Question

I’d like to get ToString() to display for a class under my control in debug mode.

It’d be nice if this was the first thing to show up when you hover over a variable with the mouse. Is there an attribute for this?

Answer 1

Mark your class with

[System.Diagnostics.DebuggerDisplay("{ToString()}")]

Test:

[System.Diagnostics.DebuggerDisplay("{ToString()}")]
class MyClass
{
    private string _foo = "This is the text that will be displayed at debugging"

    public override string ToString()
    {
        return _foo;
    }
}

Now when you hover over a variable with the mouse it will show This is the text that will be displayed at debugging.
