如何在visual studio test explorer中显示自定义异常消息

Question

I have a custom exception class

public class CustomException : Exception
{
    string moreInfo;
    public CustomException(string message, string info) : base(message)
    {
        moreInfo = info;
    }

    public override string ToString()
    {
        return "Custom Exception Info:" + moreInfo;
    }
}

This can be thrown inside a Test so I get the following message:

Is there a way to show more info inside the Test Explorer (Without modifing the Message property)

using System;
using Microsoft.VisualStudio.TestTools.UnitTesting;

namespace UnitTestProject1
{
    [TestClass]
    public class UnitTest1
    {
        [TestMethod]
        public void TestMethod1()
        {
            throw new CustomException("aaa", "bla bla");
        }
    }
}

Update:
All my tests work fine and I have proper Assert statements.
If for some reason though any tests are broken I don't see a meaningful error in the Test Explorer, so I have to wrap each test in a try/catch and debug them one by one manually...

It's seems silly having to do that since I have all the error info I need at the time the exception is thrown

Why you will throw an exception in [TestMethod] . Proper way of testing your exception will be:

    [TestMethod]
    public void TestMethod1()
    {
        try
        {
            throw new CustomException("aaa", "bla bla");
        }
        catch(CustomException ex)
        {
            //some assert condition with proper message
            Assert.AreEqual(ex.Message, "some Stuff", "My message");
        }
    }
