Can a debugger tell me the foreach loop account / status?

Question

Suppose I have the following code:

List<SomeObject> someObjects = ReturnListWithThousandsOfObjects();

foreach(SomeObject someobject in someObjects)
{
   DoSomething.With(someObject);
}

And also suppose that after a minute of work I set a breakpoint at DoSomething.With(someObject);.

The debugger is great for me. But now I want to know at what point I am in my iteration of the list (suppose the list is unordered / does not have a key).

Is there a way for the debugger to say: " foreachcompleted 532 out of 2321 iterations"?

Answer 1

As debugging one of them there is no index method?

i.e.

quickwatch - someObjects.indexOf (someObject);

Added - Sorry if a little short.

Guffa, , EqualComparer (, GetHashCode/Equals).

    public class ATest
    {
        public int number { get; set; }
        public int boo { get; set; }
        public ATest()
        {

        }
    }

    protected void Go()
    {
        List<ATest> list = new List<ATest>();

        foreach(var i in Enumerable.Range(0,30)) {
            foreach(var j in Enumerable.Range(0,100)) {
                list.Add(new ATest() { number = i, boo = j });                  
            }
        }

        var o =0; //only for proving concept.
        foreach (ATest aTest in list)
        {               
            DoSomthing(aTest);
            //proof that this does work in this example.
            o++;
            System.Diagnostics.Debug.Assert(o == list.IndexOf(aTest));
        }

    }
