Reading from a ListBox
-
Hi. I have a listbox named lbDat. I want to read values from the listbox by using the line
lbDat.SelectedItem.ToString();
But it just gives me the namespace of my solution and a class name. What am i doing wrong and what can i do to correct this behaviour. Thank you in advance.

ToString on an object will get you the object type unless you override the ToString method. If the item with in the listbox is already a string then there is no need for the ToString. If the item is not a string you should cast it to what object type it is then access the properties you need.
var castedObject = (CustomObject)lbDat.SelectedItem;
var dataInObject = castedObject.SomeProperty;Computers have been intelligent for a long time now. It just so happens that the program writers are about as effective as a room full of monkeys trying to crank out a copy of Hamlet.

As another alternative; override the .ToString function of the class that you're stuffing in there (identified by the namespace and classname showing currently) and have it return a formatted string with the most interesting properties of the "
thisclass", somewhat similar to the example below;public override string ToString()
{
return string.Format("Class myClassName, id: {0}, name: {1}", this.someId, this.someName);
}Overriding that method has the bonus-advantage you have a string-representation in the debugger for your object.
