Why delegates are used?
Posted Date: November 05, 2009 Points: 5
Delegates are similar to pointer.
They are used to save memory.
Check this code.
Delegates are holding one or multiple function address.The delegate designed using pointers so the delegates are unsafe code from the .Net framework.The delegates are reference types.Depending upon the function prototype we have to declare the delegates.Delegates are of two types
1>Single Cast Delegate.
2>Multi Cast Delegate.
Multi Cast Delegate:
The multi Cast delegate refers multiple single cast delegate.
Example on multicast delegate:
public delegate void dname();
public void m1()
public void m2()
private void button1_Click(object sender, EventArgs e)
DelegateDemo obj = new DelegateDemo();
dname d1 = new dname(obj.m1);
dname d2 = new dname(obj.m2);
d3 = d1 + d2;
