C# – How to get/set ListViewItem or ListViewItem.ListViewSubItem by key

clistviewsubitem

I have a listview with several items that are created dynamically, each has two subitems that are quantity and code after a query to the database should update the quantity, but to make the code more readable I would like to access subitems by the key and not by its index, something like:

subitem["quantity"]

but I don't see how to assign the key though collections.

You have to set the Name property of the ListViewItem or the ListViewSubItem to use the key.

From the ListViesSubItem documentation:

The Name property corresponds to the key for a ListViewItem..::.ListViewSubItem in a ListViewItem..::.ListViewSubItemCollection.

The same is true for the ListViewItem.

C# – How to cast int to enum

From an int:

YourEnum foo = (YourEnum)yourInt;

From a string:

YourEnum foo = (YourEnum) Enum.Parse(typeof(YourEnum), yourString);

// The foo.ToString().Contains(",") check is necessary for enumerations marked with an [Flags] attribute
if (!Enum.IsDefined(typeof(YourEnum), foo) && !foo.ToString().Contains(","))
{
    throw new InvalidOperationException($"{yourString} is not an underlying value of the YourEnum enumeration.")
}

Update:

From number you can also

YourEnum foo = (YourEnum)Enum.ToObject(typeof(YourEnum) , yourInt);

foreach (Suit suit in (Suit[]) Enum.GetValues(typeof(Suit)))
{
