How can I get object instance from ()=>foo.Title expression

Question

I have a simple class with a property

class Foo 
{ 
    string Title { get; set; } 
}

I am trying to simplify data binding by calling a fun

Don't. Just modify the method to take another parameter, as described in #3444294. For your example, it may be something like this:

void BindToText(Control control, T dataSource, Expression> property)
{
    var mex = property.Body as MemberExpression;
    string name = mex.Member.Name;

    control.DataBindings.Add("Text", dataSource, name);
}

and would be called like

BindToText(titleTextBox, foo, ()=>foo.Title );

Still nice, but easy to understand. There's no magic happening. ;)
