BindingList

Undvika iteration av N * 2

Detta placeras i en Windows Forms-händelseshanterare

var nameList = new BindingList<string>();
ComboBox1.DataSource = nameList;
for(long i = 0; i < 10000; i++ ) {
    nameList.AddRange(new [] {"Alice", "Bob", "Carol" });
} 

Det tar lång tid att köra, fixa, göra nedan:

var nameList = new BindingList<string>();
ComboBox1.DataSource = nameList;
nameList.RaiseListChangedEvents = false;
for(long i = 0; i < 10000; i++ ) {
    nameList.AddRange(new [] {"Alice", "Bob", "Carol" });
} 
nameList.RaiseListChangedEvents = true;
nameList.ResetBindings();

Lägg till objekt i listan

BindingList<string> listOfUIItems = new BindingList<string>();
listOfUIItems.Add("Alice");
listOfUIItems.Add("Bob");
