我开发了一个全局异常处理中间件，并尝试将异常传递给ErrorCotroller我的 ASP.NET Core MVC 应用程序。

中间件：

public class GlobalExceptionHandlingMiddleware
{
    private readonly RequestDelegate _next;         

    public GlobalExceptionHandlingMiddleware(RequestDelegate request)
    {
        _next = request; 
    }

    public async Task Invoke(HttpContext httpContext)
    {
        try
        {
            await _next(httpContext);
        }
        catch(Exception ex)
        {
            await HandleExceptionAsync(httpContext, ex);
        }
    }

    private async Task HandleExceptionAsync(HttpContext httpContext, Exception ex)
    {           
        httpContext.Response.Redirect("/Error/Error");
        httpContext.Items["exception"] = ex;
    }
} 

ErrorController:

public class ErrorController : Controller
{
    private readonly ILogger<ErrorController> _logger;

    public ErrorController(ILogger<ErrorController> logger)
    {
        _logger = logger;
    }        

    [Route("/Error/Error")]
    public IActionResult Error()
    {
        Exception exec = (Exception)HttpContext.Items["exception"];
        ViewData["message"] = exec.Message;
        _logger.LogError(exec, "Internal server error");
        return View("Error");
    }  
}

我尝试使用HttpContext.Items["exception"]将异常传递给ErrorController，但没有成功。

我怎样才能实现这个目标？
