Hallo,
hier ein Beispiel f�r eine Klasse ProductProperty, welche
die Properties
ProductPropertyID,
ProductPropertyName,
ProductPropertySign und
productPropertyUnit
hat.
Gruss
Alex
P.S.: Bitte keine HTML-Mails.
public class ProductPropertyCollection : ArrayList
{
public enum CollectionFields {
ProductPropertyID,
ProductPropertyName,
ProductPropertySign,
productPropertyUnit
}
public void Sort(CollectionFields sortField, bool isAscending) {
switch (sortField) {
case CollectionFields.ProductPropertyID:
base.Sort(new ProductPropertyIDComparer());
break;
case CollectionFields.ProductPropertyName:
base.Sort(new
ProductPropertyNameComparer());
break;
case CollectionFields.ProductPropertySign:
base.Sort(new
ProductPropertySignComparer());
break;
case CollectionFields.productPropertyUnit:
base.Sort(new
productPropertyUnitComparer());
break;
}
if (!isAscending) base.Reverse();
}
private sealed class ProductPropertyIDComparer : IComparer {
public int Compare(object x, object y) {
ProductProperty first = (ProductProperty) x;
ProductProperty second = (ProductProperty) y;
return
first.ProductPropertyID.CompareTo(second.ProductPropertyID);
}
}
private sealed class ProductPropertyNameComparer : IComparer {
public int Compare(object x, object y) {
ProductProperty first = (ProductProperty) x;
ProductProperty second = (ProductProperty) y;
return
first.ProductPropertyName.CompareTo(second.ProductPropertyName);
}
}
private sealed class ProductPropertySignComparer : IComparer {
public int Compare(object x, object y) {
ProductProperty first = (ProductProperty) x;
ProductProperty second = (ProductProperty) y;
return
first.ProductPropertySign.CompareTo(second.ProductPropertySign);
}
}
private sealed class productPropertyUnitComparer : IComparer {
public int Compare(object x, object y) {
ProductProperty first = (ProductProperty) x;
ProductProperty second = (ProductProperty) y;
return
first.ProductPropertyUnit.CompareTo(second.ProductPropertyUnit);
}
}
}
ich m�chte eine ArrayList sortieren, allerdings wei� ich nicht wie
ich das anstellen soll. Inmeiner ArrayList gibt es eine unterschiedliche
Anzahl an Elementen, jedes dieser Elemente besitzt ein Attribut �Position�,
anhand dieser Position soll die ArrayList sortiert werden, wei� jemand Rat?
Gr��e Dirk
