Get double array from debugger in a tool window

[Markz878]

I want to be able to plot double arrays when debugging by giving the variable's name to TextBox and clicking a button.

I made a tool window, and managed to get EnvDTE.Debugger to my tool window's code behind.
Now I can use the following code to get any string variable's value from it's name:

EnvDTE.Expression expr = Debugger.GetExpression(variableName);
if (expr.IsValidValue)
{
    string type = expr.Type;
    string value = expr.Value;
    MessageBox.Show(type + " " + value);
}

But if I use the same trick to get double array's value, it just says {double[5]}.
So does anyone know how to get the array's values. I'm guessing I need to somehow get the memory address and parse the values from there, but I have no idea how to do this.

Also, can Microsoft.VisualStudio.Shell.Interop.IVsDebugger debugger = await VS.Services.GetDebuggerAsync() be used for getting debug variables, and if so how?

Any help is much appreciated!
