Early / Late Binding example in
C#
Consider we have an Order class like this,
with just one property called OrderNo
public class
Order
{
private string
strOrderNo;
public string
OrderNo
{
get
{
return
strOrderNo;
}
set
{
strOrderNo
=
value;
}
}
}
(Get and Set members are important
here)
Below is the regular code which
uses early binding as we all know :
{
Order objOrder = new
Order();
objOrder.OrderNo = "111";
MessageBox.Show(objOrder.OrderNo);
}
Below is the code which uses late binding to achieve the same as above
:
{
object obj =
Activator.CreateInstance(typeof(Order));
PropertyInfo
proInfo =
obj.GetType().GetProperty("OrderNo");
proInfo.SetValue(obj,
"222", null);
MessageBox.Show((proInfo.GetValue(obj,
null)).ToString());
}
Note:
Early binding always have higher performance as the
compiler will know beforehand what type of the object will be created and can
make optimizations accordinly.
Moreover, the VB.Net compiler (and c# compiler)
implements late binding by adding some helper functions which will
definitely have a hit on the performance.
