Hi ALL,

I am a very new to .NET.

When I want to create a setter or getter.

It is normally wrote :

public type Name{
get{
return defination;
}
set{
defination = value;
}
}

but if I this class holds a Collection,
I want to get some item by parameter, let me say:

public Type getItem(string byName);
public Type getItem(int byIndex);

How to write like setter and getter.

Thanks
 
It's called an indexer. Look it up in Google (or in Studio '05 just type
inderer and hit Tab twice and it will create one).
 
Try something like this:

class MyCustomCollection {
// I will leave you to figure out the internal storage for your
collection

public Item this[int index] {
get {
return itemList[index];
}
set {
itemList[index] = value;
}
}

public Item this[string name] {
get {
foreach(Item itm in itemList) {
if(itm.Name.Equals(name)) {
return itm;
}
return null;
}
set {
for(int i=0;i<itemList.Length;i++) {
if(itemList.Name.Equals(name)) {
itemList = value;
}
}
}
}


Usage:

MyCustomCollection coll = new MyCustomCollection();
coll[0] = new Item(...);
coll["newName"] = new Item(...);

CAUTION: The item's Name property must be unique
