Briefly, the basic difference between generic and non-generic collections:

- Non-Generic collections - These are the collections that can hold elements of different data types. It holds all elements as object type.
So it includes overhead of type conversions.

- Generic collections - These are the collections that can hold data of same type and we can decide what type of data that collections can hold.

Some advantages of generic collections - Type Safe, Secure, reduced overhead of type conversions.

Maybe it is similar to the difference between, say, searching the info with Google [^] or Bing [^]?

<b><u>Here is the exmaple of the Generic collections
</u></b>


public class MyCustomList<MYTYPE>
{
private ArrayList m_list = new ArrayList();
public int Add(myType value)
{
return m_list.Add(value);
}

public void Remove(myType value)
{
m_list.Remove(value);
}

public myType this[int index]
{
get
{
return (myType)m_list[index];
}
set
{
m_list[index] = value;
}
}
}
