How can I resize a list ? thanks

Hi Deniel,

If it's some sort of list Control to which you are referring then:

- for WinForms set any of the Bounds, ClientSize, Size, Width or Height
properties

- for WebControl set the Width or Height properties or add custom attributes
and styles.

class A {
public int a;
}
private void func()
{
List<A> aref=new List<A>();
//dosometing
aref.resize(10000); <------ This is what i want to do
}

But there is no resize() implemeted.
Thanks for any help

Hi Deniel,

List<T> will expand on its own when you add items to the list. You can set
the Capacity, which affects how automatic resizing occurs within the List.

Thanks Dave for your answer,
I still wonder how i can sort the list based on the comparison of "a"
values

I mean
private bool comp(A aref, A bref)
{
return aref.a<bref.a;
}
if i put this function in a icomparable, implementation may become
complex,
built-in sort of List can't do this, can it ? How can I make a sort()
then ?

Hi Deniel,
here is an example of how you can sort the contents of your list using an
anonymous delegate, which makes it very simple to sort the items in the list:

class Person
{
private string name;

public Person(string name)
{
this.name = name;
}

public string Name
{
get
{
return this.name;
}
}
}
static void Main(string[] args)
{
List<Person> people = new List<Person>();

Person mark = new Person("mark");
Person bob = new Person("bob");
Person frank = new Person("frank");

people.Add(mark);
people.Add(bob);
people.Add(frank);

people.Sort(delegate(Person p1, Person p2)
{
return p1.Name.CompareTo(p2.Name);
}
);

for (int i = 0; i < people.Count; ++i)
{
Console.Out.WriteLine(people.Name);
}

Console.ReadLine();
}

HTH
Mark.

Hi Deniel,

Try the following code:

List<int> list = new List<int>();
list.Add(10);
list.Add(3);
list.Add(16);

list.Sort(
delegate(int i1, int i2) // anonymous method
{
return i1.CompareTo(i2);
});
