C＃图表绑定到var

Question

I have var t from linq query with this structure:

    [0] = { Type = "K", Count = 1 }
    [1] = { Type = "Z", Count = 8 }

and now I want to bind it to my chart with elegance (no foreach). I try to do something like this:

    series1.Points.DataBindXY(t. ????, t.????);

but I don't know how to get "first column" and "second column" of my var. Please help

Edit: My linq query:

                var t= (from oAction in Actions
                    group oAction by oAction.Type.Name into g
                    select new { Type = g.Key, Count = g.Count() }).ToArray();

Answer 1

I have never worked with ASP.Net charts, so I'm not sure this will work, but I think it should:

series1.Points.DataBindXY(t.Select(x => x.Type), t.Select(x => x.Count));

This will assign a collection of Type values as the x values and collection of Count values as y values.

Answer 2

var t= (from oAction in Actions
                    group oAction by oAction.Type.Name into g
                    select new { Type = g.Key, Count = g.Count() }).ToArray();

All-right, so you are returning an "Anonymous" type. You can definitely access t.Type or t.Count but the catch is you can do this only inside the method where this LINQ query is defined. The scope of anonymous type is limited to the method in which it is defined. You can overcome this limitation by using "dynamic" keyword. But I haven't tried this, so can't be 100% sure.
