  <InstrumentationKey>这里输入你的API Key</InstrumentationKey>
</ApplicationInsights>

　　9.在下面的<InstrumentationKey>，输入我们Application Insight的InstrumentationKey

 <InstrumentationKey>这里输入你的API Key</InstrumentationKey>

　　具体的key，可以参考下图：

　　

　　10.我们在项目目录中，添加文件夹ErrorHandler，在该文件夹内创建类：AiHandleErrorAttribute.cs

　　该类的内容如下：

using System;
using System.Web.Mvc;
using Microsoft.ApplicationInsights;

namespace WebApplication10.ErrorHandler //namespace will vary based on your project name
{
    [AttributeUsage(AttributeTargets.Class | AttributeTargets.Method, Inherited = true, AllowMultiple = true)] 
    public class AiHandleErrorAttribute : HandleErrorAttribute
    {
        public override void OnException(ExceptionContext filterContext)
        {
            if (filterContext != null && filterContext.HttpContext != null && filterContext.Exception != null)
            {
                //If customError is Off, then AI HTTPModule will report the exception
                if (filterContext.HttpContext.IsCustomErrorEnabled)
                {   
                    var ai = new TelemetryClient();
                    ai.TrackException(filterContext.Exception);
                } 
            }
            base.OnException(filterContext);
        }
    }
}

　　11.在App_Start文件夹内，打开文件FilterConfig.cs文件。修改如下：

using System.Web;
using System.Web.Mvc;

namespace ApplicationInsightDemo
{
    public class FilterConfig
    {
        public static void RegisterGlobalFilters(GlobalFilterCollection filters)
        {
            //filters.Add(new HandleErrorAttribute());
            filters.Add(new ErrorHandler.AiHandleErrorAttribute());
        }
    }
}

　　12.最后，我们在文件夹Controllers里，修改HomeController.cs文件。

　　在方法Index()里，修改如下：

  public ActionResult Index()
        {
            //增加的代码
            var telemetry = new TelemetryClient();
            telemetry.TrackTrace("Execute finished");

            return View();
        }

　　13.启动MVC项目，我们可以在Application Insight的Transaction Search里，查看到对应的日志
