacktrace。
